PREFACE 

Federal radiation protection guidance is developed by the Administrator of the 

Environmental Protection Agency as part of his or her responsibility, under Executive Order 10831, 

to "... advise the President with respect to radiation matters, directly or indirectly affecting health, 

including guidance for all Federal agencies in the formulation of radiation standards and in the 

establishment and execution of programs of cooperation with States." The purpose of Federal 

guidance is to provide a common framework to ensure that the regulation of exposure to ionizing 

radiation is carried out in a consistent and adequately protective manner. 

This Federal guidance report is the third of a series designed to provide technical information 

useful in implementing radiation protection programs. It is our hope that it will help ensure that 

regulation of exposure to radiation is carried out in a consistent manner that makes use of the best 

available information for relating concentrations of radioisotopes in environmental media to dose 

in human populations due to external radiation. The dose coefficients in this report are intended for 

use by Federal agencies having regulatory responsibilities for protection of members of the public 

and/or workers, such as the Environmental Protection Agency, the Nuclear Regulatory Commission, 

and Occupational Health and Safety Administration, as well as by those Federal agencies with 

responsibilities related to the management of their own and their contractor operations, such as the 

Department of Energy and the Department of Defense. We also encourage their use by State and 

local authorities. 

Exposure to external radiation from contaminated soil, which is a central focus of the 

calculations carried out to produce this report, is a particularly timely subject. The Nation is at the 

beginning of perhaps the largest cleanup operation in its history, at the large collection of sites 

involved in the development of nuclear weapons and commercial nuclear power during the past half 

century. An accurate assessment of this exposure pathway is essential to the decisions that will be 

required to regulate, manage, and verify this cleanup. 

The principal dose quantity, effective dose equivalent, has been calculated with the 

weighting factors used in Federal Guidance Report No. 11, which were those recommended in 

Radiation Protection Guidance to Federal Agencies for Occupational Exposure (EPA, 1987). 

iii 
iv 

New estimates of radiation risk to the organs and tissues have been published since then 

(UNSCEAR, 1988; NAS, 1990) and updated weighting factors have been recommended by the 

International Commission on Radiological Protection (ICRP, 1991). However, new weighting 

factors have not yet been adopted for use in the United States and would require a number of 

adjustments to existing regulations. As the report notes, for most radionuclides these dose 

coefficients are not very sensitive to the choice of weighting factors. We are reviewing new 

weighting factors, as well as EPA's own estimates of organ-specific risk factors, and we will propose 

changes in the weighting factors as soon as it appears necessary and reasonable to do so. At that 

time, we will also publish revised versions of this report and of Federal Guidance Report No. 11. 

The tables in this report are also available as computer files so that they may be more easily 

used in programs for assessing dose. We are simultaneously making the tables for internal exposure 

contained in Federal Guidance Report No. 11 available in the same format. Instructions for 

obtaining both of these sets of computer files may be found at the back of this report. 

We gratefully acknowledge the work of the authors, Keith F. Eckerman and Jeffrey C. 

Ryman, without whose outstanding contributions over the past several decades tables such as these 

would not exist. This project was made possible through joint funding from three Federal agencies: 

the Department of Energy (DOE), the Nuclear Regulatory Commission (NRC), and the 

Environmental Protection Agency. We appreciate the consistent support of the DOE and NRC 

project officers, C. Welty and N. Varma, and S. Yaniv and R. Meck, respectively, throughout the 

lengthy term of this work. We also are indebted to H. Beck, S. Y. Chen, C. M. Eisenhauer, P. Jacob, 

G. D. Kerr, D. C. Kocher, and C. B. Nelson for their technical reviews. The report has been clarified 

and strengthened through their efforts. We would appreciate being informed of any errors or 

suggestions for improvements so that these may be taken into account in future editions. Comments 

should be addressed to Allan C. B. Richardson, Deputy Director for Federal Guidance, Criteria and 

Standards Division (6602J), U. S. Environmental Protection Agency, Washington, DC 20460.

I. INTRODUCTION

This report tabulates dose coefficients for external exposure to photons and electrons emitted 

by radionuclides distributed in air, water, and soil. It is intended to be a companion to Federal 

Guidance Report No. 11 (Eckerman et al., 1988), which tabulated dose coefficients for the 

committed dose equivalent to tissues of the body per unit activity of inhaled or ingested 

radionuclides. The dose coefficients for exposure to external radiation presented here are intended 

for the use of Federal agencies in calculating the dose equivalent to organs and tissues of the body, 

as were those in Federal Guidance Report No. 11. Note that the dose coefficients for air submersion 

in this report update those given in Federal Guidance Report No. 11. 

These dose coefficients are based on previously developed dosimetric methodologies, but 

include the results of new calculations of the energy and angular distributions of the radiations 

incident upon the body and the transport of these radiations within the body. Particular effort was 

devoted to expanding the information available for the assessment of the radiation dose from 

radionuclides distributed on or below the surface of the ground. Details of the underlying 

calculations and of changes from previous work are presented in Section II and in the appendices. 

Dose coefficients for external exposure relate the doses to organs and tissues of the body to 

the concentrations of radionuclides in environmental media. Since the radiations arise outside the 

body, this is referred to as external exposure. This situation is in contrast to the intake of 

radionuclides by inhalation or ingestion, where the radiations are emitted inside the body. In either 

circumstance, the dosimetric quantities of interest are the radiation doses received by the more 

radiosensitive organs and tissues of the body. For external exposures, the kinds of radiation of 

concern are those sufficiently penetrating to traverse the overlying tissues of the body and deposit 

ionizing energy in radiosensitive organs and tissues. Penetrating radiations are limited to photons, 

including bremsstrahlung, and electrons. The radiation dose depends strongly on the temporal and 

spatial distribution of the radionuclide to which a human is exposed. The modes considered here 

for external exposure are: 

- submersion in a contaminated atmospheric cloud, i.e., air submersion,

- immersion in contaminated water, i.e., water immersion, and

- exposure to contamination on or in the ground, i.e., ground exposure.

Estimation of the dose to tissues of the body from radiations emitted by an arbitrary


1

2


distribution of a radionuclide in an environmental medium is an extremely difficult computational 

task. Therefore, it has become common practice to consider simplified and idealized exposure 

geometries; i.e., the radionuclide concentration in the medium, seen from the location of an exposed 

individual, is uniform and effectively infinite or semi-infinite in extent. In particular, a semi-infinite 

source region is assumed for submersion in contaminated air (Poston and Snyder, 1974) and an 

infinite source region is assumed for immersion in contaminated water and exposures to 

contaminated soil (Kocher, 1981). Even for simplified geometries, calculation of the energy and 

angular distributions of radiations incident on the body and the transport of radiation within the body 

is a demanding computational problem. 

If one assumes an infinite or semi-infinite source region with a uniform concentration C(t) 

of a radionuclide at time t, then the dose equivalent in tissue T, HT, can be expressed as 

HT  hT C ( t ) dt , (1) 

where hT denotes the time-independent dose coefficient for external exposure. The coefficient hT 

represents the dose to tissue T of the body per unit time-integrated exposure, expressed in terms of 

the time-integrated concentration of the radionuclide; that is, hT is defined as 

HT h  T . (2) C( t ) dt 

An alternative interpretation considers hT to represent the instantaneous dose rate in organ T per unit 

activity concentration of the radionuclide in the environment. In most applications, the dose HT, not 

the instantaneous dose rate, is the quantity of interest, and thus the time integral of the concentration 

must be evaluated. Note that limits of integration have not been specified in Eqs. (1) and (2) since 

they depend upon the nature of the dose quantity HT. For example, if HT is to represent the dose 

associated with a single year of exposure then the integration in Eq. (1) would range from t0 to t0 + 1 

years, where t0 is the year of interest. However, if it were to represent the dose associated with a 

particular practice, e.g., annual emissions from a facility, then the integral might range over many 

years as the emitted radionuclide persists in the environment. Depending on the nature of the 

application it may be advantageous to view the numerical value of the coefficient hT as either the 

instantaneous dose rate per unit concentration or as the dose per unit time-integrated concentration. 

In this report we follow the latter presentation. 

The dose coefficient hT for a specific radionuclide is uniquely determined by the type, 
3


intensity, and energy of the emitted radiations, the mode of exposure, and the anatomical variables 

that govern the energy deposition in organ or tissue T. The dose coefficient incorporates the 

transport of emitted radiations in the environment, their subsequent transport in the body, and 

estimation of the deposition of ionizing energy in the tissues of the body. Calculations of dose 

coefficients, as performed for this report, involve three major steps: 

(1) computation of the energy and angular distributions of the radiations incident 

on the body for a range of initial energies of monoenergetic sources distributed in 

environmental media of interest; 

(2) evaluation of the transport and energy deposition in organs and tissues of the 

body of the incident radiations, characterized above in terms of their energy and 

angular distributions, for each of the initial energies considered; and 

(3) calculation of the organ or tissue dose for specific radionuclides, considering 

the energies and intensities of the radiations emitted during nuclear transformations 

of those nuclides. 

The result of the first two steps is a set of dose coefficients for monoenergetic sources of photon or 

electron radiations. The last step simply scales these coefficients to the emissions of the 

radionuclides of interest. 

A number of reports have tabulated dose coefficients for external irradiation of the body 

from radionuclides distributed in the environment (Poston and Snyder, 1974; Dillman, 1974; O'Brien 

and Sanna, 1978; Koblinger and Nagy, 1985; Jacob et al., 1986, 1988a, 1988b; Kocher, 1981, 1983; 

DOE, 1988; Saito et al., 1990; Chen, 1991; Petoussi et al., 1991). Because of limitations in 

computational methods or available information, some of these efforts have used oversimplified 

assumptions regarding the exposure conditions. For example, the radiations incident upon the body 

have often been assumed to be uniformly distributed in angle (an isotropic field) or to be incident 

perpendicular to the body surface while the body is uniformly rotated about its vertical axis (a 

rotational exposure). Variations in the intensity of the radiations with height above the ground 

frequently have been ignored in assessing the dose from radionuclides on or below the ground 

surface. In addition, bremsstrahlung has generally been ignored, despite the fact that for many 

radionuclides (e.g., pure beta emitters), it is the only source of radiation sufficiently penetrating in 

nature to result in a dose to underlying tissues of the body. In this report, we have attempted to 

address each of these aspects of the problem without the use of simplifying assumptions that would 

significantly alter the results. 

The report is organized as follows. Section II describes the calculation of the dose 

coefficients. It also compares our results for monoenergetic photon sources to those of other 
4


researchers. Tabulations of coefficients for the extensive list of 825 radionuclides contained in 

Publication 38 of the International Commission on Radiological Protection (ICRP, 1983) are 

presented in Section III for each of the three exposure pathways. Section IV addresses some 

practical issues regarding application of the numerical data presented in Section III. 

Further details of the computational methods are discussed in the appendices. Appendix A 

contains information on the radionuclides considered in this work that is needed for proper 

application of the dose coefficients. Of particular note is the information required to evaluate 

radioactive decay chains. Appendix B gives details of modifications to the adult anatomical model 

(Cristy and Eckerman, 1987) used in these calculations. The evaluation of bremsstrahlung yield 

from distributed beta emitters is discussed in Appendix C. Appendix D provides some sample 

calculations illustrating the application of external dose coefficients. 
II. CALCULATIONAL METHODS 

Photons and electrons are the most important radiations emitted by radionuclides 

distributed in the environment that can penetrate the body from outside to deposit ionizing 

energy within its radiosensitive tissues. This section presents the methods used to calculate the 

dose coefficients for external exposure to photons and electrons for submersion in contaminated 

air, immersion in contaminated water, and exposure to contaminated ground surfaces and 

volumes. 

Some radionuclides produce bremsstrahlung that is sufficiently penetrating to be of 

potential importance in the estimation of external dose. In this work, the contribution from 

bremsstrahlung has been evaluated for all the exposure modes, as discussed in Appendix C. 

In rather unusual circumstances, spontaneous fission might also produce penetrating radiations 

of potential importance. This process has not been taken into account in calculating the dose 

coefficients presented in this report, although the data of Appendix A indicate the frequency 

of spontaneous fission. 

Dosimetric quantities 

The dose quantities addressed in this report are those used in radiation protection, 

namely the dose equivalent in various tissue and organs of the body and the effective dose 

equivalent as defined by the ICRP (1977) and adopted in 1987 for use in regulating 

occupational exposure in the United States (EPA, 1987). Since only penetrating radiations of 

low linear energy transfer (LET) are able to contribute to the dose to organs and tissues of the 

body, the dose equivalent and absorbed dose quantities in a tissue are numerically equal. That 

is, the radiation quality factor is unity for the radiations of concern here. The ICRP, in its 1990 

radiation protection recommendations (ICRP, 1991), adopted a new dosimetric quantity1

, the 

effective dose, designated by E. Both the effective dose and the effective dose equivalent 

1

In its 1990 recommendations the ICRP introduced less cumbersome names for the dosimetric 

quantities of radiation protection. The terms dose equivalent and effective dose equivalent were 

replaced by equivalent dose and effective dose, respectively. Strictly speaking, the newer 

quantities involve some differences from the earlier quantities in their definitions; for the most 

part, these details are not of concern here. 

5 
6 

quantities are weighted sums of the doses to radiosensitive tissues of the body. The effective 

dose equivalent HE, and the effective dose E, are defined as: 

HE  wT HT ,  (3a) T 



T 

and 

 E HT , (3b)  wT

where HT is the mean dose equivalent to organ or tissue T, the wT are a specific set of weighting 

 factors, and the are a set of weighting factors not specified as part of the definition of w E, and T 

can take any assigned values. Thus, the effective dose equivalent can be interpreted as a 

particular example of the effective dose. Values for wT and the current recommendations of the 

  ICRP for wT are shown in Table II.1. The factors wT and correspond to the fractional wT 

contribution of organ or tissue T to the total risk of stochastic health effects when the entire 

body is uniformly irradiated. As seen in Table II.1, the weighting factors currently 

recommended by the ICRP to compute the effective dose explicitly consider a greater number 

of organs and tissues of the body. In addition the two sets of weighting factors differ in the 

manner that the dose to tissues not explicitly identified (the remainder) is evaluated. Of a more 

fundamental nature, it should be noted that the measures of health detriment used to derive the 

two sets of weighting factors are different. The weighting factors for the effective dose 

equivalent characterize the health detriment in terms of the risk of fatal cancers and hereditary 

defects in the first two generations. In the case of the currently recommended factors for 

effective dose, the health detriment is characterized by a weighting of the risks for both fatal 

and nonfatal cancers, the risk of hereditary defects over all future generations, and the relative 

loss of life expectancy, given a fatal cancer or a severe genetic disorder. 

Since no decision has been made, at the time of this report, on changes in weighting 

factors for use in the United States, the tabulations by radionuclide of the dose coefficients in 

this report are based on the weighting factors specified for the effective dose equivalent 

quantity, the quantity used in Federal Guidance Report No. 11 (Eckerman et al., 1988). 

However, the effective dose, computed with the weighting factors currently recommended by 

the ICRP, is included in many of the preliminary tabulations and discussions. The results 

indicate that for many radionuclides of practical significance, for the exposure geometries 

considered here, the differences are small - on the order of a few percent. However, in some 

cases the differences can be large, so that specification of the wT is an important consideration. 
7


Zankl et al. (1992) have also investigated these differences for various external irradiation 

geometries and a few key radionuclides and reach similar conclusions. 

The coefficient relating the dose equivalent HT in organ or tissue T to the time integral 

of the nuclide's concentration in the environment is denoted by hT. The notation and tabulation 

of the dose coefficients presented in this report follow the conventions and format of Federal 

Guidance Report No. 11. The radionuclide tabulations include the coefficients for the gonads, 

breast, lung, red marrow, bone surface, thyroid, and remainder, followed by that for the 

effective dose equivalent. The coefficient for the remainder group is the average of the doses 

to each of the five tissues comprising the remainder and thus wT = 0.3 is applied to this 

numerical value to compute the effective dose equivalent. Although skin is excluded from the 

effective dose equivalent, we have included it in the tabulations since it frequently is the most 

highly irradiated tissue for external exposure.

remainder.

Organ doses from monoenergetic environmental photon sources 

The calculation of organ doses from irradiation of the human body by photon emitters 

distributed in the environment requires the solution of a complex radiation transport problem. 

It is impractical to solve this problem for the precise spectrum of photons emitted by each 

radionuclide of interest. Therefore, organ doses were computed for monoenergetic photon 

sources at twelve energies from 0.01 to 5.0 MeV. The results of these calculations were then 

used to derive the dose coefficients in Tables III.1 through III.7, taking into account the detailed 

photon spectrum of each radionuclide. The following pages describe the methods used to 

compute organ dose coefficients for those monoenergetic sources. 

Previous estimates of submersion dose (Poston and Snyder, 1974; O'Brien and Sanna, 

1978; Eckerman et al., 1980; Kocher, 1981, 1983; DOE, 1988) were based on Monte Carlo 

calculations with (1) poor statistics for some organ doses (due to the limitations of early 

computer systems) or (2) minor errors in sampling the radiation field. It should be noted that 

Saito et al. (1990) have recently published a compilation of organ doses due to air submersion 

based on modern Monte Carlo methods that appears to overcome these limitations. 

The seminal work of Beck and de Planque (1968) on dose due to contaminated soil, 

while accurately reflecting the radiation field, was limited to calculation of air dose for energies 

between 0.25 and 2.25 MeV, although the data were later used to generate a tabulation of air 

exposure rates for a number of nuclides (Beck, 1980). The next generation of calculations 

(Kocher, 1981, 1983; DOE, 1988; Kocher and Sjoreen, 1985) produced useful dose estimates 

for many nuclides, but was limited by simplifying assumptions regarding the energy and 

angular dependence of the radiation field (assumed to be equivalent to that for submersion) and 

the use of the point kernel method for characterizing the field strength. More recent efforts 

(Williams et al., 1985; Koblinger and Nagy, 1985; Jacob et al., 1986, 1988a, 1988b; Saito et 

al., 1990; Petoussi et al., 1991) have used relatively sophisticated methods for analyzing the 

energy, angular, and spatial dependence of the radiation field and computing organ doses for 

both mathematical and CT-derived phantoms of various ages. These data are primarily for plane 

sources at or near the air-ground interface, or for naturally-occurring radionuclides distributed 

to effectively infinite depth in the soil. The calculations of Chen (1991) include volume sources 

of many thicknesses as well as plane sources at the interface, but are only for effective dose 

equivalent based upon rotational normal beam exposure (ICRP, 1987). 

The computational methods used in this work were chosen to give an accurate 

characterization of the energy and angular dependence of the radiation field incident on the 

body, since dose to the body is very sensitive to the direction of incident radiation, and also to 
9


overcome other limitations of earlier calculations. Organ doses were computed for 25 organs 

in an adult hermaphrodite phantom (Cristy and Eckerman, 1987). The mathematical phantom 

was modified, as described in Appendix B, to include the esophagus, a tissue given an explicit 

weighting factor in the current effective dose formulation of the ICRP (1991), and to improve 

the modeling of the neck and thyroid. 

General description of the calculations 

Estimating organ dose in a human phantom exposed to radiation from an external source 

consists of calculating an effect of interest in a geometrically complex object located in an otherwise 

geometrically simple (one- or two-dimensional) system. This process is mathematically described 

by the time-independent neutral-particle Boltzmann transport equation: 

  ̄  ̄ ̄  ̄ (  ̄r, E , ) μ(  ̄r, E) ( ̄r, E , ) 

  dE  d ̄  ̄  ̄  ̄  ̄ (4)  μs (  ̄r, E 

E ,) (  ̄r, E , ) S (  ̄r, E ,), 

where 

(  ̄r, E ,  ̄ ) dE d  ̄ = angular fluence at position r ̄ with energy in dE about E and direction 

 ̄ about direction  ̄ in solid angle d ;


μ(  ̄r, E ) = linear attenuation coefficient at positionr ̄ , and energy E; 

E,  ̄  ̄  ̄  (  ̄r, E  ) dE d the probability per unit path length that a particle with initial energy E  μs  =


and direction  ̄  will undergo a scattering collision at point r ̄ and 

 ̄ about  ̄ emerge with energy in dE about E and in d ; and

 ̄  ̄ S(  ̄r, E , ) dE d =
 number of source particles emitted at position r ̄ with energy in dE

 ̄ about  ̄ about E and direction in d .


Equation (4) is conveniently written in operator notation as 

Hˆ (  ̄p )  S (  ̄p ), (5) 

where p ̄ represents position, energy, and direction phase space. 

After the solution to Eq. (4) is obtained, the organ dose is computed from the following 

integral: 

HT p ̄ T 

(  ̄p ) R (  ̄p ) dp ̄ , (6) 

where

HT = the effect of interest, i.e.,the organ dose; 

p ̄ T = phase space of tissue or organ T; and 

R (  ̄p ) = the response function, i.e., the contribution to HT due to unit angular fluence. 
10 

In principle, Eqs. (5) and (6) can be solved directly using Monte Carlo methods. 

However, this direct approach involves a combination of deep penetration (i.e., transport 

through many mean free paths of air and/or soil) and complex geometry (the human phantom). 

Calculations of this type require the use of sophisticated variance reduction techniques to 

overcome the inherent statistical nature of the Monte Carlo method. Often, the important 

regions of phase space are undersampled, and the effect of interest is underestimated 

(Armstrong and Stevens, 1969). To avoid the difficulties associated with a direct Monte Carlo 

solution, the solution is broken into two steps, using an important property of the transport 

equation. 

In a problem involving distributed radiation sources and an effect on a target (the organ 

dose), a model using a closed surface surrounding the target can be postulated to estimate the 

effect (a closed surface surrounding the sources is equivalent). One can also consider a second 

model in which the target and its surrounding medium are the same, but on the other side of the 

closed surface is a vacuum or a perfect absorber. In the second model, an area source is 

constructed on the closed surface such that the strength per unit area in each direction and at 

each energy, SA(  ̄rs ,  ̄ s ,  ̄ , E ) r ̄s j (  ̄r n , at each point on the surface is equal to the flow rate , E )
at 

the corresponding point in the first problem. It is possible to show rigorously (Chilton et al., 

1984) that the effect on the target (organ dose in this application) is the same for both problems. 

Therefore, the sources for the first model may be replaced by the flow rate they create at the 

closed surface bounding the second model. 

The problem of computing organ dose from environmental photon sources may thus be 

broken into two independent steps: (1) the calculation of the radiation field incident on a closed 

surface surrounding the human phantom model, and (2) the calculation of organ dose due to a 

surface source equivalent to the angular flow rate entering the boundary surrounding the 

phantom. To eliminate the geometric complexity of the human phantom from the calculation 

of the incident radiation field, the phantom must be removed from the problem. This may be 

done if the presence of the phantom in the original problem does not significantly perturb the 

incoming angular flow rate across the boundary surrounding the phantom. The phantom can 

affect the incoming directions of the radiation field only for those photons which, having 

interacted in the phantom, pass out of the surrounding surface, scatter in the surrounding media, 

and return across the boundary. This should be, at most, a second-order effect. Saito et al. 

(1990) have demonstrated that this perturbation is, as expected, not significant. 

For the environmental photon sources considered in this report, the calculation of organ 

dose was broken into two independent calculations, as described above. The calculation of the 
11


radiation field due to a unit source strength was performed by methods appropriate to the kind 

of source, as described later. Then, an equivalent source was constructed on a cylindrical 

surface surrounding the phantom, and the organ doses resulting from this source were computed 

for all cases by the Monte Carlo method, also described later. The two steps of the calculation 

are illustrated in Figs. II.1 and II.2 for the case of a contaminated soil source (an isotropic plane 

source at depth dS). 

Description of the environmental sources 

The source for the submersion dose calculations is a semi-infinite cloud containing a 

uniformly-distributed monoenergetic photon emitter of unit strength (1 Bq m-3) surrounding a 

human phantom standing on the soil at the air-ground interface. The air composition, given in 

Table II.2, is for conditions of 40% relative humidity, a pressure of 760 mm Hg, a temperature 

of 20 C, and a density of 1.2 kg m-3. The dose coefficients for submersion can be readily 

scaled to account for a different air density.

The source for the contaminated soil calculations is an infinite isotropic plane source 

of monoenergetic photons of unit strength (1 Bq m-2), located at the air-ground interface or at 

a specified depth in the soil. Again, a human phantom is standing on the soil at the air-ground 

interface. As noted later, the organ dose due to a source in the soil that is uniformly distributed 

from the surface to a specified depth may be readily computed from the doses due to a series 

of plane sources at different depths. The air composition is the same as for the submersion dose 

calculations (see Table II.2). The assumed soil composition is given in Table II.3, and is that 

for a typical silty soil (Jacob et al., 1986) containing 30% water and 20% air by volume. The 

soil density was taken to be 1.6 × 103

 kg m-3. It should be noted that the radiation field above 

the air-ground interface can, in some circumstances, be scaled to account for differences in soil

surrounding the phantom location.

density (Beck and de Planque, 1968; Chen, 1991). While the radiation field above the air-ground 

interface is relatively insensitive to soil composition for a plane surface source (Beck and de 

Planque, 1968), this is not true for distributed sources within the soil, as we later show.

The source for the water immersion calculations is an infinite pool of water containing a 

uniformly-distributed monoenergetic photon emitter of unit strength (1 Bq m-3). A human phantom 

is assumed to be completely immersed in the pool. The water density is 1.0 × 103

 kg m-3 and the 

composition by mass fraction is 0.112 for H and 0.888 for O; i.e., pure water. 

The radiation field from a semi-infinite cloud source 

The dose near the air-ground interface from a semi-infinite cloud source has been taken to 

be one-half that due to an infinite cloud source, following the practice of Dillman (1974), Poston and 

Snyder (1974), and Kocher (1981, 1983). This has been shown (Ryman et al., 1981) to be a good 

approximation for air dose (within 20%) at energies of 20 keV or greater. At energies below 10 keV 

(the lowest energy considered here), the dose at the interface should still be one-half that due to an 

infinite source, but there will be an increase in dose with increasing height along the phantom. The 

mean free path of these photons is so short that the upper portions of the phantom are effectively 

exposed to an infinite source. Between 10 and 20 keV, there will be some increase in dose with 

increasing height, but since the increase over the dimensions of the body should be fairly small, it 

has not been considered here. 
14


Given this approximation, the radiation field may be computed as that due to an infinite 

cloud source of a monoenergetic photon emitter. In this case, the transport equation (4) loses its 

dependence on spatial position and angle, and may be written, for scattered photons, as (Dillman, 

1970, 1974) 

f (E   

) μ( E  ) s ( E  ) K ( E 

, E0 ) E0 f ( E ) K ( E , E ) dE , (7) E 

where 

μ( E 

) = the linear attenuation coefficient of air at energy E 

; 

f (E 

) dE  = the number of photons per initial photon with energy in dE  about E 

; 

and 

K(E 

, E0) = the probability per unit energy that a photon of initial energy E0 will 

scatter and give rise to a photon of energy E 

. 

The scattered photon fluence is just 

SV × f ( E ) s ( E )  , (8) μ( E ) 

where SV is the source strength per unit volume. The uncollided fluence is easily shown to be 

SV u ( E0 )  . (9) μ( E0 ) 

An updated version of the PHOFLUX computer program, developed by Dillman (1974) to solve this 

Volterra-type integral equation, was used to compute the energy spectrum of scattered photons in 

an infinite cloud source as well as the intensity of uncollided photons. Photoelectric and pair 

production cross section data were taken from ENDF/B-V (Roussin et al., 1983). Klein-Nishina 

scattering cross sections were computed analytically. The resulting energy spectrum from a 100 keV 

source is shown in Fig. II.3. The discontinuity seen in the figure occurs at the minimum possible 

energy to which an initial photon may scatter. The slight bump corresponds to the minimum possible 

energy for a twice-scattered initial photon. 

The radiation field from an infinite water source 

In this case, no approximation to the source is necessary, and Eq. (7) above is directly 

applicable. The PHOFLUX program with ENDF/B-V cross sections was also used here to compute 

the energy spectrum of photons in an infinite water source. The resulting energy spectrum from a 

100 keV source is presented in Fig. II.4.

The radiation field from contaminated soil sources 

In this case, the solution to the transport equation (4) is a function of only one spatial 

and one angular variable. It can be seen from Eq. (4) that the transport equation is linear with 

 ̄  ̄ respect to the source term S (  ̄r, E ,). Therefore, the fluence (  ̄r, E ,) due to an isotropic 

infinite source uniformly distributed over a finite depth in the soil may be determined by 

superposition of the fluence for a series of isotropic infinite plane sources in soil. 

The radiation field due to isotropic infinite plane sources at twelve energies from 0.01 

to 5.0 MeV was computed for source depths of 0, 0.04, 0.2, 1.0, 2.5, and 4.0 mean free paths 

in soil (specified at the source energy). These depths were chosen to facilitate an accurate 

integration during the determination of the dose coefficients for sources uniformly distributed 

over specified depths. The uncollided angular photon fluence was computed analytically. A 

spatial-, energy-, and angular-dependent first collision source was generated from the 

uncollided angular fluence and the cross sections for scattering from the source energy into a 

series of energy groups. The scattered photon fluence due to the first-collision source was 

computed using the one-dimensional multigroup discrete ordinates method (Bell and Glasstone, 

1970). Seventy energy groups between 5.3 and 0.00865 MeV were used. The group boundaries 

were selected to satisfy two criteria: (1) a relatively narrow group was present about each source 

energy of interest, and (2) photons scattering from any group could scatter to at least two other 

groups. A subset of the 70 groups was used for each source energy. The highest energy group 

was just that group containing the source, and the lowest group was that containing the lowenergy cutoff, determined by s + 14, where  is the Compton wavelength (electron rest mass s 

energy divided by photon energy) at the source energy. Since, by conservation of energy and 

momentum, the maximum change in Compton wavelength is 2 for a single scatter, a low-energy 

cutoff corresponding to s + 14 ensures that a minimum of seven scatters is considered. Beck 

and de Planque (1968) state that a low-energy cutoff of s + 13.2 included over 99% of the 

energy deposited in their air-dose calculations, except for the combination of very high source 

energies and very large interface-to-detector distances, which is not of interest here. The only 

exception to our use of the low-energy cutoff was for the 10 keV sources, in which case only 

6 groups were used. At this energy, most photons are immediately absorbed, due to the high 

photoelectric cross section, and the scattered photon fluence decreases quite rapidly with 

decreasing energy. 

In all calculations, the thickness of the air medium was three mean free paths (at the 

source energy). Photons scattered in the atmosphere at a height greater than three mean free 

paths must have traveled a minimum of six mean free paths from the source plane to reach the 

phantom location, and therefore cannot make a significant contribution to organ dose. For the 
17


plane sources at depths of 0, 0.04, 0.2, and 1.0 mean free paths, the thickness of the soil 

medium was taken as three mean free paths (at the source energy). For the sources at depths of 

2.5 and 4 mean free paths, the soil thicknesses were taken as 3.5 and 5 mean free paths, 

respectively. As in the case of air, photons scattered at depths beyond the lower soil boundary 

would have to travel a minimum of six mean free paths from the source plane to reach the 

phantom location, and thus make no significant contribution to organ dose. 

In transport problems involving an isotropic plane source, the angular fluence has a 

singularity at the source plane for directions parallel to the plane (Fano et al., 1959) which 

cannot be accommodated by the discrete ordinates formulation used here, and which can also 

cause problems when the Monte Carlo method is used. To avoid the numerical problems 

associated with the singularity, the uncollided angular fluence is computed analytically. Then, 

a first-collision source; i.e., a distributed source based on the spatial, energy, and angular 

distribution of photons produced by the first collision of source photons, is calculated from the 

analytic uncollided angular fluence. In photon transport, a collision which leads to secondary 

photons can include pair production as well as Compton scatter. The first-collision source, 

averaged over the spatial mesh cells of the discrete ordinates formulation, is taken to be the 

source term in the transport equation, which is solved for the angular fluence of scattered 

photons. Cell-averaged angular first-collision sources have no singularities, even in cells 

adjacent to the source plane. It should also be noted that the scattered angular fluence has a 

singular component at the source plane, and, at short distances from the source, will have 

components of large magnitude in directions nearly parallel to the plane. It has been 

demonstrated (Ryman, 1979) that discrete ordinates calculations for the scattered fluence due 

to a first-collision source must use an angular mesh which has several directions nearly parallel 

to the source plane. Failure to do so will give rise to scalar fluences that are depressed or 

enhanced in a physically unrealistic manner in regions near the source. It is also well known 

(Bell and Glasstone, 1970) that for plane geometries, the fluence near an interface is better 

represented when the angular quadrature directions are chosen from a double-PN Gauss 

quadrature set. Therefore, a DP15 quadrature set with 32 directions was selected for these 

calculations. 

A discrete ordinates solution of the transport equation in which the cross sections are 

represented by truncated Legendre polynomial expansions can give rise to physically unrealistic 

negative angular fluences, due to the negative oscillations in the cross section expansions. This 

problem is worse for highly anisotropic sources, narrow energy groups, and highly anisotropic 

scatter, e.g., Compton scatter of photons. Several studies have demonstrated (Odom and 

Shultis, 1976; Mikols and Shultis, 1977; Ryman, 1979) that this problem may be eliminated 
18


by the use of the exact-kernel cross section representation, i.e., use of a discrete scattering 

matrix rather than a polynomial representation. In this work, a one-dimensional multigroup 

discrete ordinates code (KSLAB1), developed by one of the authors (Ryman, 1979), which uses 

the exact-kernel representation of group-to-group transfer cross sections, was used to perform 

the radiation field calculations. The group-to-group transfer cross sections, which included 

Compton (Klein-Nishina) scattering and the production of annihilation radiation, when 

appropriate, were generated from the data of Biggs and Lighthill (1968, 1971, 1972a, 1972b). 

The spatial mesh in the air and the soil was tailored to each problem to ensure that (1) negative 

angular fluences were not generated as a result of a too-coarse mesh spacing, and (2) the 

angular fluence had converged with respect to mesh size. 

The accuracy of the solutions was checked by comparing the energy and angular 

dependence of the air kerma (i.e., dose to air) 1 m above a 1.25 MeV plane source at the airground interface with the calculations of Beck and de Planque (1968) and with the calculations 

and measurements given in the Shielding Benchmark Problems report (Garrett, 1968). Excellent 

agreement was found in both cases. 

The angular dependence of the air kerma one meter above the air-ground interface is 

shown in Figs. II.5 through II.8 for 100 keV sources at various depths. The ninety-degree angle 

corresponds to radiation incident from the horizon. In these figures, one should note the relative 

importance of the scattered and unscattered components of the kerma and the changes in the 

angular distributions with increasing depth. 

Organ dose from an isotropic field 

The radiation fields for the submersion and water immersion sources are isotropic, 

neglecting the small effect on the incoming angular current caused by the presence of the 

phantom. The organ dose due to an isotropic field was computed using the continuous energy 

Monte Carlo photon transport code ALGAMP (Ryman and Eckerman, 1993), which is an 

updated and combined version of the original ALGAM (Warner and Craig, 1968) and 

BRHGAM (Warner, 1973) codes incorporating the Cristy phantom series (Cristy and Eckerman, 

1987). As described in Appendix B, a modified version of the adult hermaphrodite phantom 

was used for this work. Organ doses in ALGAMP are estimated by scoring energy deposition 

in all organs except skeletal tissues. A collision-density fluence estimator for the skeleton is 

combined with fluence-to-dose conversion factors for active marrow and bone surface 

(Eckerman, 1984; Eckerman and Cristy, 1984; Kerr and Eckerman, 1985, 1987) to estimate 

doses for those organs.

Calculations were performed for twelve monoenergetic sources ranging from 0.01 to 

5.0 MeV. These were carried out using a cosine current source, which corresponds to an 

isotropic fluence, sampled uniformly on the curved and end surfaces of a cylinder surrounding 

the phantom. Ten million histories were sampled for each calculation. The organ doses from 

the monoenergetic sources incident on the phantom were folded with the spectra generated by 

the PHOFLUX code for the air submersion and water immersion sources and normalized to unit 

source strength to produce the final organ dose coefficients for monoenergetic sources in 

contaminated air and water, presented in Tables II.4 and II.5. The coefficients include those for 

effective dose equivalent (hE), effective dose (e) using the ICRP 60 weighting factors, and air 

kerma (kAIR) or water kerma (kWATER). Note that air kerma and water kerma are doses to air and 

water, not to tissue free in air or water. Since the dose coefficients are inversely proportional 

to the density of the source medium, scaling to a different density is straightforward. 

Organ dose from contaminated soil 

The uncollided and scattered angular fluences from an isotropic plane source of 

radiation were computed as a function of energy, angle, and height above the air-ground 

interface as described earlier. These fluence data were used to construct an angular current 

source on a cylinder surrounding the phantom as a function of position, energy, and polar angle. 

It may be noted that the angular current is given by the relationship j (  ̄r, E ,  ̄ )   ̄ nˆ(  ̄r, E ,  ̄ ) 

where nˆ is the outward-directed normal to the surface. For the top and bottom surfaces of the 

 ̄ cylinder, the construction of the angular current source is obvious, since nˆ is just the 

absolute value of the polar angle used in the discrete ordinates calculations. On the side of the 

 ̄ cylinder, nˆ is not an angle used in the calculations. Saito et al. (1990) developed two 

approximations for the relationship between the angular fluence and the current, but no 

approximation is necessary. The angular fluence is isotropic with respect to an azimuthal angle 

about the normal to the source plane, due to the symmetry of the one-dimensional radiation 

field, so the angular current, as a function of polar angle, can be computed analytically from 

the angular fluence data. 

A calculation of organ doses was performed using ALGAMP (Ryman and Eckerman, 

1993) for each of the 72 combinations of source energy and plane source depth, sampling the 

photon energy, angle, and position from cumulative distribution functions corresponding to the 

angular current sources described above. As for the calculations for isotropic sources in air and 

water, ten million histories were generated for each calculation. Since the discrete ordinates 

calculations were performed for a first-collision source generated by a unit strength plane 

source, the organ dose coefficients are computed directly by the Monte Carlo calculations; no 
22


further normalization is needed. For the 10, 15, and 20 keV sources (primarily at 10 keV), a few 

of the organ dose coefficients were estimated to be zero, since low-energy photons are not very 

penetrating, and small organs (e.g., ovaries) are often missed by those few photons which do 

penetrate the body to that depth. For a few organs, the coefficients of variation were so large 

that their dose coefficients were judged to be unreliable. The dose coefficients for those organs 

were also set to zero. However, the procedure described below for integrating organ dose 

coefficients for plane sources over source depth to obtain dose coefficients for volume sources 

involves the logarithm of the dose coefficients; therefore, dose coefficients cannot be zero. Even 

had there been no numerical difficulties, the prudent approach was to assign nonzero values to 

all dose coefficients. Therefore, in the tabulations for monoenergetic sources, the zero values 

were replaced by values from a log-log extrapolation as a function of source energy. The 

dependence of the organ dose coefficients on energy shows this to be a conservative approach. 

As a practical matter, the values of the dose coefficients obtained by extrapolation are so small, 

compared to the dose coefficients for the other organs, that they have no observed influence on 

the coefficients for effective dose equivalent. 

The organ dose coefficients for isotropic plane sources at the six source depths were 

integrated over source depth to compute organ dose coefficients for uniformly distributed 

volume sources having thicknesses of 1, 5, and 15 cm, and for an effectively infinite source 

(4 mean free paths thick). If hˆ

T,P (E,) is the dose coefficient (Sv per Bq s m-2) for tissue T for 

a plane isotropic source at energy E and depth  (mean free paths), then the dose coefficient hˆ

T,L (E) 

(Sv per Bq-s m-3) for a volumetric source extending from the air-ground interface to depth 

L (cm) is just

where μ is the linear attenuation coefficient for soil at energy E. The dose coefficients for each 

organ hˆ

T,P (E,) at the six source depths were interpolated on a fine grid using a log-linear 

Hermite cubic spline (Fritsch and Carlson, 1980). The interpolated data were then numerically 

integrated. The organ dose coefficients are presented in Tables II.6 through II.11 for plane 

sources at the six source depths, and in Tables II.12 through II.15 for the four volumetric 

sources. The coefficients for the plane sources do not need to be scaled for different soil 

densities, since depths are in mean free paths. Coefficients for a source with finite thickness 

expressed in cm cannot be scaled. Coefficients for a source with finite thickness expressed in 

mean free paths are inversely proportional to soil density, as shown by Chen (1991), as are 

those for an infinitely thick source.

Discussion 

In this section we compare our results for effective dose equivalent to published results 

of other researchers. Unless specifically stated otherwise, all values of effective dose equivalent 

discussed in this section are normalized to air kerma free in air, at a distance of one meter above 

the air-ground interface, or to water kerma free in water within an infinite pool. 

Effective dose equivalent, as a function of energy, is shown in Fig. II.9 for an isotropic 

plane source at the air-ground interface, for submersion in a semi-infinite cloud source, and for 

immersion in an infinite water pool, as calculated for this report. In previous calculations 

performed at ORNL (DOE, 1988; Kocher, 1981, 1983; Kocher and Sjoreen, 1985), normalized 

organ doses for a plane surface source and for water immersion were assumed to be those for 

submersion in a semi-infinite cloud. Values of effective dose equivalent for a plane isotropic 

surface source and for water immersion are compared to those for submersion in Fig. II.10. For 

water immersion, the differences are small (less than 10 percent), and are due solely to 

differences in the photon spectra in water and air (see Figs. II.3 and II.4). However, the 

differences for a plane surface source can be as large as 33 percent, and illustrate one of the 

primary reasons that new calculations were performed. 

Effective dose equivalent for submersion in a semi-infinite cloud source, from Table II.4, 

is compared to that from Zankl et al. (1992) at the Gesellschaft für Strahlen- und 

Umweltforschung (GSF), in Figs. II.11 and II.12. Comparisons for an infinite plane isotropic 

source at an effective depth of 0.5 g cm-2 are shown in Figs. II.13 and II.14. The values for the 

upper curve were derived by interpolation, using a log-linear Hermite cubic spline fit to the data 

of Tables II.6 to II.11. The different values are traceable to differences in the adult 

hermaphrodite phantom used in this work and the gender-specific phantoms used at GSF, and 

will be explained in detail later. 

Effective dose equivalent for an infinite plane isotropic source at the air-ground interface 

is shown in Fig. II.15, as derived by two different procedures. The lower curve in Fig. II.15 

shows values from Table II.6. The upper curve represents values derived using fluence-to-dose 

equivalent conversion factors for rotational normal beam exposure (ROT) computed for the adult 

hermaphrodite phantom of Cristy (Cristy and Eckerman, 1987), which was used throughout this 

work. The two curves illustrate the difference due to assuming all photons are normally incident 

(upper curve), as compared to using the actual angular distribution of photons on the body (lower 

curve). The differences in effective dose equivalent for plane isotropic sources at the surface and 

at depths of one and four mean free paths are shown in Fig. II.16. It can be seen that the 

differences between the values for rotational exposure and those for the actual field are 

significant, and increase with increasing source depth.

Effective dose equivalent for a plane isotropic source at the air-ground interface is 

compared to Chen (1991) in Fig. II.17. Chen used the rotational fluence-to-effective dose 

equivalent conversion factors from ICRP Publication 51 (ICRP, 1987) to compute dose 

equivalent for exposure to contaminated soil. Effective dose equivalent computed from the 

photon spectra of this work, using the same ICRP 51 rotational conversion factors as Chen, is 

seen to be in excellent agreement with his values. Figure II.18 shows the difference between the 

values from Table II.6 and the values based on rotational exposure of Fig. II.15, as compared to 

Chen's values. Effective dose equivalent for the adult Cristy phantom is compared to the ICRP 

Publication 51 data (ICRP, 1987) in Figs. II.19 and II.20. The ICRP 51 data were computed at 

GSF (Williams et al., 1985). A comparison of individual organ dose equivalent conversion 

factors which contribute to the effective dose equivalent differences are shown in Table II.16. 

The differences seen in Figs. II.19 and II.20 are due to the same factors that contribute to 

the differences seen in Figs. II.11 to II.14. The organ dose coefficients computed here use the 73 

kg hermaphrodite phantom of Cristy (Cristy and Eckerman, 1987). At GSF, organ dose 

coefficients were computed separately for adult male and female phantoms (Williams et al., 

1985; Zankl et al., 1992). Prior to calculating effective dose equivalent coefficients, the organ 

dose coefficients for the male and female phantoms were averaged, and the ICRP 26 weighting 

factors were applied to the arithmetic mean of the male and female organ dose coefficients. The 

GSF 59 kg female phantom is smaller than the 70 kg male phantom. The female has a height of 

160 cm, a body width of 37.6 cm, and a body depth of 18.7 cm, as compared to 170 cm, 40 cm, 

and 20 cm, respectively, for the male phantom (Saito et al., 1990). Therefore, organ dose 

coefficients will tend to be greater for internal organs of the female phantom, since there is less 

shielding from photons incident on the body surface, and the gender-averaged coefficients used 

in computing the effective dose equivalent will be higher than those derived from the 

hermaphrodite phantom, all other factors being equal. The dose equivalent for remainder in the 

male and female from Williams et al. (1985) in Table II.16 illustrate the tendency for female 

organ doses to be higher for deeply-seated internal organs. The differences in doses to other 

organs do not always exhibit this tendency because they are more directly affected by gender 

differences (e.g., ovaries versus testes) or are more distributed in nature (e.g., red marrow and 

bone surfaces). Comparison of organ doses between the hermaphrodite phantom of this work 

and the GSF phantoms shows that competing factors contribute to the differences in effective 

dose equivalents. The doses to red marrow, bone surface, and thyroid are consistently higher in 

the hermaphrodite phantom. The differences in red marrow and bone surface doses are due 

to different methods of estimating those doses. In the hermaphrodite phantom,

heterogeneity of the marrow and endosteal tissue structures are used to estimate doses. In the GSF 

calculations, the marrow dose is estimated by a mass-weighted partitioning of the dose to skeleton, 

with a correction for the difference in energy absorption coefficients between skeleton and marrow, 

and the skeletal dose is taken as a surrogate for bone surface dose. The thyroid doses in the 

hermaphrodite phantom are higher because the neck region, modified for this work, provides less 

shielding than the neck region of the GSF phantoms. There are also differences in doses to the 

remainder organs. The reasons for these differences are difficult to quantify, since data for all the 

organs which contribute to the remainder have not been published by GSF. However, one difference 

may be that in this work, "remaining tissue" was used as a surrogate for muscle, and was included in 

the list of organs which can contribute to the remainder. It appears that muscle was not included in 

the list for the GSF calculations. In using the hermaphrodite phantom for internal emitters, it has been 

the practice to assign the gonadal tissue the higher dose of either the testes or the ovaries. We have 

continued that practice here; which, for external radiation, means the dose to testes is used, since it is 

always higher than the dose to ovaries. Since the gonadal dose has a high weighting factor (0.25), it 

has a large influence on effective dose equivalent. The combination of the competing effects is clearly 

illustrated in Fig. II.20. At higher photon energies (above 100 keV), photons are relatively penetrating, 

so the dose to the ovaries, in the female, is not much lower than the dose to the testes, in the male, and 

the lower gonadal average dose is compensated for by the increase in average dose to other organs. 

In the energy range from 100 keV down to 15 keV, the ovaries receive significantly more shielding 

than the testes, and the lower gonadal dose more than compensates for the increase in average dose to 

other organs, resulting in a noticeably lower effective dose equivalent than is computed for the 

hermaphrodite phantom. Finally, at the lowest energy (10 keV), the shielding of the testes in the male 

phantom increases significantly, and the difference in dose between the male and female phantoms is 

again not as large. At 10 keV, the average doses to other organs of the male and female phantoms now 

dominate the effective dose equivalent, and are larger than those for the hermaphrodite phantom. 

Therefore, the effective dose equivalent for the hermaphrodite phantom at 10 keV is lower than that 

for the average of the GSF phantoms. 

The effective dose equivalent for exposure to an infinite volume source in the soil is compared 

to the work of Chen (1991) in Fig. II.21. Since Chen used the ICRP 51 rotational fluence-to-dose 

equivalent conversion factors, the differences in the phantoms discussed above also explain part of the 

differences shown in this figure. In addition, there is some difference attributable to the use of 

rotational exposure factors instead of the actual angular distributions

used in this work, as shown in Fig. II.15. However, when the dose equivalent is not normalized to 

air kerma, there remain significant differences between the results of this work and those of Chen. 

It has been determined that these differences, which are present for all volumetric sources in the soil, 

are due to use of different soil compositions. The effect of soil composition was investigated by 

computing air kerma 1 m above the air-ground interface for a series of uniformly distributed, 

isotropic, 10 cm thick volume sources at the air-ground interface, for slabs of varying soil 

compositions. The calculations were performed for the 12 source energies used for the 

monoenergetic environmental photon sources, using a one-dimensional Monte Carlo transport code 

based on the ALGAMP transport routines (Ryman and Eckerman, 1993). The soils used in the 

calculations were (a) a dry sandy soil similar in composition to Nevada Test Site soil (Garrett, 1968), 

(b) the typical silty soil used in this work, (c) a soil composed of the average components of the 

earth's crust (Chen, 1991), and (c) Nipe clay soil, a ferruginous laterite soil with a high concentration 

of iron (Lawton, 1955). The volume fractions of air and water in the Nipe clay were assumed to be 

0.2 and 0.3, respectively. All soils were assumed to have a density of 1.6 × 103

 kg m-3. The 

compositions of the soils are given in Table II.17. The air composition is given in Table II.2, and 

is the same used throughout this work.

In the Monte Carlo calculations, the thickness of the air above the interface was three 

mean free paths (at the source energy). The soil depth was the greater of one mean free path 

beneath the 10 cm slab source or three mean free paths plus 5 cm. 

The effect of soil composition is shown in Fig. II.22, which shows air kerma 1 m above 

the 10 cm slab source, normalized to the air kerma 1 m above typical silty soil. It is seen that the 

air kerma at low energies is strongly influenced by the composition, with lighter soil (in terms of 

average atomic number) producing a greater kerma, and heavier soils resulting in a lower 

kerma. The curve for earth's crust explains the remaining differences between the

results of this work and those of Chen (1991). The shape of the curves is explained by Fig. II.23, 

which gives the ratio of the linear attenuation coefficient for silty soil to that of the other soils. 

Although not shown, the ratios of the uncollided contribution to the kermas of Fig. II.22 lie exactly 

on the curves of Fig. II.23. 

In summary, the discussion above illustrates the sensitivity of the dose coefficients to certain 

features of the computational models. For example, the coefficients at lower photon energies are 

sensitive to the elemental composition of the soil. Differences in the treatment of energy deposition 

in red marrow and bone surface are evident in the coefficients for those radiosensitive tissues of the 

skeleton. The effective dose equivalent coefficient is sensitive, again at the lower photon energies, 

to the choice of an anatomical model; i.e., to the use of a hermaphrodite phantom versus the 

averaging of doses from gender-specific phantoms. For the purpose of establishing dose coefficients 

for use in radiation protection, the choice of an anatomical model appears to be more of a public 

policy than a technical issue. We have continued the traditional use of a hermaphrodite phantom, 

as specified in current Federal guidance for workers (EPA, 1987).

silty soil used in this report to that of other soils. 

Many of the features of the computational models interact in a complex manner, making 

an a priori assessment of their contributions to the dose coefficients difficult to assess. The 

analyses of the computational models used to produce this report have been sufficiently detailed 

to account, we believe, for the dependence of the dose coefficients on all significant features 

of the models. The resulting tabulations of coefficients reflect the current state of the art in 

environmental dosimetric calculations. 

Skin doses from monoenergetic environmental electron sources 

In this section we discuss the calculation of the skin dose from electrons for air 

submersion, water immersion, and ground-surface and volume exposures. The contribution of 

electrons to dose to organs and tissues of the body other than skin need not be considered, due 

to the short range in tissue of electrons emitted by radionuclides. However, bremsstrahlung 

produced by electrons slowing down in environmental media are sufficiently penetrating to 

contribute to the dose to underlying tissues. Bremsstrahlung production is discussed in 

Appendix C. The DOSFACTER code developed by Kocher (DOE, 1988) was used to calculate 

skin dose coefficients for a series of monoenergetic electron emissions, that were convoluted 

to the spectra of the various radionuclides, using the energy and intensity of beta and electron 
49


emissions of radionuclides tabulated in ICRP Publication 38 (ICRP, 1983; Eckerman et al., 

1993). The discussion of the computational details, presented below, is taken from that of 

Kocher (DOE, 1988). 

Immersion in contaminated water 

For immersion in an infinite, uniformly contaminated water medium, the skin dose 

coefficient at a depth of 70 μm, for a unit concentration of a monoenergetic electron emitter of 

energy E, can be expressed as 

E ,  (11) hskin(E ) R w(E ) q (E ) Gskin(E ) 

w 

where  is the density of water, Rw

 is the ratio of the energy absorption in tissue to energy w

absorption in water at energy E, q is a leakage correction factor, and Gskin is a geometrical 

reduction factor defined as the ratio of the absorbed dose at the depth of interest into a semiinfinite tissue medium to the absorbed dose in the contaminated water for the energy E. The 

energy-absorption ratio Rw

 is obtained from the mass stopping powers, 1 dE in tissue (t) and 

 dx water (w) as 

1 dE 1 dE R w (12)  / .  dx  dx t w 

Since the stopping powers in tissue and water are nearly independent of energy, the ratio in 

Eq. (12) is evaluated at the emitted energy. The mass stopping powers in tissue and water used 

in the DOSFACTER code were those reported in National Academy of Sciences-National 

Research Council Publication 113 (NAS, 1964). 

The geometrical reduction factor Gskin relates the dose to skin (at a depth of 70 μm) to 

the dose in water. This factor is obtained from electron specific absorbed fractions in water 

calculated using Monte Carlo methods, as described by Berger (1974). In calculations of the 

geometrical reduction factors it is assumed that a half-space occupied by water (as a surrogate 

for tissue) is in contact with a uniformly-contaminated half-space containing water (the source). 

Thus, Gskin has a value of one-half at the interface (i.e., the body surface) and decreases with 

increasing depth into the body. The geometrical reduction factors used in the present 

calculations were derived by Berger (1974). 

The leakage correction factor q accounts for the finite lateral extent of the body surface 
50


and is given by the empirical formula (Berger, 1974) 

q(x, E ) 1 q1(E ) q2(x/a),  (13)

h

where x is the depth of interest, here taken as 70 μm, and the parameter a depends only on the 

emitted energy E. Values of q1, a, and q2 used in the DOSFACTER code were those given by 

Berger (1974). The DOSFACTER code was used to tabulate the dose coefficient for the skin, 

skin (dose per unit volume source), in water. The results are shown graphically in Fig. II.24. 

Fig. II.24. Electron skin dose coefficient for immersion 

in contaminated water. 

Submersion in contaminated air. 

For an exposed individual standing at the boundary of a semi-infinite, uniformly 

contaminated atmospheric cloud, we assume that the electron range in air is less than the 

average height of the body, which is taken to be 1 m. Therefore, the source region is assumed 

to be effectively infinite in extent, and the electron dose coefficient at the depth of interest into 
51


tissue (70 μm) is given in terms of the geometrical reduction factor Gskin for immersion in 

contaminated water, noted above, as (Berger, 1974) 

R a 

hskin(E )  E

q(x,E ) Gskin(E ), (14) 

 a 

where a is the density of air, Ra

/is the ratio of energy absorption in tissue to that in air at the 

emitted energy E, and the leakage correction factor q and the geometrical reduction factor Gskin 

are as discussed above. 

The energy-absorption rate Ra

/consists of two factors. The first factor is the ratio of 

the mass stopping powers in tissue and air (NAS, 1964): 

R a  1 



dE

/ 1

, (15) 

which is evaluated at the emitted energy E. The second factor, , also depends on the emitted 

energy and accounts for the variations in mass stopping powers in tissue and air over the 

continuous energy spectrum of electrons incident on the body for a monoenergetic source of 

energy E in an infinite, uniformly-contaminated atmospheric cloud (Berger, 1974). Dose 

coefficients for skin calculated using the DOSFACTER code for submersion are shown in 

Fig. II.25. 

Fig. II.25. Electron skin dose coefficient for submersion in 

contaminated air. 
52


Exposure to contaminated soil 

The geometrical reduction factor Gskin identified above cannot be used to calculate skin 

dose coefficients for exposure to contaminated soil, since it applies only to the situation where 

the source region occupies one half-space and tissue the other. Therefore, the coefficients for 

exposure to contaminated ground must be obtained by explicit consideration of the radiation 

transport. 

In the calculations performed by DOSFACTER, the transport of energy through air and 

into the body was reduced to consideration of an equivalent thickness in air alone. Thus, for 

a height z of the body surface above the ground and depth x into the body, the effective height

z 

 in air above the ground is given by 



z   z  1.14 t (16) x , a 

where t and a are the densities of tissue and air, respectively, and the factor 1.14 approximates 

the ratio of mass stopping powers in tissue and air for any electron energy (NAS, 1964). 

The electron dose coefficient for skin at the height z  in air above ground defined by 

Eq. (16) then is given by 

1 hskin(E )  2 

E R a 

a (r, E ) d , (17) 

where Ra

 is the ratio of mass stopping powers in tissue and air evaluated at the emitted energy 

E,  denotes the ground surface, a

 is the specific absorbed fraction for electrons in air, and 

r is the distance from any point on the ground surface to the receptor located at height z 

 in air 

above the ground. The factor 1/2 accounts for the impenetrability of the body by electrons, so 

that any point on the body surface is irradiated by only half of the source region. 

The DOSFACTER code evaluates Eq. (17) numerically using the electron scaled point 

kernel, F, developed by Berger (1974). The scaled point kernel is defined in terms of the 

specific absorbed fraction  as 

F(r/ro, E ) d(r/r )  4(r, E ) r 2 dr , (18) o

where r0 is the electron range for energy E in a medium of density . Thus, the scaling of the 

specific absorbed fraction is accomplished by expressing distances in units of electron range. 

The DOSFACTER code uses the scaled point kernels in water, Fw, given by Berger 
53


(1973). The scaled point kernels in air, Fa

, are obtained from those for water according to 

Berger (1974) as 

 F a

(r/ro

a 

, E ) 

F w(r/ro

a  , E ), (19)

 where is a scaling parameter that depends on the energy E. By expressing Eq. (17) in terms 

of the scaled point kernel in air, the electron dose coefficient for skin is 

1 E  1 R a  z /ro u

F a h (u , E ) du , (20) skin (E )  a 4r a a o 

a where u is the scaled distance r/r0 . 

The above formulations, as implemented in the DOSFACTER code, are not directly 

applicable to the situation where the source is uniformly distributed within the soil. To 

approximate this situation, an additional term was added to Eq. (16) to convert the depth of a 

planar source into its equivalent air thickness. Because of the limited range of electrons in the 

soil, the source may be regarded as infinitely thick. Calculations were performed for a series 

of planar sources ranging from the surface to a depth beyond the range of the electrons and the 

results for a source distributed in the volume was then approximated by superposition of the 

results for the planar sources. The resulting coefficients for monoenergetic electron emitters 

on the surface and in the volume are seen in Fig. II.26.

contaminated soil.

Dose coefficient formulation for radionuclides 

The energies and intensities of the radiations emitted in spontaneous nuclear 

transformations of radionuclides have been reported in Publication 38 of the International 

Commission on Radiological Protection (ICRP, 1983). That publication, a report of the Task 

Group on Dose Calculations of ICRP Committee 2, was assembled at ORNL during the 

preparation of ICRP Publication 30 (ICRP, 1979). The nuclear decay data of Publication 38 

are based on the Evaluated Nuclear Structure Data Files (ENSDF) (Ewbank and Schmorak, 

1978) of the Department of Energy's Nuclear Data Project as processed by the EDISTR code 

(Dillman, 1980). The processed data files retained in the ICRP/ORNL dosimetric data base 

(Eckerman et al., 1993) include not only the full tabulations of the energies (average or unique) 

and intensities of the radiations, but also the beta spectra. The dose coefficients presented here 

are based on these data. 

When electrons slow down in a medium, a small fraction of their initial kinetic energy 

is converted into energy in the form of photons called bremsstrahlung (from the German word 

for braking radiation). Bremsstrahlung energy is distributed from zero up to the initial electron 

energy. Although the bremsstrahlung yield is rather small (only about 0.2% for a 1.0 MeV 

electron in air), for pure beta emitters it can be the only source of radiations that are sufficiently 

penetrating to irradiate deeper-lying radiosensitive tissues. Appendix C discusses the manner 

in which the bremsstrahlung spectra were evaluated in this work. 

Only photons, including bremsstrahlung, and electrons emitted by the radionuclides are 

sufficiently penetrating to contribute to the dose to tissues and organs of the body. The energy 

spectra of emitted radiations are either (1) discrete, as in the case of gamma emissions, or 

(2) continuous, as in the case of beta particles and bremsstrahlung. The beta spectra, from the 

ICRP/ORNL dosimetric data file, are used here to evaluate the contribution of the beta particles 

to the skin dose and to determine the yield of bremsstrahlung. 

The dose coefficient h S for tissue T for any exposure mode S can be expressed as T

S S  S  yj (Ei ) hˆ

T  , j (Ei ) o 

yj (E ) h

ˆ

T, j (E ) dE (21) 

je, i 

where yj(Ei ) is the yield of discrete radiations of type j and energy Ei

, and yj

(E) denotes the 

yield of continuous radiations per nuclear transformation with energy between E and E + dE. 

The other summation is over all electron and photon radiations. Note that each radiation 

potentially has two components: (1) the discrete energy emissions, and (2) the continuous 

emissions. The contribution of the radiations to the dose in tissue or organ T is defined by the 
55


S 

quantity h

ˆ

T ( E ) which is tabulated as a function of energy for tissue and organ T for each 

exposure mode. In the case of the discrete emissions, a value appropriate to the energy of the 

discrete radiation being evaluated is obtained by interpolation. For photons, these data are 

tabulated for 25 target tissues of the body at each of 12 monoenergetic photon energies, while 

for electrons, values are tabulated only for the skin. 

Relationship to Federal Guidance Report No. 11 

Federal Guidance Report No. 11 (Eckerman, et al., 1988) contains dose coefficients for 

submersion exposure to noble gas radionuclides and elemental tritium. Those data, given in 

Table 2.3 of that report, were based on the dosimetric analysis of ICRP Publication 30 and are 

now replaced by the values in Table III.1 of this report. Below, we briefly discuss some of the 

differences between these two tabulations of dose coefficients. 

The submersion coefficients for elemental tritium (3

H) and 37Ar present in Table III.1 

are taken from Table 2.3 of Federal Guidance Report No. 11. The coefficient for elemental 

tritium is based on the dose equivalent received by the lung due to elemental tritium within the 

airways of the lung after equilibration with the atmosphere. In a similar manner, the coefficient 

for 37Ar is based on the activity in the airways. The elemental form of tritium and the noble gas 

37Ar do not deposit on the airways and thus do not represent an intake by inhalation. They also 

do not emit radiations sufficiently penetrating to irradiate the body as an external source. Note 

that the coefficient in Table III.1 is only for elemental tritium. For tritiated water vapor, the 

inhalation intake should be evaluated using the inhalation coefficients of Table 2.1 of Federal 

Guidance Report No. 11. 

The methods used to compute the submersion coefficients of Table III.1 are an 

improvement upon those used to derive the values in Table 2.3 of Federal Guidance Report 11, 

although the numerical differences in the coefficients, particularly for the effective dose, are 

rather minor. We note the following differences in the computational methods: 

Breast Tissue: In the earlier analysis, breast tissue was not represented in the 

anatomical model used to derive the submersion dose coefficients. The dose coefficient for 

muscle was used as a surrogate for breast tissue. This appears to have slightly underestimated 

the breast dose. The presence of breast tissue does increase the body's shielding of the lungs 

and therefore lowers the dose to the lung at low photon energies. 

Skeletal Tissues: The dose coefficients for the skeletal tissues (red marrow and bone 

surfaces) in this work explicitly consider the deposition of energy in the skeletal tissues of 

interest by the secondary electrons liberated by photon interactions in the skeleton. In contrast, 
56


the earlier calculations assumed that the energy given to secondary electrons was partitioned 

among the various tissues of the skeleton according to their mass fractions. Consideration of 

energy deposition by secondary electrons results in lower dose estimates for the red marrow at 

low photon energies since the electrons are largely liberated by photoelectric interactions in the 

bone mineral and deposit much of their energy in this region rather than in the marrow spaces. 

For example, the 133Xe coefficient for the active marrow in this report is more than a factor of 

three lower than the value in Federal Guidance Report No. 11. 

Thyroid: The anatomical model has been modified to include a neck region and the 

thyroid has been moved to an appropriate position for external dosimetry. These changes 

obviously alter the amount of overlaying tissues shielding the thyroid. See Appendix B for 

further details. 

Radiation Transport: The present coefficients are based on Monte Carlo radiation 

transport calculations with many more histories than the calculations for Federal Guidance 

Report No. 11. The new calculations have substantially reduced the statistical errors that were 

present in the earlier data for some organs of the body.

TABLE III.2 

Dose Coefficients for Water Immersion 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. The coefficients are for water at a density of 1 × 103

 kg m-3 . 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-3), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-3), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to a source per unit mass basis (Sv per Bq s kg-1), multiply table entries by 

1 × 103

 (kg m-3). 

To convert to conventional units (mrem per μCi y cm-3 or mrem per μCi y g-1), multiply 

table entries by 1.168 × 1023. 

To derive coefficients for a water density other than 1 × 103

 kg m-3, multiply coefficients 

(in any units) by (1 × 103

/), where  is the water density in kg m-3.

TABLE III.3 

Dose Coefficients for Exposure to Contaminated Ground Surface 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-2), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-2), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to conventional units (mrem per μCi y cm-2), multiply table entries by 

1.168 × 1021. 

The coefficients are valid for any soil density.

TABLE III.4 

Dose Coefficients for Exposure to Soil Contaminated to a Depth of 1 cm 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. The coefficients are for soil at a density of 1.6 × 103

 kg m-3 . 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-3), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-3), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to a source per unit mass basis (Sv per Bq s kg-1), multiply table entries by 

1.6 × 103

 (kg m-3). 

To convert to conventional units (mrem per μCi y cm-3), multiply table entries by 

1.168 × 1023. 

To convert to conventional units for a source per unit mass basis (mrem per μCi y g-1), 

multiply table entries by 1.868 × 1023. 

Radionuclide dose coefficients for soil contaminated to a finite depth cannot be scaled 

to account for a different soil density.

TABLE III.5 

Dose Coefficients for Exposure to Soil Contaminated to a Depth of 5 cm 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. The coefficients are for soil at a density of 1.6 × 103

 kg m-3 . 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-3), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-3), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to a source per unit mass basis (Sv per Bq s kg-1), multiply table entries by 

1.6 × 103

 (kg m-3). 

To convert to conventional units (mrem per μCi y cm-3), multiply table entries by 

1.168 × 1023. 

To convert to conventional units for a source per unit mass basis (mrem per μCi y g-1), 

multiply table entries by 1.868 × 1023. 

Radionuclide dose coefficients for soil contaminated to a finite depth cannot be scaled 

to account for a different soil density.

TABLE III.6 

Dose Coefficients for Exposure to Soil Contaminated to a Depth of 15 cm 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. The coefficients are for soil at a density of 1.6 × 103

 kg m-3 . 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-3), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-3), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to a source per unit mass basis (Sv per Bq s kg-1), multiply table entries by 

1.6 × 103

 (kg m-3). 

To convert to conventional units (mrem per μCi y cm-3), multiply table entries by 

1.168 × 1023. 

To convert to conventional units for a source per unit mass basis (mrem per μCi y g-1), 

multiply table entries by 1.868 × 1023. 

Radionuclide dose coefficients for soil contaminated to a finite depth cannot be scaled 

to account for a different soil density.

TABLE III.7 

Dose Coefficients for Exposure to Soil Contaminated to an Infinite Depth 

Explanation of Entries 

For each radionuclide, values for the organ dose equivalent coefficients hT , and the effective 

dose equivalent coefficient hE , based upon the weighting factors of Table II.1, are given in 

SI units. The coefficients are for soil at a density of 1.6 × 103

 kg m-3 . 

hT : The tissue dose equivalent coefficient for organ or tissue T (Sv per Bq s m-3), i.e., the dose 

equivalent per unit time-integrated exposure to a radionuclide. 

hE : The effective dose equivalent coefficient (Sv per Bq s m-3), i.e., the effective dose equivalent 

per unit time-integrated exposure to a radionuclide: 

h  . E  wT hT 

T 

Note that skin is not included in the summation. 

To convert to a source per unit mass basis (Sv per Bq s kg-1), multiply table entries by 

1.6 × 103

 (kg m-3). 

To convert to conventional units (mrem per μCi y cm-3), multiply table entries by 

1.168 × 1023. 

To convert to conventional units for a source per unit mass basis (mrem per μCi y g-1), 

multiply table entries by 1.868 × 1023. 

To convert coefficients for a soil density other than 1.6 × 103

 kg m-3, multiply coefficients 

(in any units) by (1.6 × 103

/), where  is the soil density in kg m-3.

IV. APPLICATION CONSIDERATIONS 

In this chapter we discuss some potentially important considerations in applying the 

dose coefficients to obtain realistic estimates of doses to members of the public. Applicability 

of the coefficients to a particular situation is influenced by those exposure conditions that differ 

from the assumptions in the derivation of the coefficients and other factors which might alter 

the radiation field at the location of the exposed individual. For example, the radiation field 

within a residence may be substantially different in energy and angular distribution, as well as 

intensity, from the field outside the residence. Furthermore, radionuclides may not be 

distributed in the environment in the manner assumed in deriving the dose coefficients; e.g., 

the actual distribution in the environment may be nonuniform. Modifying factors have 

historically been used with dose coefficients to estimate the dose for radiation fields which 

depart from idealized fields. Finally, the exposed individual may not conform sufficiently to 

the model of the human body assumed in determining the dose coefficients. 

Environmental factors can influence the time-integrated activity that characterizes 

exposure, and an individual's life style may influence the extent of contact with a radionuclide 

in the environment. For example, the time-integrated activity of a radionuclide in an urban 

environment may be substantially different from that in a rural environment where 

environmental measurements are generally conducted. While these aspects are beyond the 

scope of this report, it is important to note that in prospective assessments the joint influence 

of these various factors is frequently expressed as a single modifying factor. 

Radionuclide decay chains 

In applying the dose coefficients of Tables III.1 through III.7 it is important to note that 

the values for each radionuclide do not include any contribution to dose from radioactive decay 

products formed in the spontaneous nuclear transformation of the nuclide. Rather, the 

tabulations contain separate entries for all such progeny. 

In general, dose coefficients for a radionuclide and its progeny can be combined only 

after proper consideration of the equations describing production and decay of daughter 

radionuclides over time, and differences in environmental behavior of the parent and daughters. 

The information necessary to describe the production and decay of daughters is given in 

Appendix A. 

183

184 

Various simplifying assumptions have often been made when considering radioactive 

progeny following an "instantaneous" deposition of the parent nuclide, i.e., a deposition that 

occurs in a time period which is short compared to the half-life of the radionuclide and to the 

integration time of interest (DOE, 1988; Jacob et al., 1988a). However, such assumptions 

should no longer be necessary, since widespread access to personal computers and workstations 

makes solution of the appropriate equations almost a trivial task. Even for non-trivial time 

dependencies (see Jacob et al., 1988b) up to and including arbitrary deposition and/or removal 

rates, convolution methods can readily be applied to the dose coefficients tabulated in this 

report to estimate dose equivalents. 

Spontaneous fission 

Spontaneous fission is an important decay mode for a few radionuclides in Tables III.1 

to III.7, e.g., 248Cm, 250Cm, 252Cf, and 254Cf. The frequency of spontaneous fission for these and 

other radionuclides is given in Appendix A. Empirical relationships describing the continuous 

energy spectra of photons, electrons, and neutrons from spontaneous fission, as needed in 

dosimetric evaluations, have been reported by Dillman and Jones (1975). However, detailed 

information has not been assembled on the radiation field (both neutron and gamma) resulting 

from distributed sources of neutrons in the environment. Radionuclides with a significant 

spontaneous fission yield are generally not released to the environment, or, if present in the 

environment, are at extremely low concentrations. The coefficients reported here for 248Cm, 

250Cm, 252Cf, and 254Cf do not include any contribution to dose from spontaneous fission and 

might considerably underestimate external dose from these radionuclides. 

Models of the human body 

All organ doses in this report are calculated for an anthropomorphic model of the body 

derived by Cristy (Cristy and Eckerman, 1987) from ICRP Reference Man data (ICRP, 1975). 

The model represents an adult of stature 179 cm and mass of 73 kg. For all calculations, except 

water immersion, the phantom is upright at the air-ground interface. The phantom is a 

hermaphrodite of design similar to that used in the dosimetric evaluation of ICRP 

Publication 30 (ICRP, 1979) and is currently being used in the preparation of the various parts 

of ICRP Publication 56 (ICRP, 1990). Gender-specific models of adults have also been used 

in deriving external dose coefficients; e.g., ICRP Publication 51 (ICRP, 1987). However, most 

calculations of organ dose from the intake of radionuclides are based on the hermaphrodite 

phantom (ICRP, 1979, 1990). 
185


Organ doses for individuals of specific size and gender may be somewhat different from 

the values tabulated here. Gender- and age-specific aspects of external dose have been 

investigated by Drexler et al. (1989) and Petoussi et al. (1991); see also the discussion of organ 

dose coefficients for monoenergetic environmental photon sources in Section II. The dose to 

organs of the body from external radiation increases with decreasing body size. This effect is 

more pronounced at low photon energy, and for organs located near the middle of the body, 

which are shielded by overlying tissues. Petoussi et al. (1991) indicate that organ doses for an 

infant may be about 40% higher than those in the adult male for both the ground plane source 

and submersion exposure at photon energies greater that 100 keV. Below 100 keV the 

difference may approach a factor of 3 for deeper organs such as the ovaries and colon. 

Pathway-specific modifying factors and exposures 

This section discusses modifying factors that can be used with the dose coefficients 

presented in this report to account for the effects of indoor residence, ground roughness, 

exposure during boating activities, and exposure to contaminated shorelines. These modifying 

factors, or dose-reduction factors, are multiplicative factors less than or equal to unity. They 

may be applied when using the tabulated dose coefficients for particular exposure modes to 

obtain more realistic estimates of dose equivalents to members of the public. Much of the 

discussion below is taken from that of Kocher (DOE, 1988). 

Consider the problem of reconstructing the dose to an individual exposed in a number 

of different situations to a radionuclide present in the environment; e.g., while outdoors or 

within a residence. The dose equivalent HT in tissue T due to exposures during the period t1 to 

t2 composed of n different exposure conditions can be expressed as 

t n 2

HT  hT  Si Ri

where Si

 denotes the strength of the radiation field (e.g., kerma in air) for exposure condition 

i relative to the idealized exposure conditions assumed in deriving the dose coefficient hT; the 

function Ri

(t) defines whether exposure condition i is in effect at time t (it is a Heavyside 

function, having a value of 1 at times when condition i is applicable, or else it is zero); and C(t) 

is the time-dependent concentration of the radionuclide in the environmental medium 

responsible for the radiation field. The summation extends over all exposure conditions i. In 
186


prospective assessments, information is usually not available to characterize Ri

(t). Then, 

exposure condition i is assumed, on average, to represent a fraction, R ̄

i , of the exposure period, 

and Eq. (22) reduces to

The factors Si

 and R ̄

i take account of two fundamentally different considerations: (1) the change 

in dose contribution resulting from modification of the radiation field for a particular exposure 

situation; e.g., shielding by a building; and (2) the fraction of the exposure period associated 

with the particular exposure situation. Note that the product of Si and R ̄

i or, in many cases, the 

summation of their products, are often represented by a single modifying factor. Such ad hoc 

factors can be used only for the specific conditions for which they were derived, and should be 

use with extreme caution when the strength of the radiation field is highly time-dependent; e.g., 

following an acute release of short-lived radionuclides to the environment. 

Ground roughness 

The dose coefficients of Table III.3 for exposure to a contaminated ground surface 

assume that the source region is a smooth plane. A more realistic dose assessment for this 

exposure mode would take into account the effects of ground roughness in reducing external 

dose equivalents; i.e., the shielding provided by terrain irregularities and surface vegetation for 

sources on the ground surface. A dose-reduction factor for ground roughness can be applied 

in addition to the dose-reduction factor for indoor residence discussed above. In that case, no 

additional consideration of exposure times is needed in estimating the effects of ground 

roughness on external dose equivalents. 

Dose-reduction factors for a photon spectrum representative of deposited radionuclides 

following releases from nuclear reactors are given by Burson and Profio (1977). The 

recommended values range from essentially unity for paved areas to about 0.5 for a deeply 

plowed field; a representative average value is about 0.7. This average dose-reduction factor 

would overestimate external dose equivalents from ground-surface exposure if the radionuclides 

emit mostly low-energy photons (Kocher, 1980). Jacob et al. (1986) used an effective depth 

of 3 mm into the soil to account for surface roughness. In subsequent work, Saito et al. (1990) 

and Petoussi et al. (1991), expressed the depth in terms of a density thickness of 0.5 g cm-2 
187


(equivalent to 3 mm for a soil density of 1.6 × 103

 kg m-3). Interpolation in the monoenergetic 

source data of Tables II.6 to II.11 indicates that the shielding factor for a source plane at a depth 

of 3 mm is about 0.7 for photons of energy greater than 100 keV. If an appropriate depth can 

be determined for a particular ground surface source, interpolation in the monoenergetic photon 

source dose coefficients of Tables II.6 to II.11 can be used to determine dose coefficients which 

can then be folded over the radionuclide decay data as specified by Eq. (21). 

Electron dose-reduction factors for ground-surface exposure that take into account 

surface roughness have not been treated in the literature. However, some reduction in dose due 

to terrain irregularities and surface vegetation undoubtedly occurs. The electron dose is likely 

to be reduced more than the photon dose due to ground roughness. Furthermore, the electron 

dose will be strongly influenced by the moisture content of the soil and the amount of snow 

cover. Therefore, in estimating electron dose coefficients for ground-surface exposure, it would 

be conservative to use the appropriate photon dose-reduction factors for ground roughness, 

since the resulting electron dose probably would not be underestimated. 

Non-uniform volume source distributions 

For photon exposure, the assumption of uniformly-contaminated slab sources is 

appropriate for frequently plowed soils or for use with linear compartment models that describe 

downward migration of radionuclides in soil (see Sjoreen et al., 1984). It may be appropriate 

to treat volume sources as being non-uniformly distributed when a reasonable approximation 

to the distribution is known. For example, Beck and de Planque (1968) and Kocher and Sjoreen 

(1985) have considered sources exponentially distributed in the soil, which may be appropriate 

for natural infiltration of radionuclides into the soil during a chronic deposition on the surface. 

The dose coefficients for a known distribution of monoenergetic photon emitters can easily be 

derived by integrating the coefficients of Tables II.6 through II.11 over the distribution. Then, 

Eq. (21) can be used to determine the coefficients for the radionuclides of interest. 

External exposure to electrons from radionuclides distributed with depth in soil 

generally can be neglected, because a few centimeters (often, only a few millimeters) of soil 

provides complete shielding of electrons from radioactive decay for a receptor location 1 m 

above ground (NAS, 1964). Therefore, calculations of electron dose equivalents from sources 

deposited on the ground need to consider only those sources that remain on or very near the 

surface. The tabulations of electron dose coefficients for volume sources in this report are 

based on the conservative assumption of an infinitely thick source. 
188 

Contaminated shorelines 

The dose coefficients for exposure to contaminated soil in Tables III.3 through III.7 

assume that the source region is infinite in extent and, thus, are appropriate for large areas that 

are contaminated by deposition of radionuclides from the atmosphere or by irrigation with 

contaminated water. Exposure to contaminated soil may also occur during fishing or hiking 

along shorelines of finite width that are contaminated by deposition of radionuclides from 

water. 

For photon exposure, the NRC (1977) has recommended the following dose-reduction 

factors for different types of shorelines: 

- 0.1 for discharge canal bank; 

- 0.2 for river shoreline; 

- 0.3 for lake shore; 

- 0.5 for ocean shore; 

- 1.0 for tidal basin. 

These values would be applied in addition to the dose-reduction factor for ground roughness 

discussed earlier. They do not include consideration of exposure times. 

Dose-reduction factors for exposure to electrons from contaminated shorelines have not 

been considered in the literature. Due to the relatively short range of electrons in air, the dose 

coefficient from exposure to shorelines of finite width should be about the same as the dose 

coefficient for exposure to an infinite ground surface; i.e., the dose-reduction factor should be 

nearly unity. However, the high moisture content of the shoreline would also reduce the 

electron dose for these exposures. As discussed earlier, an electron dose-reduction factor for 

ground roughness, based on an appropriate value for photons, could be taken into account in 

estimating electron dose coefficients for exposure to contaminated shorelines. 

Although site-specific data for exposure times to contaminated shorelines can be used 

when available, the NRC (1977) has recommended exposure times in lieu of site-specific 

information. The values for an adult are 12 hours per year for maximally exposed individuals 

and 8 hours per year for average individuals in population groups. If other age groups are taken 

into account, the recommended exposure times are higher. For teenagers, the recommended 

values are 67 hours per year for maximally exposed individuals and 47 hours per year for 

average individuals in population groups. 

Exposure during boating activities 

The dose coefficients for immersion in contaminated water in Table III.2 assume 

immersion in an infinite pool and, thus, are appropriate for exposure while swimming. External 

exposure to contaminated water can also occur during boating activities. 
189 

For photon exposure, a dose-reduction factor of 0.5 during boating activities is a 

reasonable value that is unlikely to underestimate external dose equivalents. This dosereduction factor takes into account that the source region is effectively semi-infinite in extent 

for an exposed individual located at the boundary of the air-water interface and assumes that 

the shielding of photons provided by the typically thin hull of a boat is negligible. The latter 

assumption will result in overestimates of external dose equivalents during boating activities 

for radionuclides that emit mostly low-energy photons. 

For electron exposure, it is reasonable to assume a dose-reduction factor of zero during 

boating activities; i.e., that the electron dose equivalent is zero. The hull of a boat should 

provide complete shielding from electron sources in the water. 

The exposure time for boating activities should be estimated on a site-specific basis. 

For individuals who reside on a boat for all or part of a year, an exposure time of 50% or more 

would be reasonable. For individuals who engage only in recreational boating activities, an 

exposure time as high as 5% (44 hours per year) would be reasonable. 

Effects of indoor residence 

The dose coefficients for air submersion and exposure to contaminated soil tabulated 

in Section III relate the organ dose to the time-integrated air or soil concentration, assuming the 

individual is located in the open without the benefit of shielding from structures. To 

realistically assess the dose for these exposure modes, consideration must be given to the 

reduction of the radiation field due to shielding by building structures. 

Following the Chernobyl accident, considerable efforts have been devoted to improving 

the models for assessing external dose from airborne and deposited radionuclides, including 

evaluation of the reduction in the radiation field by various structures. The results of an 

extensive study of the shielding factors for selected European single-family and multi-story 

structures were reported by LeGrand et al. (1991) and Jacob and Meckbach (1991). For an 

airborne plume, the shielding factor (ratio of kerma in the "shielded" position to that in the 

open) ranged from about 0.01 to 0.7 for single family homes. In some cases, it may be more 

appropriate to assume that exposed individuals are residing in basements of homes or in 

schools, apartment houses, or office buildings. These structures generally provide significantly 

greater shielding than living areas in single-family homes. For submersion in contaminated air, 

representative shielding factors range from 0.6 for the basement of a wood frame house to 0.2 

or less for a large office or industrial building. For contaminated soil exposure, representative 
190


shielding factors range from 0.1 for the basement of a home to 0.005 for the basement of large, 

multi-story structures (Burson and Profio, 1977). LeGrand et al. (1991) estimated the shielding 

factor for exposure in multi-story structures to an airborne plume. At a photon energy of 

0.68 MeV, it ranged from 0.01 to 0.1 on the ground floor, and from 0.09 to 0.4 on the upper 

floors which have decreased shielding. 

In an urban setting, for an overhead plume, locations outside of a structure are shielded 

by neighboring structures at a value of about 0.8, which is rather independent of photon energy. 

Within a structure, the dependence of the shielding factor on energy is more pronounced at 

strongly shielded locations like basements and lower floors of multi-floor structures. 

Neighboring structures can also have a large influence (factor of two) on the shielding inside 

of a structure (LeGrand et al., 1991). 

For photon exposures following routine releases from nuclear reactors, the U. S. 

Nuclear Regulatory Commission has recommended (NRC, 1977) the following modifying 

factors for air submersion and exposure to contaminated soil that account for both the shielding 

provided by structures and the fraction of time individuals spend indoors: 

- 0.7 for maximally exposed individuals; 

- 0.5 for average individuals in population groups. 

Both modifying factors are based on a shielding factor of 0.5. It should be noted that the values 

are most appropriate for photon energies above a few hundred keV. For photons of lower 

energy, use of these factors may considerably overestimate the dose equivalent (Kocher, 1980). 

Note that the difference in the two modifying factors implies a different fraction of time spent 

indoors; i.e., about 60% for maximally exposed individuals and effectively 100% for average 

individuals in population groups. In both cases, the individuals are presumed to spend 100% 

of their time at the exposed location. These dose-reduction factors were based on an analysis 

by Burson and Profio (1977). The National Council on Radiation Protection and Measurements 

has recommended similar values (NCRP, 1975), based on a compilation by Oakley (1972). 

For electron exposures, external dose equivalents from electrons during indoor residence 

can be estimated on the basis of concentrations of radionuclides in indoor air and on the floor 

of the building (see Kocher, 1980). Electrons emitted by radionuclides outside the building 

cannot penetrate the structure. 

The following discussion of modifying factors for electrons during indoor residence 

applies primarily to routine (i.e., chronic) releases of radionuclides to the atmosphere, in which 

case steady-state concentrations of airborne radionuclides inside and outside buildings may be 

assumed. For acute releases, however, the relationship between indoor and outdoor airborne 
191


concentrations of radionuclides will vary with time during and after a release, and will also 

depend on the timing and extent of building ventilation. For such releases, it may be prudent 

to assume no reduction in external dose equivalents from electrons during indoor residence. 

For noble-gas radionuclides, air submersion is the only external exposure mode of 

concern. The effects of indoor residence on electron dose equivalents to skin should be 

negligible during chronic releases (i.e., the dose-reduction factor should be essentially unity), 

unless the range of the emitted electrons in air is somewhat greater than the interior dimensions 

of building rooms, because the indoor and outdoor air concentrations for noble gases will be 

about the same. For 85Kr, for example, the electron energies from beta decay are less than 0.687 

MeV and the corresponding electron ranges in air are less than 2.6 m (NAS, 1964), which is 

a representative radius of rooms in single-family homes. Therefore, a dose-reduction factor of 

unity for indoor exposure to electrons from 85Kr decay is reasonable. However, if the electron 

range in air is somewhat greater than the dimensions of building rooms (i.e., if the emitted 

electron energy is about 1 MeV or greater), then the use of a modifying factor of unity will 

overestimate the electron dose equivalent to skin from exposure to noble gases during indoor 

residence. The extent of overestimation depends on the electron range in air relative to the 

dimensions of the building rooms. 

For depositing radionuclides (particulates) dispersing in the atmosphere, the indoor air 

concentration can be considerably less than the outdoor air concentration during chronic 

releases (Kocher, 1980). If the fractional transfer rates from air to surfaces in the indoor and 

outdoor environments are comparable, the dose-reduction factors for external exposure to 

electrons during indoor residence can be substantial for both airborne and deposited activity. 

The dose-reduction factor for electrons for air submersion or a contaminated soil surface can 

be assumed to be equal to the ratio of indoor and outdoor concentrations of airborne or 

deposited radionuclides, respectively, provided the electron range in air is comparable to or less 

than the dimensions of the building rooms. For greater electron ranges in air, this assumption 

again overestimates electron skin dose equivalents during indoor residence, but by unknown 

amounts. 

As stated earlier, indoor residence times recommended by the NRC (1977) for 

maximally exposed and average individuals are 60% and nearly 100%, respectively. In 

prospective assessments, it is generally assumed that both the indoor and outdoor exposures 

occur at the same locations. For a detailed consideration of how people spend their time, see 

Chapter 5 of the EPA Exposure Factors Handbook (1989). That handbook suggests that an 

average young person may spend about 15% of his or her time at school while for an adult it 

may be reasonable to assume a residence time of 25% in office-type buildings. In both cases, 
192


the indoor residence is probably at a location different from the home. Currently the EPA 

Office of Radiation and Indoor Air estimates that on average 75% of the time is spent in the 

home (EPA, 1993). 

Conclusions 

Application of the dose coefficients tabulated in this report typically involves use of 

modifying factors to reflect exposures of different durations to various radiation fields. It was 

the intent of the preceeding discussion to note the nature of the considerations reflected in these 

factors, but it was not the intent to establish specific numerical values for such factors. We note 

that it is extremely useful to keep separate the two aspects of the radiation exposure that are 

reflected in the modifying factors. To reiterate, these are the change in dose contribution 

resulting from modification of the radiation field for a particular exposure situation, and the 

fraction of the exposure period associated with the particular exposure situation; see Eqs. (22) 

and (23). When both these aspects are combined, it is extremely difficult to judge the 

reasonableness of the resulting single factor. We also note that the modifying factors developed 

for prospective assessments of chronic low-level exposures will generally not be applicable to 

exposure following an acute release of radioactivity to the environment. In such cases, the time 

of day of the release and subsequent time dependence of the radiation field can be important 

considerations in determining the dose. The adequacy of any modifying factors applied to the 

dose coefficients tabulated in this report must be determined by the user at the time of the dose 

assessment. 
APPENDIX A 

NUCLEAR DECAY DATA 

The dose coefficients of Tables III.1 through III.7 are listed by radionuclide. In some 

instances a radionuclide is not uniquely identified by its atomic number (or chemical symbol) 

and mass number. Nuclei of the same atomic and mass numbers, but with distinguishable 

nuclear properties, are referred to as isomers. Identification of an isomer requires reference to 

its physical half-life. The nuclide designations of Tables III.1 through III.7 involve some 

nonstandard notation to reference isomers to data in Table A.1 of this appendix. 

To differentiate isomers, when neither isomer has been designated as a metastable state, 

an "a" and "b" have been added to the chemical symbol-mass number notation; e.g., the Nb-89a 

entry in Table A.1 is the 66 m half-life isomer of 89Nb. In Tables III.1 to III.7 the half-life of 

the isomer is given in a footnote. The "a" and "b" notations were assigned to the 89Nb isomers 

in an arbitrary manner. To identify multiple metastable states, the "m" notation of one isomer 

is shown as "n"; e.g., Sb-124m in Table A.1 refers to the metastable state with a half-life of 

93 s while Sb-124n refers to the 20.2 m half-life state. Additional examples can be seen in 

entries of Tables III.1 to III.7 and Table A.1 for indium (In), europium (Eu), terbium (Tb), 

rhenium (Re), iridium (Ir), and neptunium (Np). 

Table A.1 summarizes information on the nuclear decay characteristics of each 

radionuclide considered in this report. All data were obtained from the ICRP/ORNL dosimetric 

data base (ICRP, 1983; Eckerman et al., 1993). Information on the methods used to derive 

these data from the basic nuclear structure information can be found in the report of Dillman 

(1980). 

Table A.1 contains the following information, intended to aid in the proper use of the 

dose coefficients contained in Tables III.1 through III.7. The physical half-life of the 

radionuclides is given in the second column of the table. The time units are abbreviated as: 

y for year, d for day, h for hour, m for minutes, s for second, ms for millisecond, and μs for 

microsecond. The modes of nuclear transformation applicable to the radionuclide are given in 

the column headed "Decay Mode." The modes are abbreviated as: B- for beta minus decay, 

B+ for beta plus decay, EC for electron capture, A for alpha decay, IT for isometric transition, 

and SF for spontaneous fission. The nuclear transformations of a radionuclide (the parent) may 

193

194


form a nucleus which is also radioactive (radioactive decay product). The entries in the 

columns headed by "Radioactive Decay Products and Fractional Yield" identify radioactive 

nuclei formed by nuclear transformations of the parent radionuclide and give the fraction 

(referred to as the branching fraction) of the parent's transformations forming each decay 

product. No attempt is made to identify the radioactive nuclei formed by spontaneous fission. 

The notation "SF" simply indicates that the accompanying branching fraction refers to 

spontaneous fission. The three columns on the extreme right give the total kinetic energy per 

nuclear transformation of emitted alpha particles, electrons, and photons1

. The entry for alpha 

particles represents only the kinetic energy of the alpha particles and does not include the recoil 

energy of the newly formed nucleus. The entry for electrons includes the kinetic energy of all 

beta particles (negatron or positron), internal conversion electrons, and Auger electrons emitted 

in the nuclear transformations. Similarly, the photon entry encompasses gamma rays, x rays, 

and annihilation photons. If nuclear transformations of the radionuclide do not result in 

emission of a particular radiation then a dash, "-", is shown in the appropriate column. If, 

however, radiations of a particular type are emitted, but the total energy per nuclear 

transformation is less than 1 keV, then the symbol "<" appears in the column. 

The dose coefficients of Tables III.1 to III.7 are based on the radiations emitted by the 

indicated radionuclide and do not include consideration of the radiations emitted by radioactive 

decay products. For each radionuclide, the radioactive decay products, if formed, are identified 

in Table A.1. Consider the radionuclide 144Ce. The 144Ce entry in Table A.1 indicates that 144Ce 

has a half-life of 284.3 days and forms 144Pr in 98.22% of its transformations and 144mPr in 

1.78% of its transformations. The entry for 144mPr, half-life of 7.2 m, indicates it decays (in 

99.99% of the transformations) by internal transition to 144Pr; the remaining transformations 

form the stable nucleus 144Nd. Nuclear transformations of 144Pr, half-life of 17.28 minutes, do

The total kinetic energy of radiation type R, ET,R , is computed as 

n 

ET, R   yi , R Ei , R , i1 

where yi,R is the mean number of radiations of type R emitted per nuclear transformation with 

unique or mean energy Ei,R. The quantity should not be confused with the mean energy of 

radiation type R, which is

not form a radioactive decay product. Thus, by repeated entry into Table A.1 one can follow 

the serial transformations (decay chain) associated with a radionuclide. For nuclides with 

multiple modes of transformation, the branch formed by each mode must be followed. In some 

instances the branches may converge. It should be noted that the branching fractions may not 

always add to exactly one, since only branches leading to radioactive decay products are 

tabulated, and because of uncertainties in the fractions. The stated values are considered to be 

appropriate for use in dosimetric calculations. 

The serial transformation by radioactive decay of each member of a radioactive series 

is described by the Bateman equations (ICRP, 1959; Jacquez, 1972; Skrable et al., 1974). 

Assume that at time zero the concentration of the parent nuclide on the surface of the ground 

is A1 

o 

 (Bq m-2) and that the effective dose equivalent HE for an exposure period of one year is 

to be estimated. The contribution to effective dose from nuclear transformation of the parent 

nuclide would be given by 

A o 

h gs 1 HE E,1 1 e 1T  ,  (A.1) 1 

h gs

where E,1 denotes the effective dose equivalent coefficient from ground surface exposure for 

nuclide 1 (Sv per Bq s m-2), 1 is the decay constant, in inverse seconds, for nuclide 1 

(  0.6931/ T1/2 ), and T equals 3.15 x 107  s or one year. Using the Bateman equations, the 

activity at time t of chain members i, i = 1, 2, ..., can be expressed as 

i1 i  t 

A  , i (t ) A1

j, j1 j  i

where

ai  , i 1 1, if n  0

and f

j, j1 denotes the denotes the fraction of the nuclear transformations of chain member j 
196


forming member j+1. The effective dose equivalent associated with an exposure period of 

duration T, following a contamination event at t = 0 that results in a ground surface 

concentration of A1 

o 

 , is 

n i1 i

j	 (k j ) (A.3)

k j 

h gs

where E, i denotes the effective dose equivalent coefficient for ground surface exposure to 

nuclide i , and all other factors are as defined above. If the parent radionuclide is long-lived 

relative to the decay products, then at times T such that i T > 5, i 2 to n , HE  can be 

estimated as 

n i1 

HE A1 

o 1 e 

1 t 

h gs   E, i f

j, j1 .	 (A.4) 1 i1 j1 

Under these conditions the activity of the decay products is in secular equilibrium with the 

parent's activity. For example, application of Eq. (A.4) to 137Cs and its 137mBa decay product 

[ h gs A o   0.946 h gs 

E,Cs137 E,Ba137m ], Cs137 

HE Cs137 

1 e Cs137 t 

would yield where 0.946 is the fraction of the 137Cs nuclear transformations forming 137mBa. 

If the decay products are not short-lived relative to the parent, then it is necessary to evaluate 

Eq. (A.3). In many instances, the mathematical models describing the fate of radionuclides in 

the environment; e.g., their dispersion of following release to the atmosphere, includes an 

evaluation of the ingrowth of each radioactive decay product. The information in Table A.1 

should be useful to those implementing such models.

APPENDIX B 

MODIFICATIONS TO THE HUMAN PHANTOM 

Organ doses were computed for 25 organs in the Cristy adult hermaphrodite phantom 

(Cristy and Eckerman, 1987). Two modifications were made to the phantom before the 

calculations were performed. In the first, the head region was modified to include a neck 8.4 

cm high and 10.8 cm in diameter, and the right elliptical cylinder comprising the lower portion 

of the head was shortened from 16.85 cm to 13.05 cm. The y-coordinate1

 of the center of the 

concentric cylinders bounding the lobes of the thyroid was changed from -4.00 cm to -2.30 cm 

to place the thyroid in an appropriate position for external dosimetry studies. The upper portion 

of the spine was also relocated to a more appropriate position by changing the y-coordinate of 

the center of the bounding elliptical cylinder from 5.50 cm to 1.45 cm. 

The second modification was the addition of an esophagus model, which is divided into 

two parts. The thoracic portion lies within the upper trunk and contains a small amount of air 

(represented by a void in the model). It is described as the region between two right elliptical 

cylinders:

where a = 1.17 cm, b = 0.42 cm, d = 0.3 cm, y0 = 2.575 cm, z2 = 43.0 cm, and z3 = 70.0 cm. 

The abdominal portion lies within the upper abdomen (middle trunk of the phantom) and is 

closed. It is described by a right circular cylinder:

The origin of the coordinate system is at the center of the base of the trunk section of the 

phantom. The z-axis is directed upward toward the head, the x-axis is directed toward the left 

side of the phantom, and the y-axis is directed toward the posterior of the phantom.

APPENDIX C 

EXTERNAL BREMSSTRAHLUNG 

When electrons decelerate in a medium, a fraction of their kinetic energy is converted into 

energy in the form of photons. In this context, the photons are called bremsstrahlung from the 

German word for braking radiation. This type of radiation is further specified as external 

bremsstrahlung. Bremsstrahlung emitted when an electron is ejected from the nucleus in the beta 

decay process is called internal bremsstrahlung. Generation of bremsstrahlung is a stochasticallygoverned process and the bremsstrahlung can range in energy from zero up to the initial kinetic 

energy of the electron. Hence, for a large collection of monoenergetic electrons, a continuous 

bremsstrahlung energy spectrum is generated. 

Calculations of bremsstrahlung spectral shapes are quite tedious because of the complexity 

of the bremsstrahlung cross-section formulas. However, Pratt et al. (1977) tabulated bremsstrahlung 

cross-section data for electrons of kinetic energy between 1 keV and 2 MeV incident on neutral 

atoms of atomic number between 2 and 92. This tabulation is based on an extensive set of numerical 

calculations of the bremsstrahlung cross-sections carried out by Tseng and Pratt (1971) and by Lee 

et al. (1976). The cross-section values are believed to be accurate within at least 10%. 

Dillman and Eckerman (1993) have tabulated scaled bremsstrahlung spectral shape data from 

electrons of kinetic energy between 1 keV and 10 MeV incident on neutral atoms of atomic number 

between 1 and 92. Their tables provide values of bremsstrahlung spectra, multiplied by a scaling 

factor of 100 k / T , as a function of k / T where k is the bremsstrahlung energy and T is the kinetic 

energy of the electron. These tables are based on the cross-section values of Pratt et al. (1977) with 

an extension of their data to electron kinetics energies up to 10 MeV. 

Tables C.1 through C.3 provide scaled values of S ( k, T ), the bremsstrahlung spectra 

produced at photon energy k for initial electron kinetic energy T in units of keV for air, water, and 

soil, respectively. The tabulated quantity is S ( k, T ) in units of photons MeV-1, multiplied by a 

dimensionless scaling factor of 100 k / T . The scaled quantity, designated as S 

( k, T ), is tabulated 

for a grid of 27 electron kinetic energy values ranging from 1 keV to 10 MeV; for each electron 

energy, there are entries for 12 values of k/T ranging from 0.0 to 0.95. The tabulated quantity 

approaches zero as k/T approaches 1.0 so a table entry at k/T = 1.0 is not necessary. The fraction of 

the initial kinetic energy of an electron that is converted to bremsstrahlung, that is, the radiation yield 

215

216


Y, is given by 

T k Y  S ( k, T ) dk o T (C.1) 

1 T 

100 o

S   ( k, T ) dk .

S  The radiation yield Y ( k, T ) must, of course, be less than 1. The values of for the slowing-down 

medium are folded with the beta spectrum to obtain the bremsstrahlung spectrum associated with 

beta decay. Defining S ( k, To ) as the bremsstrahlung spectrum (photons MeV-1 per Bq s) at energy 

k for a beta spectrum with endpoint kinetic energy T0, we have 



o S ( k, T  o ) T Y ( T ) S ( k, T ) dT   k (C.2) 

T o Y ( T ) S 

( k, T )   k 100 k / T 

dT , 

where Y (T) is the probability per unit energy of beta emission with kinetic energy T. 

The beta spectrum Y may be calculated using the Fermi theory of beta decay. In this work 

we have used spectral data computed using the EDISTR code of Dillman (1980). Fig. C.1 shows 

the external bremsstrahlung spectrum of 85Kr in air computed using these data. External 

bremsstrahlung spectra were calculated in this work only for beta particles slowing down in air, 

water, and in soil. We applied the information of Dillman and Eckerman (1993) to positrons even 

though important differences exist in the slowing-down process between electrons and positrons. 

For positron emitters, the annihilation photons, not bremsstrahlung, are the major penetrating 

radiations. 

For exposure to contaminated soil, it has been assumed that all emitted beta particles slow 

down in the soil. This assumption overestimates the bremsstrahlung contribution for beta emitters 

on the soil surface.

Fig. C.1. External bremsstrahlung spectrum of 85Kr in air. 
APPENDIX D 

EXAMPLE CALCULATIONS 

This appendix provides a series of example calculations intended to illustrate certain aspects 

of the data presented in Tables III.1 to III.7 and in Table A.1. It is not the purpose of this appendix 

to suggest or endorse formulations regarding the behavior of radionuclides in the environment. 

Thus, the examples are of a pedagogical nature. 

Example 1. The concentration of 85Kr, , in the atmosphere at a location in the CKr85 

environs of a fuel reprocessing plant is estimated to be 1000 Bq m-3. Compute the annual effective 

dose and the dose to skin. Assume the exposure is continuous and without benefit of any shielding 

by structures. 

From Table III.1 the coefficients for air submersion for 85Kr are 1.19 × 10-16 for the effective 

dose and 1.32 × 10-14 Sv per Bq s m-3 for the skin dose. The annual effective dose, HE , can be 

estimated as the product of the dose rate and the exposure duration of 3.15 × 107

 s (1 year) as 

H t E  hE CKr 

1.19 × 1016 Sv m 3 

× 103 Bq × 3.15 × 107  s

Bq s 3 m 

3.75 × 106  Sv ( or 0.375 mrem ) .

The skin dose would be 

H  t skin hskin CKr 

1.32 × 1014 Sv m 3 × 103 Bq × 3.15 x 107  s

Bq s 3 m 

4.16 × 104  Sv ( or 41.6 mrem ) .

Example 2. Consider that at time zero the ground surface was uniformly contaminated with 

pure  137Cs at a level of 2 Bq m-2. Calculate the effective dose equivalent rate, HE , at time zero and 

at ten years. Also compute the annual effective dose in the year following the initial deposition. 

Assume that radioactive decay is the only mechanism by which the radioactivity is removed from 

the ground surface.

The radiological properties of the radionuclides are summarized in Table A.1 of Appendix 

A. From that table it is seen that 137Cs has a physical half-life of 30 years, undergoes beta decay, and 

emits, as electrons, a total energy of 0.187 MeV per nuclear transformation (nt). No alpha or photon 

radiations are emitted. In 94.6% of the 137Cs transformations the radioactive decay product, 137mBa, 

is formed. Table A.1 indicates that 137mBa has a half-life of 2.552 minutes, forms no radioactive 

decay products, and emits electrons and photons with total energies of 0.065 and 0.597 MeV nt-1, 

respectively. The energies listed in Table A.1, and quoted above, are the energy of all radiations of 

that type emitted per nuclear transformation. A nuclide emitting a single photon of energy 1 MeV 

in 1% of its transformations releases the same energy in photon radiation as another nuclide emitting 

photons of 0.01 MeV in 100% of its transformations. The dosimetric significance of these photons, 

however, can be quite different. Barium-137m emits a gamma ray of 0.6616 MeV in 89.8% of its 

nuclear transformations; the total energy emitted is 0.6616 × 0.898 or 0.594 MeV nt-1. The tabulated 

value of 0.597 MeV includes the contribution from K x rays emitted following the internal 

conversion of the 0.6616 photon. Note that the sum of the emitted energies (0.065 + 0.597) is about 

0.6616 MeV  the energy of the metastable state. 

At time t = 0, the ground surface is uniformly contaminated with pure 137Cs; the decay 

product, 137mBa is not present. From Table III.3, the effective dose coefficient, , for 137 h Cs Cs137 

distributed on the ground surface is 2.85 × 10-19 Sv s-1 per Bq m-2. Note that the dose coefficient is 

stated here as an instantaneous dose rate per activity concentration. The dose rate at time zero is 

Bq H

E 2.85 × 1019 Sv m 2 

 × 2.0 

Bq s 2 m 

5.70 × 1019 Sv  . s 

This dose is due to bremsstrahlung arising as the beta particles emitted by 137Cs slow down in the 

ground. Recall that Table A.1 did not indicate the emission of photons by 137Cs. 

To compute the effective dose rate after ten years, we first compute the activities of 137Cs 

and 137mBa on the ground surface at that time. Equation (A.2) of Appendix A provides the necessary 

formulation which yields

Cs137  Ba137m is the fraction of the 137Cs transformations forming 137mBa and ACs137(0) is

on the ground surface at ten years (3.15 × 108

The 137mBa is in secular equilibrium with its parent 137Cs. A decay product is said to be in secular 

equilibrium when the ratio of its activity to that of the parent no longer changes with time; in the 

case of 137mBa this ratio is simply the fraction of 137Cs transformations forming 137mBa (0.946). Using 

the dose coefficient from Table III.3, we obtain

Activity, by definition, is the rate at which nuclear transformations are occurring and thus, its time 

integral is the number of nuclear transformations during the time period. Equation (A.3) provides 

the necessary formulations to compute the number of nuclear transformations. The number of

Example 3. Consider that the 137Cs contamination of Example 2 was uniformly distributed 

within the top 5 cm of the soil at ten years. What is the effective dose rate for the volume-distributed 

137Cs and 137mBa activities? 

The activities at ten years calculated above are valid. However, the activity is now 

considered to be distributed in the top 5 cm of the ground. The volume activity of 137 Cs is 

A V (t)

Cs137  5 cm × 102 m/cm

and the volume activity of 137mBa is 30.0 Bq m-3. From Table III.5, the effective dose coefficients 

for 137Cs and 137m Ba uniformly distributed in the top 5 cm of the ground are 3.07 × 10-21 and 1.09 

× 10-17 Sv per Bq s m-3, respectively. Thus, the effective dose rate is 

Bq	 Bq H

  × 30.0 

Bq s 3 m 3	 Bq s m 

3.27 × 1016 Sv  . s 

Note that the dose rate from the volume-distributed activities is about a factor of three lower than 

the corresponding value had the activity remained on the ground surface. 

Example 4. Soil concentrations of naturally occurring 40K are typically about 370 Bq kg-1 

with a range of 100 to 700 Bq kg-1. Assuming that the potassium is uniformly distributed in the soil 

to an infinite depth and the density for the soil of interest is 1.9 × 103

 kg m-3, calculate the effective 

dose rate. 
226


Tables III.4 - III.7 provide dose coefficients for radionuclides uniformly distributed to 

various depths in a soil having a density of 1.6 × 103

 kg m-3. Table III.7 gives dose coefficients for 

radionuclides distributed to an infinite depth. A radionuclide is said to be distributed to an infinite 

depth when a further increase in the thickness of the contaminated region does not result in an 

increase in the dose rate at the surface. For an infinitely thick source (Table III.7) the effective dose 

coefficient for 40K is 5.57 × 10-18. The introduction to Table III.7 notes that one can scale the dose 

coefficients in this table for a soil having density different from the value used in deriving the 

coefficients. Scaling is accomplished by multiplying the tabulated values by the ratio 1.6 × 103

/, 

where is the soil density in kg m-3. Therefore, the effective dose coefficient for the soil of interest 

is 

5.57 × 1018 Sv m 3 

× 

1.6 × 103 

4.69 × 1018 Sv m 3

. Bq s 1.9 × 103 Bq s 

The 40K activity of 370 Bq kg-1 in a soil having a density 1.9 × 103

 kg m-3 corresponds to a 

volumetric source strength of 7.0 × 105

 Bq m-3. Thus, the effective dose rate for this soil density and 

40K concentration is
