Shielding Against Gamma Rays, Neutrons, and Electrons From

Nuclear Weapons. A Review and Bibliography

J. H. Hubbell and L. V. Spencer

The problem of predicting dose rates and of estimating the effectiveness of shielding

from radiations resulting from nuclear explosions is discussed. A number of existing calculations and supporting experiments regarding the penetration and diffusion of gamma rays, neutrons, and electrons through air and bulk materials are summarized. Indications are given of gaps in such input information. A selection of 485 references from the unclassified

literature is presented, of which 388 are cataloged as to source geometry and energy, absorber

material and configuration, type of data presented, and method of calculation or experimental technique. These cataloged references include radiation field studies ranging from

the point-source infinite-medium situation up through such complicated geometries as foxholes, shelters, and conventional structures. The other references are of a general or review nature or contain input spectral data.

I. Preliminary Statement

The problem of shielding against radiation due

to nuclear weapons involves estimation of the

radiation dose in an arbitrary configuration of

radiation sources and shielding materials. In making such estimates, data for simple structure

types have been very useful. This is because a

complicated structure can often be schematized

as a combination of simple structures. From our

point of view, the infinite, homogeneous medium,

i.e., the total lack of structure, may be considered

the simplest case, as well as the most useful. In NBS Monograph 42 [Gl],* gamma-ray data

generated for infinite, homogeneous media are pre- sented in engineering-type graphs; and the use of

these data in analyzing many elementary structure types is discussed. A more complete engineering

methodology, for analyzing complicated as well

as simple structures, is given in a parallel series

of OCD reports [G46, G47].

This Monograph is primarily a catalog and

bibliography of experiments and calculations

relating to simple configurations, including the

infinite, homogeneous medium. It extends the

documentation of [Gl] and indicates the availability of data, calculations, and corroborative

experiments for neutrons as well as gamma rays. The next few sections of this introduction are designed to introduce the configurations considered "elementary," the types of data which

have been the object of research efforts, and some

types of data which have been omitted or only

partially included here. The gamma-ray re- ports constitute the largest single group listed,

with neutron reports second. For completeness, reports on electron penetration have also been included.

We have tried to include all unclassified re- ports and publications which have seemed di- rectly pertinent to the basic problems of weapons

shielding, and which involve elementary configurations. At the same time, we are quite

certain that we have missed reports, some very

important; and we would greatly appreciate

having our attention called to such oversights.

II. Comparison of Different Approaches

The use of data for elementary configurations

is only one approach to the study of radiation

shielding problems. A second approach utilizes mockups of interesting configurations in the

vicinity of test explosions. This "field test" type of experiment provides a direct answer to

a specific shielding question even in very complicated cases. By performing a large variety of

field test experiments it is possible to arrive at a

"feeling" for the propagation of radiation from

nuclear devices. But the number of variables even in relatively simple cases is very large;

and the approach is therefore not naturally extensible to new situations.

A complementary procedure is that of attempting to study small-scale mockups exposed to radiation resembling that from weapons. Experiments of this type may be performed in a laboratory relatively cheaply and easily. Beyond

1
these advantages, such model studies can give

information on effects due to changes in a structure or radiation source. With models, it is much

more nearly possible to arrive at an understanding

of radiation effects through a single type of

experimentation. It is unfortunate that the

model approach has seemed to be unsuited to the

study of shielding against neutrons.

All of these methods reinforce and complement

one another in different ways, since each is appropriate to specific types of shielding questions.

But, it has been advantageous to turn even field tests and model studies to the investigation of

particularly important examples of elementary

configurations; and a number of research papers

describing such work are given.

III. Types of Information

Figure 1 gives a block diagram of the types of

information required for the interpretation of

radiation effects from nuclear weapons. In brief,

the top row of blocks identifies the radiations

generated in the elementary nuclear reactions.

In the second row of blocks, these different types

of radiation are divided into two groups, initial and delayed radiations. It should be noted at

this point that the spectra which correspond to the elementary reactions (top row) will be modified

by weapon design and its location at detonation.

Thus, the spectra of "initial" and "delayed"

radiations will not be a simple superposition of

spectra for the elementary reactions.

Both initial and delayed radiations penetrate

is affected by the geometry of the source and by

the configuration of the absorbers. The third

and fourth rows on the diagram of figure 1 stand

for information of this type.

Lastly, the detector determines the radiation!

characteristics which are measured. The detector

response can be viewed as a parameter charac-i; terizing the spectrum. It is usually convenient

to agree on standard types of detector response'

and in this way subordinate the discussion of the

radiation spectrum to other features of the

problem.

Source spectra, penetration, and geometry

information are all necessary for a reasonably

complete understanding of radiation effects and

an ability to make predictions for new configurations. Much spectral information, particularly

that indicated by the second row in the diagram,

is classified because one can deduce from it certain

things about the design of a weapon. This doesJ

not decrease its basic importance in shielding

problems, and one way or another it must be

taken into account. Here we omit all such information. The gaps which result have the nature

of missing multiplicative constants and do not

necessarily result in a misleading picture of the cur- rent status. Further, it is possible to perform

calculations or experiments for individual components which may appear in the spectra, and to make a superposition at a later time when data on

source strengths are available.

IV. Basic Spectral Components

While we do not attempt to catalog the large

body of reports dealing with the spectra of specific source components, a few comments about the

state of information on the main components

follow.

A. Initial Radiations

Proceeding from left to right along the top row of figure 1, we consider first the initial radiations. Neutrons are produced in great abundance,

two or more from a fissioning nucleus. Neutrons

also result from fusion reactions. The spec- trum from fast neutron fission has been determined, and is given by the solid curve in figure

2 [SD22]. The spectrum from individual fusion

reactions is known although one does not know

relative strengths. The dashed lines in figure 2

represent several fusion neutron spectral energies

[G20]. In general, fusion neutrons are higher in energy and correspondingly tend to be more penetrating than fission neutrons. The prompt fission gamma spectrum is reason- ably well known. The curve in figure 3 is from

an experiment by Francis and Gamble [SDlO] in which gamma photons were detected in coin-j

cidence with fission fragments in a fission chamber.

The penetration of initial gamma rays is likely to be influenced by neutron capture in nitrogen

of the air, since this reaction produces very high

energy gamma rays [SD12], as indicated by the

'SD

2
dashed lines in figure 3. These capture gamma

rays are not only more penetrating than the

fission gamma rays, but they also start from

locations determined by the penetration of neutrons. Thus, they "ride piggy-back on the neutrons" for part of their way. Other (n, y)

reactions must contribute to the initial radiation,

but those of figure 3 may well be the most important because of their penetrability and also because of a substantial cross section for the

capture process.

1

B. Delayed Radiations

Next we turn to the delayed radiations. The

fallout spectrum is produced by superposition of

spectra from reactions having many differing halflives. Correspondingly, the spectrum may change

drastically as a function of time after the detonation, and it is necessary to determine spectra either

for time intervals or for particular times of interest.

Since the spectrum from a pile corresponds to a very long time interval, whereas the times and

time intervals for shielding against fallout radiation are relatively short, pile research makes only

a limited contribution to our information about

this component.

There has been an increasing body of data on

delayed gamma rays from fission. Most of this information comes from calculations of the yield

of different nuclear species as a function time after

> fission. In figure 4, spectra obtained by Bjornerstedt [SD2] in this way is given. Experimental

information is available on spectra corresponding

both to short and long times after fission, and an

example of this type of data is given in figure 5 [SD25].

Figure 5. Fission-product gamma-ray spectra measured at short times after U—235 sample irradiation, using Compton and pair spectrometers [SD 25]. It should be remembered that spectra from two

different fissioning atoms will differ from one

another, and also that spectra from slow-neutron

fission will differ from spectra corresponding to fast-neutron fission. But to date, the evidence

suggests that penetration differences which result

from differing spectra are minor [Gl].

Several types of (n, y) reactions have importance

for delayed (fallout) spectra. Figure 6 gives some

of the gamma-ray energies which result from

neutron capture in uranium or neptunium. Note

that they are mostly rather low in energy. Mather

[SD15] has published sample pulse-height distri- butions for fallout which clearly show the 2.8 Mev component of Na24 produced by neutron

capture in the ground, the 1.6 Mev gamma rays

from La140

, and the longer-lived 0.75 Mev activities of the Zr95-Nb95 decay chain. The possibility of introducing other contaminant materials

into the detonation has been given some publicity.

but there is very little unclassified information

available on the subject.

Next, we consider the delayed beta rays from

fission. While these particles are not very penetrating (see fig. 9), they have produced serious

burns in the case of the Marshallese Islanders ; and

they represent a hazard also through ingestion

into the body with food, water, or air. Figure 7 gives some of the (rare) data on the gross fission beta spectrum. It was measured by the Japanese

several weeks after contamination of the Lucky

Dragon.2

C. Effects Which Modify Initial and Delayed

Intensities and Spectra

It is possible to describe qualitatively some of

the spectral characteristics which are determined

by the detonation geometry; but quantitative

information is, of course, classified. For example, a bomb cannot fly apart with

anything like the speed of light because of equipartition of energy and the considerable atomic mass of the constituent elements.3 But the prompt

gammas and high energy prompt neutrons travel

essentially with the speed of light. They must

therefore penetrate the outer layer of bomb material and subsequently the air prior to other dis- turbances. The intensity of the prompt radiation

emerging into the air will therefore be lowered

and the spectrum of both gammas and neutrons

will be altered. Fortunately, however, neutron

and gamma-ray spectra are often rather insensitive to penetration. Because of this, the continuous nature of the spectra, and the greater

penetrability of high energy components, such

spectral modifications are not likely to dominate

the penetration through air and shield. The main

effect of the weapon geometry is thus the introduction of unknown multiplicative constants. Subsequent phenomena include the removal of

the air from an enormous volume about the initial detonation, with corresponding high compression

of the air at the air-vacuum interface. This modification of absorber geometry does not change

spectra or angular distributions very much; but

it may affect the air attenuation considerably

while this "shell" configuration persists. Note

that prior to the passage of the compression wave

the number of mean free paths of air protecting a detector location decreases due to concentration

in the shell, while after passage of the compression wave there may be a decrease due to removal

of air to positions beyond the detector.

The fallout spectra produced by fission products

should be similar to the theoretical gamma-ray

and beta-ray spectra from fission. But one hardly

expects to see contributions from volatile materials, such as the rare gases, which may occur among the fission products. These materials

should remain in the atmosphere. Other modifications may result from differences with time in

the chemical and physical behavior of fission product elements; and the magnitude and nature

of these modifications are extraordinarily difficult to estimate. The generic term "fractionation" is used for these effects. Finally, we might simply note that the source

strengths of both prompt and delayed (n, y) radiations from air, earth, or bomb constituent

materials are a function of the type of detonation

and its location.

697-763—64 2 5
V. Radiation Penetration in the Absence of Boundaries

Particular interest attaches to the study of

penetration in the absence of boundaries, as already mentioned, this being the case most

amenable to detailed theoretical study. For a given source strength S(r,E) of gamma rays, neutrons, or beta rays, emitting energy E at location r, in a medium without boundaries, a variety

of data types can be determined, some of which

are indicated in figure 8. Proceeding from left to

right, we may wish to know simply an integral

which can be generically termed the "dose." We

may wish to know how different spectral components contribute to the "dose." Or, we may

wish to know from which directions the "dose"

is delivered. (Directional information may be

put in integral form, and may be referred to as "geometry factor" data. Similarly, "barrier

factor" data refer to "dose.")

The last item in figure 8 refers to the amount

and kind of radiation reflected from a surface, and

this implies a boundary.

Extensive investigations of these quantities

have been made. Tables 1 to 4 outline much of

the available literature for gamma rays and neutrons. Note that although our comments pertain

mostly to point isotropic (PTI) sources, other

source configurations are also important. For

example, data on plane isotropic (PLI), plane

slant (PLS), and other source geometries have

proved useful and have been determined experimentally or theoretically.

In general, the study of neutron penetration is more difficult than the study of gamma-ray penetration because the cross sections are less well

known and more irregular, and because detection

presents more of a problem. The number of ele- ments whose cross sections are known completely

enough to permit a fairly reliable theoretical

analysis is still small. Further, measurement of

neutron intensities is far easier than measurement

of spectra or directional distributions. These

things contribute to the generally less satisfactory status of neutron penetration data.

The study of beta-ray penetration from fission products is still in its infancy, partly because the

shielding problem appears to be easily soluble. Nevertheless, information of this type has its applications. Figure 9 gives results from the one

theoretical fallout beta study available at the

moment [ET5]. Tables 5 and 6 summarize the

literature.

VI. Elementary Configurations With Boundaries

Most of the studies in tables 1 to 4 are either

theoretical analyses or descriptions of laboratory

experiments, but the field tests have made contributions also. In figure 1 1 are data on the penetration of fallout gamma rays into concrete, as determined by measurements on one of the test shots

in Nevada [GE54]. The experiment is diagramed

in figure 10. Unfortunately, lack of unclassified

information about the device limits our possibility

of analyzing this data theoretically.

Intensities at T <1 hr exceeded the ranges of the detectors, and should be

is still contained in the Effects of Nuclear Weapons

[G20]. This summary, unfortunately, is not documented with references to specific sources of data,

but references to several other summaries are included in the 1962 revision, as well as lists of

publications by the OCDM and by the USAEC,

Civil Effects Test Operations.

In figure 12 a number of elementary absorber

configurations are sketched. Note that more

complicated structures contain different combinations of those pictured. For example, an underground shelter can be considered as a combination

of shielded foxhole with a maze entrance and possibly a maze ventilation system. Correspondingly, an above-ground shelter might be a blockhouse.*

This combines a vertical v;all, possibly vents in the

walls, and an overhead slab which shields in the same manner as in the case of the shielded base- ment or foxhole. The foxhole (unshielded) is self- explanatory. Most frame houses are simple light

superstructures. A large apartment building would

perhaps combine a blockhouse, with vertical walls,

compartmentation, vents, and in-and-down configurations. To complete our fist in figure 12,

we might note that the air-ground density inter- face plays an important role in structure shielding.

Tables 7 to 9 give studies of these elementary

geometries. The special topic of mazes, or ducts,

has been treated separately because of the attention which it has received.

Note that neutron penetration data for ele- mentary configurations are still scarce, that many

of the papers on these topics are recent, and

that some configurations have as yet received little attention. These configurations may not be as

well chosen for neutrons as for gamma rays.

* The term "blockhouse" is used generically, as are all these designations. We do not imply a limitation to a particular shape.

VII. Experiments and Calculations for Structures

A table of experiments and calculations for existing buildings and other structures has been

included (table 10). Here the elementary configuration data are applied and tested. There exist

measurements and calculations for light structures,

below-ground shelters, and large, fairly regular

structures. It should be noted that the analysis

of the experimental data on mazes is most extensive.

Another reservoir of structure data is the Federal

Shelter Survey [G47]. Presumably, analyses of

these data will be made in the future. Results

of the Survey calculations can be obtained; but

these calculations were not very sophisticated.

VIII. Final Comments

1 . -J

We might note that more than one source configuration of potential importance had been very

little explored. For example, only a few papers

exist which deal with the enveloping cloud of

fallout; and hardly any work has been done for a uniform distribution of fallout over all exposed

surfaces. Both cases, and others which might be

relevant at different times in different weather

conditions, are illustrated in the sketches of figure 13. The most concentrated effort of the near future

is likely to be in the area of neutron penetration.

Both calculations and experiments for a number of

elementary configurations are in progress. There is apt to be more on electron penetration

in the future, not because of shielding against

nuclear explosions, but because of space vehicle

shielding problems which have recently come to attention.
