4.0

The occupational environmental dose is the dose received by workers on the job, but outside the 

operational buildings at the Dayton Facilities and Mound Laboratory. This analysis estimated annual 

intakes from the inhalation and ingestion of radioactive materials at the Dayton Facilities from the 

available outdoor radionuclide air-concentration data. Ambient external dose at the Dayton facilities 

was estimated using available control badge data and a review of available radiation protection 

practices at the Dayton Facilities. 

OCCUPATIONAL ENVIRONMENTAL DOSE

Annual inhalation intakes of radioactive material at Mound Laboratory have been estimated based on 

the onsite environmental air monitoring station results from 1971 through 2003. For years in which 

onsite air monitoring data were unavailable (prior to 1971) and total Mound stack effluent data was 

available, empirically derived onsite atmospheric dispersion factors (plutonium, polonium particulates, 

and hydrogen gas/vapor χ/Qs) were used to estimate the intake air concentration. The χ/Q derivation 

coupled the site-wide median air concentration (238Pu, 210Po, and 3

H concentration) with the 

corresponding total Mound effluent source term for the period from 1973 through 1983. Ingestion 

intakes and ambient external dose were estimated using radionuclide concentrations measured in 30-

cm-thick soil samples at Mound Laboratory. 

Sections 4.1 and 4.2 discuss reconstruction of dose for unmonitored environmental exposures at the 

Dayton Facilities and Mound Laboratory, respectively. Section 4.3 discusses uncertainties for this 

analysis.

Technical Basis Documents (TBDs) and Site Profile Documents are general working documents that 

provide guidance concerning the preparation of dose reconstructions at particular sites or categories 

of sites. They will be revised in the event additional relevant information is obtained about the 

affected site(s). These documents may be used to assist the National Institute for Occupational 

Safety and Health (NIOSH) in the completion of the individual work required for each dose 

reconstruction.

In this document the word “facility” is used as a general term for an area, building, or group of 

buildings that served a specific purpose at a site. It does not necessarily connote an “atomic weapons 

employer facility” or a “Department of Energy facility” as defined in the Energy Employees 

Occupational Illness Compensation Program Act of 2000 [EEOICPA; 42 U.S.C. § 7384l (5) and (12)].

4.1 DAYTON FACILITIES

The principal contaminant at the Dayton Units was 210Po. Dayton Unit I was occupied in September 

1943 and was located at 1515 Nicholas Road, Dayton, Ohio. Available reports indicate that 210Po was 

not produced at Unit I and that operations were transferred from Unit I to Unit III in October 1943. 

However, various research projects that did involved radionuclides were conducted at Unit I after 

1943, some of which were transferred from Mound. These projects involved relatively small quantities 

of 14C, 3

H, and 210Po (DOE 1993b, Mound Site profile). 

The 210Po production process was set up initially at Dayton Units III and IV and later at Unit V. Dayton 

Units III and IV were occupied in October 1943 and February 1944 respectively to extract 210Po from 

radioactive feedstock supplied by the Hanford Works in the State of Washington (DOE 1993b). From 

November 1944 to January 1945, a small amount of 210Po was obtained from radioactive lead ores. 

At the same time, large amounts of 210Po were obtained from irradiated bismuth (Wolf 1945). Unit III 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 9 of 113

was located at Bonebrake Theological Seminary, 1601 First Street, Dayton, Ohio. Unit IV was located 

at Runnymeade Playhouse at Dixon Avenue and Runnymeade Road in Oakwood, Ohio. Dayton Unit 

II was a separate district Monsanto facility located in Dayton that was not involved in AEC activities. 

In 1949, operations involving fabrication of atomic bomb initiators using 210Po transferred from Dayton 

Units III and IV to Mound Laboratory (Unit V). 

4.1.1 Dayton Units Environmental Monitoring 

Available Dayton Unit III and IV data consist of Progress Reports for July, August, September, 

October, and December 1945 (Monsanto1945a through 1945i); Monthly Health Reports for November 

and December 1947; and Monthly Health Reports for January and March 1948. No data was 

available for 1943, 1944 and 1946. Available data indicate that gross alpha air sampling was being 

conducted in both the indoor and outdoor areas of Dayton Units III and IV by 1947. All gross alpha air 

sample results were assumed to be due to 210Po. A review of the available air sample results for 

Dayton Units III and IV in 1945, 1947 and 1948 indicates that 210Po airborne concentrations in the 

operational areas of Units III and IV unit were very similar. Clean area and hallway air sampling 

results at both units III and IV in 1945 were typically between 0.1 and 0.5 times the acceptable 

“tolerance” (permissible) level of 2,400 dpm/m3 or between 1.08E-10 to 5.40E-10 uCi/ml. 

In addition, the outdoor site perimeter air monitoring results from Units III and IV in November and 

December 1947, January 1948 and March 1948 are comparable. Gross alpha levels outside Unit III 

in March 1948 averaged 1.08E-11 while the levels outside Unit IV averaged 1.62E-10 (Miller and 

Haring, 1948). Tables 4-1 through 4-6 below present the results of weekly perimeter fence air 

sampling at units III and IV in November 1947, December 1947 and January 1948. Dayton Unit III 

weekly outdoor perimeter air sample data for the month of December in 1947 are the highest outdoor 

air monitoring data available for the Dayton Units. Due to the lack of available environmental air 

monitoring data for the Dayton Units, the environmental intakes for both Dayton Units III and IV has 

been determined using the December 1947, Dayton Unit III, data. The median 210Po outdoor 

perimeter airborne concentration for Unit III (4.86E-10 uCi/ml) is shown in Table 4-3 below and is 

assumed to be applicable to Dayton Units III and IV from November 1944 through 1948 (See Table 4-

7). The air sampling data is also assumed to incorporate the resuspension component due to any soil 

contamination that may have been present.

4.1.2 Intakes From Inhalation of Airborne 210Po 

Environmental intakes are assumed to have occurred beginning in November 1944 when actual 210Po 

production started at Units III and IV as reported by Wolf (Wolf 1945). 

Annual 210Po inhalation intakes are the product of the median 210Po environmental air concentration 

and 2,400 m3

/yr, which is the product of the breathing rate (1.2 m3/hr) of reference man doing light 

work and an exposure duration of 2,000 hr/yr. Table 4-8 below presents the annual environmental 

intakes at the Dayton Units. Unit I environmental polonium intakes are assumed to be a factor of 

1,000 times less than the Unit III and IV intakes, because there was no polonium production at Dayton 

Unit I, and the work conducted at Unit I involved relatively small quantities of 14C, 3

H, and 210Po in 

dispersible form (DOE 1993b and Mound Site Profile). Polonium is assumed to account for 95% of 

the internal dose. The most claimant favorable absorption type should be chosen for dose 

reconstruction because of the various chemical forms of polonium that may have been used at the 

Dayton facilities.

a. Based on 8 weeks of 210Po production in 1944

An estimate of the uncertainty associated with the median environmental intakes presented in Table 

4-8 has been made by assuming that the intakes are lognormally distributed and that the median 

intakes in Table 4-8 represent the 50th percentile intake rate. The intake from exposure to the 

“tolerance” level of 2,400 dpm/m3 (96,000 Bq in each year from 1945 to 1948) for units III and IV and 

0.1% of the “tolerance” level for unit I are assumed to represent the upper 95th percentile intake. The 

resulting geometric standard deviation (GSD) is 1.6. 

4.1.3 210Po Intakes from Soil Ingestion

No soil sampling data are available from the 1940s for the Dayton Facilities to assess soil 

contamination levels. Due to the short half-life of 210Po, sampling conducted in the late 1990s is of no 

value. Assuming that soil resuspension accounted for 0.01% of the mean airborne 210Po measured in 

December 1947 at Dayton Unit III (See Section 4.1.1), the analysis estimated the 210Po soil

concentrations using the four-factor formula (equation 3-3) from the Savannah River Site TBD, as 

follows: 

CA = SD × CS × SF × RF

where:

CA = pCi/m3 Air

CS = pCi/kg Soil average 

SD = 1,600 kg/m3 soil

SF = 0.08-m surface factor

RF = 1 × 10-9/m resuspension

CS = CA/(SD × SF × RF)

Unit conversion and soil concentration calculations for Units III and IV: 

CA = 5.27 × 10-10 μCi/ml × 0.0001 × ml/cm3 × (100cm)3

/m3 × 1 × 106 pCi/μCi = 5.27E-02 pCi/m3

CS = 5.27E-02 pCi/m3

/(1,600 kg/m3 × 0.08m × 1 × 10-9/m) = 4.12 × 102 pCi/g (15.23 Bq/g)

Assuming 5 grams of 210Po contaminated soil are ingested per year results in an annual 210Po 

ingestion intake of 76.20 Bq. For the eight weeks of operation in 1944 the resulting intake would be 

12.20 Bq. The most claimant favorable absorption type should be chosen for dose reconstruction 

because of the various chemical forms of polonium that may have been used at the Dayton facilities. 

4.1.4 Dayton Facilities External Exposures

4.1.4.1 Annual 210Po Submersion External Exposures

This analysis calculated annual air submersion external exposures at the Dayton Facilities by 

multiplying the median airborne 210Po intake concentrations (Table 4-7) by 2,000 hours per year 

(occupancy) yielding an external submersion exposure of 1.30E+08 Bq s m-3 at Units III and IV. To 

assess the magnitude of submersion dose, the submersion exposure was multiplied by the effective 

dose coefficient of 4.16E-19 Sv per Bq s m-3 (Eckerman and Ryman 1993 reproduced in Tables 4A-1 

and 4A-2) for 210Po air submersion resulting in an air submersion effective dose of 5.4E-11 Sv. The 

resulting dose is well below 1 mrem; consequently, dose reconstructors need not consider 

submersion dose from effluents at the Dayton Facilities. 

4.1.4.2 Ground Layer External Exposures Attributed to Soil Contamination 

No soil sampling data are available from the 1940s for the Dayton Facilities to estimate environmental 

contamination levels. Due to the short half-life of 210Po, sampling conducted in the late 1990s is of no 

value. A radiological survey performed in May 1949 prior to the dismantlement of Unit IV indicated 

that contamination had been spread over the entire Unit IV area, which in some instances, exceeded 

2.0E+05 dpm per 100 cm2 total alpha contamination (Monsanto, 1950). Even though the 

contamination levels at the Dayton Facilities likely resulted from the gradual buildup of contamination 

over time, the reported level has been decay corrected back to the 1946 level of 7.80E+06 dpm per 

100 cm2 (1.30E+07 Bq per m2

). This analysis estimated external exposure attributable to 210Po soil

contamination at Units III and IV by assuming that the grounds surrounding Units III and IV were 

contaminated at a level of 7.80E+06 dpm per 100 cm2

. Based on an exposure duration of 2,000 hr/yr 

and an effective dose coefficient of 8.29E-21 Sv per Bq s m-2, (Eckerman and Ryman 1993), the 

resulting external exposure is 9.41E+13 Bq s m-2 yielding an effective dose of 7.80E-07 Sv. Based on 

the magnitude of the resulting dose (<1 mrem), dose reconstructors need not consider the external 

dose from the soil layer at the Dayton Facilities. 

4.1.4.3 Direct External Exposure From Facilities

No documentation of direct gamma radiation outside of the Dayton Facilities is available. The only 

documentation of a control badge result is for the week of May 17 to May 23, 1944, when a control 

badge result of 0.13 Roentgen or (0.9 mR/h) was reported (Tybout 1944). Assuming that the control 

badge data is representative of ambient dose rate outside the Dayton Facilities, the resulting dose for 

2,000 hours of occupational exposure is 1,800 mrem.

Direct external ambient dose could have resulted from gamma radiation originating within the 

operational buildings of Dayton Units III and IV or from the storage of waste material and or irradiated 

bismuth bricks within facility buildings or onsite structures. It is unlikely that gamma radiation 

originating from within the operational buildings of the Dayton facilities contributed to the ambient 

environmental dose. The irradiated bismuth bricks used at the Dayton Facilities were not canned in 

aluminum like the canned bismuth slugs that were irradiated at the Hanford facility and subsequently 

shipped to Mound. Consequently, the 60Co content of the slugs used at Dayton were much lower than 

the canned slugs used at Mound. According to a shielding study report from 1948, the work with 

polonium entails very limited use of shielding and whenever necessary, “operations are easily 

performed by valve handles extending through a lead or concrete shield” (Bradley and Haring 1948e). 

No detailed description of the administrative radiological control program pertaining to environmental 

exposure is available for the Dayton Facilities; however, there are several radiological control 

practices described in 1945 Progress Reports. On October 8, 1945, a shipment of 80 bismuth slugs 

was received at Unit IV, so a “lead pig barricade” was constructed in the southwest Greenhouse to 

store the slugs. In addition, a “keep out” sign and a barrier were posted four feet from the barricade in 

the Greenhouse where exposure rates measured <1 mR/h (Monsanto 1945g). 

According to an August 1945 Progress Report, two shipments of waste were shipped from Unit IV in 

August 1945. One of the shipments contained 15 barrels of waste in a Chevrolet truck with an 

exposur2e rate of 3.8 mR/h in the truck cab. The other shipment consisted of 18 barrels of waste in a 

“V-8 truck” truck with an exposure rate of 2.7 mR/h in the truck cab (Monsanto 1945c). 

Based on the anecdotal evidence presented in the progress reports and control badge results 

discussed above, an ambient, external dose rate of 0.90 mR/h or 1.80 cSv based on 2000 hours of 

occupational exposure per year appears to be a reasonable, claimant favorable estimation (Table 4-

9). Unit I ambient external exposures are assumed to be negligible based on fact that there was no 

polonium production at Dayton Unit I and that projects conducted there involved relatively small 

quantities of 14C, 3

H, and 210Po in dispersible form (DOE 1993b and Mound Site Profile).

For 1945 through 1948 an estimate of the uncertainty associated with the ambient dose has been 

made by assuming that the ambient dose is lognormally distributed and that the median annual dose 

of 1.80 cSv represents the 50th percentile dose. Exposure to the “tolerance” or permissible level of 15 

cSv per year is assumed to represent the upper 95th percentile dose. The resulting geometric 

standard deviation (GSD) is 3.6. For 1944 an estimate of the uncertainty associated with the ambient 

dose has been made by assuming that the ambient dose is lognormally distributed and that the 

median annual dose of 0.29 cSv represents the 50th percentile dose. Exposure to the “tolerance” or 

permissible level 0.5 cSv (500 mrem) per 40-hour week for 8 weeks (4.0 cSv) is assumed to represent 

the upper 95th percentile dose. The resulting geometric standard deviation (GSD) is 3.5 for 1944. 

 

4.2 MOUND LABORATORY

Mound Laboratory was an integrated research, development, and production facility performing work 

in support of U.S. Department of Energy (DOE) weapon and nonweapon programs with emphasis on 

chemical explosives and nuclear technology. Mound Laboratory originated as a technical 

organization in 1943 when the Federal Government requested Monsanto Chemical Company to 

accept responsibility for determining the chemical and metallurgical properties of polonium as a 

project of the Manhattan Engineering District (MED). Work occurred at Monsanto’s Central Research 

Department and several satellite units in the Dayton, Ohio, area. Late in 1945, the MED determined 

that the research, development, and production organization at Dayton should become a permanent 

facility. A search for a suitable location in early 1946 led to the selection of a 728,000-m2 (182-acre) 

tract adjacent to Miamisburg, Ohio, about 16 km (10 miles) south-southwest of Dayton. The facility is 

surrounded by residential and recreational properties as well as agricultural areas and sits atop an 

elevated area overlooking Miamisburg, the Great Miami River, and the river plain area to the west. In 

1981, DOE purchased an additional 123 acres of land south of the original 182 acres for unrealized 

mission expansion. This parcel was never developed.

Construction of Mound Laboratory began in February 1947 and ended in 1949. In late 1948, work at 

the Dayton Units moved to the Mound site. The following paragraphs describe key Mound facilities 

and their historic functions (DOE 1999; Monsanto 1975a, DOE 1993b). 

Semi-Works (SW/R) Tritium Complex 

This two-story facility was used primarily for handling tritium. Four major operations occurred in the 

SW/R Tritium Complex: component development, component evaluation operations, tritium recovery, 

and materials analysis. SW/R, which was built in 1950, underwent 13 major additions. One corridor 

of rooms in the adjacent building, Research (R), was converted to tritium operations; this corridor, 

together with the SW building and Building 58, formed the SW/R complex. While the complex was 

primarily a tritium facility, there were three additional areas. From 1951 through 1953 Mound 

intermittently conducted a research and development program to recover 227Ac and 228Th from neutron 

irradiated 226Ra (EG&G 1995a). The three parent radionuclides of 227Ac, 226Ra and 228Th and their 

radioactive progeny were present in the irradiated material. The recovery operation was conducted in 

a special shielded process facility referred to as the old cave (room SW-19) on the east side of the 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 16 of 113

building. From 1951 to 1953 work in the cave resulted in the release of 1.6 E+05 uCi of 227Ac, 226Ra, 

228Th and their radioactive progeny (Story 1973). From 1964 to 1968, purified 227Ac in oxide and 

nitrate forms was processed in a hot cell and analytical lab area (Room SW-140) in the SW Building 

(EG&G 1995a). This work resulted in the release of 5.3 uCi of 227Ac to the atmosphere (Storey 1973). 

This facility has been demolished. 

Technical (T) Building 

The T Building was operational in 1949 and was originally used to purify 210Po for use in nuclear 

weapon initiators. Decontamination work was done from 1971 through 1974 on the 210Po processing 

areas. Its last mission was to support tritium programs for reconfiguration, safe shutdown, and 

remaining operations. The facility has also been used to extract radionuclides, to house the plutonium 

verification facility, and to store transuranic (TRU) materials. Since 1980, KYLE (classified), Tritium 

Emission Recovery Facility (TERF), Hydrogen Isotope Separations System (HISS), and other tritium 

facilities large enough to handle multikilogram quantities were added to T Building. Special nuclear 

material (SNM), primarily 239Pu, was stored in T-Building storage areas A and B prior to transfer to 

Building 38 for repackaging. The SNM was in the form of metal, metal oxide, residue, and/or 

combinations thereof; these materials were contained in sealed drums and other metal containers.

Building 38 

Building 38 was originally designed to be a radiochemical processing facility for 238Pu, used in the 

oxide form as fuel for radioisotope thermoelectric generators (RTGs). Building design began in 1965, 

and construction was complete in December 1967. Assembly and disassembly associated with 

manufacturing 238Pu heat source modules for RTGs were the primary operations conducted in 

Building 38. Other programs included assembly of three types of heat sources and two types of 

RTGs and general-purpose radionuclide handling. RTG and heat source assembly and disassembly, 

which were supported in the F-line operations, involved the 5-watt, High Power Generator Mod 3 and 

General Purpose Heat Sources (GPHS) programs.

Building 50 

Building 50 was an RTG assembly and test laboratory. Encapsulated 238Pu fuel was loaded into 

graphite assemblies in Building 38 and welded into stainless-steel containers. The containers were 

transferred to Building 50 for fuel reduction and subsequent installation in electrical converters. 

Building 22, Waste Staging Facility

The Waste Staging Facility (WSF) provides storage and staging for solid low-level radioactive waste 

(LLW) containers prior to offsite shipment. The facility can store as many as 186 metal boxes, stage 

lined and unlined 30- or 55-gallon metal drums with or without overpack, and stage closed wooden 

boxes that contain LLW. Transition to the WSF was complete in June 1995. Building 22, built in 

1967, previously housed a property management warehouse, office spaces, and a test facility for 

glovebox operations. 

Building 72 

Building 72 is used to store miscellaneous hazardous wastes until they can be shipped off the site for 

disposal. The wastes are in steel drums, plastic drums, plastic and steel containers of various sizes, 

and gas cylinders. In addition, waste sampling, packaging, and repackaging of some wastes; drum 

over packing; and container inspection and marking occur in this facility. Building 72 is a steel-framed 

building with metal panel siding on three walls.

Table 4-10 lists significant programs and events that occurred at the Mound site that are potentially 

relevant to dose reconstruction.

Most early programs were concerned with 210Po and its applications, particularly the fabrication of 

neutron and alpha sources for weapon and nonweapon use. From 1950 to 1963, laboratory 

investigations of uranium, 231Pa, and 239Pu were part of the national civilian power reactor program. 

Separation of stable isotopes of noble gases began in 1954. Also in 1954, Mound scientists invented 

the thermoelectric generator fueled with 210Po. A limited amount of research and development work 

with 239Pu in gram quantities began in 1955. In 1957, Mound Laboratory began the development, 

production, and surveillance of detonators for military applications. Beginning in 1959, 238Pu in

Mound Laboratory received 400 tons of thorium (232Th) sludge from Brazilian ore residues, which 

was subsequently stored outdoors in 55-gallon drums. 

1955 Repackaging of 6,000 55-gallon drums containing thorium ore and sludge occurred through 1965 at 

three different times to help prevent possibility of further contamination. In 1964, the thorium sludge 

was transferred to a special building for storage. Early in 1975, the thorium ore residues were 

removed from Mound and sold to a commercial organization.

quantities up to a kilogram was used in research, development, and production operations; however, 

the Summary of Environmental Monitoring Report for 1959 and First Quarter 1960, states that “during 

the year 1959, a year of transition, the alpha emitting isotope that would have contributed to 

environmental background was polonium” (Monsanto,1960). 

From 1959 to 1960, the initial plutonium program activities were conducted in R Building. During this 

early phase, the program consisted of research and development efforts to understand the chemistry 

and metallurgy of 238Pu. The thermal hazards as well as the chemical reactivity and containment of 

plutonium during processing and fabrication led to major safety concerns. 

In 1960, the SM Building was constructed to provide both the technical and safety related features 

that were absent in the R Building. The elevated emissions of plutonium (see section 4.2.2) in 1960 

were due to R Building operations. The SM Building became operational in 1961 and emissions of 

plutonium decreased significantly (see section 4.2.2). In 1967, Building 38 (also known as the PP 

Building) and an annex on the WD Building were constructed to take over the increased plutonium 

program demands. The SM Building processes and fabrication operations were transferred to the 

new Building 38 facility. 

The total quantity of 238Pu used in operations at Mound Laboratory was sharply reduced in June 1977. 

Encapsulation of 238Pu for the large heat sources (containing in some cases more than 4 kilograms of 

this material) was terminated. In late 1979, Mound ended production of plutonium oxide feedstock for 

heat sources, and began receiving this material already in primary encapsulation.

4.2.1 Environmental Air Monitoring

Mound Laboratory had various environmental air-monitoring programs through most of its history, 

starting in 1948 and continuing to the present. Gross alpha, tritiated water vapor (HTO), 210Po, 238Pu, 

239, 240Pu, 228Th, 230Th, and 232Th measurements occurred during these years, although not all 

measurements were collected in any given year. The tables in Attachments 4B, 4C, and 4D list 

environmental air-monitoring data from 1948 to September 1959, 1959 to 1972, and 1973 to 2001, 

respectively, along with references for the data. 

From 1948 to 1959, air monitoring consisted of offsite, downwind air samples taken at unspecified 

locations and counted for gross alpha radiation. From 1960 to 1966, Mound conducted roving air 

sampler measurements of gross alpha activity obtained by truck-mounted equipment driven over a 

planned route in areas adjacent to the Mound site. From 1967 to 1971, Mound monitored 

concentrations of HTO, 238Pu, and 210Po off the site. Available data do not contain onsite air-sampling 

data for these three periods (with the exception of 1971, when “Site Center, Southern and Northern 

Perimeter” data was acquired). The usefulness of the offsite data prior to 1971 is limited, because the 

air samples were not collected in one location around the clock. Therefore, it is not certain whether 

the offsite concentrations reflect a maximum or even average concentration. Consequently, the 

offsite data cannot be used to infer onsite airborne radionuclide concentrations. 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 19 of 113

A program to acquire onsite meteorological data began in 1972 (Monsanto 1976a). The average 

onsite wind speed was approximately 8 mph (13 km/h) and the predominant wind direction was from 

the southwest. From 1972 to 2002, air-monitoring data was obtained from a network of both onsite 

(Figure 4-1) and offsite (Figure 4-2) stationary air samplers. This analysis used the site-wide median 

air concentration from the annual average onsite air monitoring station results to determine intake

concentrations from 1971 through 2003 (See Tables 4C-13, 4C-14, and 4D-1 through 4D-29). For 

years in which onsite air monitoring data were unavailable (prior to 1971) and effluent data was 

available, empirically derived onsite atmospheric dispersion factors (plutonium, polonium particulates, 

and hydrogen gas/vapor χ/Qs) were used to estimate the intake air concentration. Table 4-11 

summarizes the annual, median effluent air concentrations used to derive intakes for dose 

reconstruction. Subsequent sections discuss the intakes estimated from these data and effluent 

release monitoring data.

Some of the environmental air monitoring station results (See Tables 4C-13, 4C-14, and 4D-1 through 

4D-30) were reported as “incremental” to reflect that the measured “environmental level” 

concentration at the control (28 miles upwind) location was subtracted from the concentration at the 

monitoring stations. Consequently, whenever nonincremental concentration results were reported, 

the contribution from control location No. 119 was subtracted from the site-wide median results. For 

all years in which on-site environmental air-monitoring data were available, the median concentration 

from the onsite annual average monitoring station results was selected to assign radionuclide intakes. 

For years in which onsite air monitoring data were unavailable (prior to 1971) and effluent data was 

available, empirically derived onsite atmospheric dispersion factors (plutonium, polonium particulates, 

and hydrogen gas/vapor χ/Qs) were used to estimate the onsite intake air concentration.

In 1997 Mound Laboratory added 232Th, 230Th and 228Th to the environmental air filter analyses 

conducted as part of the routine environmental air monitoring program in support of several D&D 

projects involving thorium contaminated soil and structures. Although these radionuclides are not 

effluents, the median of the annual average, environmental air-monitoring station results for 232Th, 

230Th and 228Th have been included in this section.

To account for trace radionuclides that were not included in the routine environmental air or effluent 

discharge sampling and analysis programs at Mound, 238Pu scaling factors were developed based on 

an assay of the feed material, plutonium dioxide, supplied to the Mound facility from SRS, as shown 

below. As a result, the scaling factor (activity concentration ratio) table (Table 4-12) infers 

concentrations of trace radionuclides and 239, 240Pu for years in which effluent or air monitoring station 

data only include 238Pu.

The feed material profile discussed above was adjusted to reflect the actual observed air sample ratio 

of 238Pu to 239, 240Pu to infer the 239, 240Pu concentration in air for years in which only 238Pu data were 

available. The actual activity concentration ratio for 239, 240Pu was inferred from measurements of air 

samples taken by Mound for the 1975 through 1980 period of record (See Table 4-13.). The 

observed ratio of 238Pu to 239, 240Pu in air samples from onsite sampling stations recording the highest 

annual average plutonium concentration from 1975 to 1980 is 31.0 to 1 compared to the theoretical 

ratio of 824 (i.e., the inverse of the theoretical 239, 240Pu activity concentration shown above). The 

discrepancy between the feed material ratio of 238Pu to 239, 240Pu and the observed air sample ratio of 

238Pu to 239, 240Pu is likely the result of 239,240 Pu effluent emissions associated with 239, 240 Pu research 

rather than the SRS feed material profile.

The relative internal dose contribution from radionuclides present in SRS plutonium dioxide feed 

material has been assessed using ICRP Publication 68 dose conversion factors (DCFs), as discussed 

below (ICRP 1995). Most of the internal dose (99.8%) is attributable to 238Pu (96.5 %) and 239,240Pu 

(3.3%). As a result, dose reconstructors can neglect the internal dose contribution from trace 

radionuclides other than 239,240Pu in effluent associated with the feed material. See Table 4-14.

a. Data from Attachment 4D, Tables 4D-3 through 4D-8.

For years in which onsite air monitoring data were unavailable (prior to 1971) and total, annual, stack 

effluent data was available, empirically derived onsite atmospheric dispersion factors (plutonium, 

polonium particulates, and hydrogen gas/vapor χ/Qs) were used to estimate the intake air 

concentration. 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 22 of 113

The χ/Q derivation coupled the site-wide median air concentration (238Pu, 210Po, and 3H concentration) 

with the corresponding total, annual, effluent discharges (Table 4-15). This derivation was repeated

for an 11-year period of record (1973 to 1983) for plutonium and HTO, and 1 year (1973) for 

polonium. For assigning an intake concentration, the 11- and 1-year average χ/Q was selected: 

8.61E-05 sec/m3 for plutonium, 5.12E-04 sec/m3 for polonium, and 2.56E-07sec/m3 for tritium (Table 

4-16). The calculated dispersion factor data for the 11- and 1-year period are presented in Table 4-16 

below. 

Polonium production and research at Mound were discontinued in the early 1970s (DOE 1993b). 

Polonium effluent discharge data are available only for 1953, 1973 and 1974; as a result, the ratio of 

210Po to 238Pu observed in environmental air samples has been used to infer the 210Po effluent release 

rate from 1967 through 1970. In addition, the 1973 and 1974 onsite polonium air monitoring results 

were influenced by the decontamination and decommissioning of the Mound polonium processing 

facilities (DOE 1993b). Consequently, the 1974 polonium effluent and air monitoring results shown in 

Table 4-16 were not used in the χ/Q derivation for polonium.

4.2.2 Effluent Intake Concentrations

The following discussion describes the technical approach used to establish airborne radionuclide 

concentrations to determine radionuclide intakes (Section 4.2.3) and submersion exposures (Section 

4.2.4). Section 4.2.5 describes the technical approach and results for the contaminated soil exposure 

pathways. These exposure pathways are (1) resuspension intakes, (2) external submersion, and (3) 

direct external from the contaminated soil layer.

For 238Pu, the effluent concentration data from 2001 through 1971 are based on the median, onsite 

annual environmental air monitoring results. From 1960 through 1970, the effluent concentration data 

are based on the reported 238Pu annual effluent source term from Table 4-15 combined with the 

derived atmospheric dispersion factor for 238Pu from Table 4-16 to infer the median onsite 

environmental concentration.

For 210Po, the effluent concentration data from 1971 through 1974 are based on the median, onsite 

annual environmental air monitoring results. From 1967 through 1970, the data are based on 

reported 238Pu annual effluent source terms (scaled to infer 210Po based on the ratio of 210Po to 238Pu 

on air samples) combined with the derived atmospheric dispersion factor for polonium from Table 4-

15 to infer median onsite environmental concentrations. As previously discussed, polonium effluent 

discharge data are available for only 1953, 1973 and 1974; consequently, from 1949 through 1953, it 

is assumed that the 210Po effluent source term remained constant at the 20-μCi per day level (Bradley 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 25 of 113

1953a). From 1954 through 1966, it is assumed that the 210Po release rate increased 20% each year 

from the constant 1949 through 1953 daily values (Table 4-15). This annual increase was considered 

necessary and reasonable to extrapolate between 1953 and 1967 effluent release rates. The 1949 

through 1966 210Po annual effluent source terms were combined with the atmospheric dispersion 

factor derived for polonium (Table 4-16) to infer onsite environmental concentrations.

monitoring results. Beginning in 1959 through 1970, the data are based on reported tritium effluent 

source terms (Table 4-15) combined with derived atmospheric dispersion factor derived for tritium in 

Table 4-16 to infer onsite environmental concentrations. From 1954 through 1958, it is assumed that 

the HTO release rate decreased 10% each year from that for 1959 (31,527 Ci/yr). From 1954 through 

1958, the HTO annual effluent source terms were combined with derived atmospheric dispersion 

factor for tritium to infer onsite median environmental concentrations. 

Table 4-11 lists the annual, average, effluent median intake concentrations used to calculate annual 

claimant intakes described in Section 4.2.3.

From 1951 through 1953 Mound intermittently conducted a research and development program to 

recover 227Ac, 226Ra and 228Th from neutron irradiated 226Ra. The three parent radionuclides of 227Ac, 

226Ra and 228Th and their radioactive progeny were present in the irradiated material. The recovery 

operation was conducted in a special shielded process facility referred to as the old cave (room SW19) on the east side of the building (EG&G 1995a). From 1951 to 1953 work in the cave resulted in 

the release of 1.6E+05 uCi of 227Ac, 226Ra, 228Th and their radioactive progeny (Story 1973). At the 

completion of the program 47.5 Ci of 226Ra, 14.9 Ci of 227Ac, and 24.6 Ci of 228Th were purified. 

Health Physics Monthly Information Reports prior to September 1952 do not contain useful air sample 

or effluent data from the Ra-Ac Program work areas. Beginning in September 1952, most of the 

Monthly and Quarterly Health Physics Reports contain a summary of the monthly average of initial air 

filter counts and a summary of the monthly average of final air filter counts performed between 20 to 

30 days after the initial count. Initial and final air sample counting data from high risk Ra-Ac work 

areas is presented in Table 4-17 below. This data has been used to calculate the release rate of long

assuming that equal quantities were released each year from 1951 through 1953 and assuming that 

the long lived radionuclides consisted of 227Ac, 226Ra, and 228Th in the same proportion as the amounts 

purified at the completion the program ( 55% 226Ra, 17% 227Ac, and 28% 228Th).

The median site-wide intake concentrations of 227Ac, 226Ra, and 228Th presented in Table 4-11 have 

been calculated assuming that the T west polonium stack was the source of the emissions with a 

dispersion factor (χ/Q) of 5.12E-04 sec/m3

. 

From 1964 through 1968, purified 227Ac in oxide and nitrate forms was processed in a hot cell and 

analytical lab area (Room SW-140) in the SW Building (EG&G 1995a). This work resulted in the 

release of 5.3 uCi of 227Ac to the atmosphere (Storey 1973). 

The median site-wide concentration of 227Ac presented in Table 4-11 has been calculated assuming 

that equal quantities were released each year from 1964 through 1968 from the T west polonium 

stack with a dispersion factor (χ/Q) of 5.12E-04sec/m3

. 

4.2.3 Mound Effluent Inhalation Intakes

4.2.3.1 Site-Wide Annual Median Effluent Radionuclide Inhalation Intakes 

The site-wide annual median radionuclide intakes presented in Table 4-18 are derived by multiplying 

the annual median effluent air concentrations (Table 4-11) by 2,400 m3

/yr, which is the product of 

reference man’s default breathing rate (1.2 m3

/hr) and 2,000 work hr/yr. The tritium intake has been 

increased by a factor of 1.5 to account for skin absorption. As discussed above, most of the internal 

dose (99.8%) from SRS feed material is attributable to 238Pu and 239,240Pu. As a result, only intakes of 

238Pu, 239,240Pu, HTO, 210Po, 232Th, 230Th, 228Th, 226Ra and 227Ac from Mound effluents are significant for 

dose reconstruction. The most claimant favorable absorption type should be chosen for dose 

reconstruction because of the various chemical forms of polonium, thorium and plutonium used at 

Mound Laboratory.

4.2.3.2 Site-Wide Maximum Annual Average Effluent Inhalation Intakes

Site-wide maximum, annual radionucluide intakes have been calculated to estimate the upper 95th

percentile effluent intake. These intakes have been calculated in a similar manner as the median

intakes presented in Table 4-18 above. From 1971 to 2001, the maximum, annual average on-site air 

monitoring station results (Tables 4C-13, 4C-14, and 4D-1 through 4D-30) were used to determine 

intake concentrations.

For years in which onsite air monitoring data were unavailable (prior to 1971) and annual effluent data 

was available, empirically derived onsite atmospheric dispersion factors (plutonium, polonium 

particulates, and hydrogen gas/vapor χ/Qs) were used to estimate the intake air concentration. The 

χ/Q derivation coupled the onsite air monitoring location indicating the highest

Table 4-19. Inferred maximum onsite dispersion 

factors by radionuclide, 1983–1973. 

annual, average air 

concentration (238Pu, 210Po, and 3

H concentration) with the corresponding effluent source term (shown 

in Table 4-16). This derivation was repeated for an 11-year period of record (1973 to 1983) for 

plutonium and HTO, and 1 year (1973) for polonium. For assigning an intake concentration, the 11- 

and 1-year average χ/Q was selected: 6.03E-04 sec/m3 for plutonium, 7.43E-04 sec/m3 for polonium, 

actinium and thorium and 5.90E-07 sec/m3 for gases/vapors (e.g. HT/HTO). The dispersion factor 

data used to infer maximum, annual average radionuclide intakes are presented in Table 4-19 below. 

The maximum intakes shown in Table 4-20 have been derived by multiplying the maximum, site-wide, 

annual average effluent air concentrations by 2,400 m3

/yr, which is the product of reference man’s 

default breathing rate (1.2 m3

/hr) and 2,000 work hr/yr. The tritium intake has been increased by a 

factor of 1.5 to account for skin absorption.

An estimate of the uncertainty associated with the median environmental intakes at Mound presented 

in Table 4-18 has been made by assuming that the intakes are lognormally distributed and that the 

median intakes represent the 50th percentile intake rate. The site-wide, maximum, annual average 

intakes presented in Table 4-20 are assumed to represent the upper 95th percentile intake. The 

resulting geometric standard deviations (GSDs) are presented in Table 4-21 below.

<EL – 50th percentile intake concentration is less than the environmental level measured 28 miles offsite.

4.2.4 Annual Effluent Submersion External Exposures

Annual average air submersion external exposures were calculated by multiplying the effluent air 

intake concentrations in Table 4-11 by 2,000 work hr/yr as shown in Table 4-22. To assess the 

magnitude of submersion dose, the values in Table 4-22 were multiplied by the effective dose 

coefficient for air submersion (Eckerman and Ryman 1993). The results of the assessment indicate 

that the annual effective submersion dose from all radionuclides in Mound effluents is less than 5.0 × 

10-10 Sv (<1 mrem) in any year during Mound operations. Consequently, dose reconstructors need 

not consider submersion dose from effluents. 

4.2.5 Resuspension Intakes, Submersion External Exposures, and Ground Layer External 

Exposures Attributed to Soil Contamination

This analysis estimated the intake of radionuclides resuspended from soil at the Mound facility using a 

site-wide average profile of radionuclide soil concentrations measured in 30-cm-thick soil samples 

(Lyons 2003). The analysis assumes that all the soil samples were obtained in 1990. In addition, the 

claiment favorable assumption that the soil contamination is the due to a combination of spills, 

pipeline breaks and effluent deposition in 1949 has been made. As a result, 1990 radionuclide 

concentrations were decay-corrected to obtain radionuclide activities present in 1949, 1950, 1955, 

1960, 1965, 1970, 1975, 1980 and 1985 to provide an estimate of radiological conditions for each 

time period (see Tables 4-23 through 4-28). No decay correction has been applied to radionuclides 

with a relatively long half-life or radionuclide progeny in secular equilibrium with a long-lived parent 

radionuclide present in the soil. Plutonium and Americium soil contamination from SRS feed material 

is assumed to be present beginning in 1960. 

Because there is no 210Po soil data available, the 210Po soil concentrations in Tables 4-23 through 4-

28 were inferred based on the relationship between the sum of 238Pu effluent from 1960 to 1983 

(362,670 uCi) and the decay corrected soil concentration of 238Pu in 1960 (2160.8 Bq/Kg). The 

resulting ratio of 5.96E-03 Bq/Kg per uCi emitted was applied to the 1949 through 1974 annual 210Po 

emissions. To account for the build up and decay of 210Po in soil, 16% of the previous years 210Po soil 

concentration was added to the next consecutive years 210Po soil concentration starting in 1950, 

because after one year, only 16% of the original 210Po activity remains. The highest 210Po soil 

concentration within the time periods shown in Tables 4-23 through 4-28 has been used in the 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 34 of 113

calculations. Because effluent emissions of 210Po at Mound ceased in 1974, 210Po soil contamination 

is assumed to have decayed by 1975. 

The mean soil concentrations (pCi g-1) were converted to resuspension concentrations using the fourfactor formula in ORAU (2003, equation 3-3). Resuspension air concentrations were used to 

calculate (1) external exposures by submersion and (2) submersion (resuspension) intakes (Bq) by 

multiplying the air concentrations by 2,000 h/yr and using a breathing rate of 2,400 m3

/y for inhalation 

intake. Resuspension intakes for 3

H, 238Pu, 239,240Pu and 210Po intakes were not calculated because 

the derivation of the inhalation intakes presented in Table 4-18 already accounts for soil resuspension 

intakes at the Mound site. The results are listed in Tables Tables 4-23 through 4-28 and are 

applicable (persist) for the periods indicated. 

The external submersion and submersion (resuspension) intakes are presented in Tables 4-23 

through 4-28. The annual external submersion dose and submersion (resuspension) intake doses 

due to contaminated soil are less than a 1 mrem annually and can be neglected for dose 

reconstruction. 

Estimates of external exposure from radionuclides present in soil at the Mound facility were made 

using the same site-wide average decay corrected profile of radionuclides included in the 

resuspension intake estimates. Soil mass activity concentrations were converted to equivalent 

volume activity concentrations using a soil density of 1,600 kg/m3 and exposure duration of 2,000 h/yr 

to derive soil layer external exposures. These results, (listed in Tables 4-23 through 4-28), are 

applicable to the radionuclides and periods applied to the resuspension intake assessment. Table 4-

29 summarizes the annual, mean, site-wide external exposure results for the Mound site.

No general area environmental measurements of direct gamma radiation were documented for the 

Mound facility other than a single aerial survey in July 1976 (DOE 1993). The maximum exposure 

rates documented in the survey report ranged from 20.5 to 23.5 μR h-1 around the SM Building and 

Building 38 on the SM/PP Hill. Data from this report were difficult to interpret in a manner useful to 

dose reconstruction because they (1) applied to a single moment in time and (2) were probably 

heavily influenced by isolated radiation sources. Nevertheless, this exposure rate has been used to 

estimate the maximum exposure rate on site by assuming that the maximum exposure rate of 23.5 μR 

h-1 measured in 1976 was due to a spill in 1949. The spill is assumed to contain a mix of 

radionuclides identical to the site wide, average soil profile of radionuclides measured in 30-cm thick 

soil samples (Lyons 2003). Consequently, the maximum exposure rate is assumed to decay over 

time exactly like the site wide, average soil concentrations (See Table 4-29).

An estimate of the uncertainty associated with the ambient dose from soil contamination has been 

made by assuming that the ambient dose is lognormally distributed and that the median annual dose 

from the soil contamination presented in Tables 4-23 through 4-28 represents the 50th percentile 

dose. The maximum annual exposure rates around the SM Building and Building 38 on the SM/PP 

Hill are assumed to represent the upper 95th percentile ambient dose. The resulting geometric 

standard deviation (GSD) is 3.12 for each year from 1949 through 2002. 

4.2.6 Direct External Exposure From Facilities 

No environmental measurements of direct gamma radiation were documented for the Mound facilities. 

Direct external ambient dose could have resulted from gamma radiation originating within the 

operational buildings at Mound or from the storage of waste material and or storage of irradiated 

bismuth slugs within facility buildings or onsite structures. The following discussion supports the 
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 35 of 113

conclusion that it is unlikely that gamma radiation originating from within the operational buildings of 

Mound contributed to the ambient environmental dose. 

Waste transport vehicles were used at Mound beginning in the 1950s for transporting casks of 

polonium from their unloading area along the railroad siding to the T Building. The irradiated canned 

bismuth slugs received from the Hanford site were removed from casks and stored in a pool of water 

located on the second floor of T Building where the separation of 210Po from bismuth took place (DOE 

1993b). 

Drummed radioactive wastes generated at Mound were typically staged in operating areas and 

moved by health physics personnel to storage warehouses before shipment. In the 1940s and 1950s 

the “old explosives bunkers” were used to store waste with high gamma radiation levels to avoid 

worker exposures. The isolated location of the bunkers allowed these wastes to be stored away from 

the occupied areas of the site. Modern facilities replaced the old warehouses onsite in the 1960s and 

1970s (DOE 1993b).

The most likely source of environmental exposure from gamma sources originating within Mound 

facilities would be associated with the 226Ra - 227Ac program which separated 227Ac from neutron

irradiated 226Ra target material. The radium-actinium technology developed at Argonne National Lab 

(ANL) was transferred to Mound in early 1950. The General Purpose building (GP) Building later 

known as the SW Building was constructed with a shielded process facility on the east side of the 

building referred to as the old cave. The cave design was duplicated from the one used at ANL. 

By March 1952, three radium – actinium separation runs had been completed in the cave. The first 

run contained 0.6 g of radium yielding 135 mCi of 227Ac. The second and third run contained 5 grams 

each and yielded 2.59 and 2.36 Ci of 227Ac respectively. Gamma surveys conducted during the runs 

indicated exposure rate levels varying from less than 1 mR/h in the operational area adjacent to the 

cave to 7 R/h inside the cave (Bradley and Burbage 1952b). Based on the survey results, it is unlikely 

that gamma radiation originating from within the SW Building cave contributed to the ambient 

environmental dose. 

No detailed description of the administrative practices involving environmental exposure is available 

for the early operating years at the Mound. Nevertheless, several 1951 Monthly Health Physics 

Reports state that whenever routine beta and gamma surveys in operational areas detect radiation 

levels greater than 7.5 mR/h, the area is either shielded or roped off (Bradley and Burbage 1951e, 

1951f, 1951g, 1951h, 1951i). Consequently, it is unlikely that gamma radiation originating from within 

the operational buildings of Mound contributed to the ambient environmental dose.

4.3 UNCERTAINTIES

An estimate of the uncertainty associated with the median environmental intakes at the Dayton 

Facilities and Mound Laboratory is presented in Section 4.1.2 and in Table 4-21. These estimates 

were made by assuming that the intakes are lognormally distributed and that the median intakes 

represent the 50th percentile intake rate. For the Dayton Facilities, the maximum permissible 210Po air 

concentration is assumed to represent the upper 95th percentile intake resulting in a GSD of 1.6. For 

Mound the calculated site-wide, annual maximum intakes presented in Table 4-20 are assumed to 

represent the upper 95th percentile intake. The resulting geometric standard deviations (GSDs) are 

presented in Table 4-21.

An estimate of the uncertainty associated with the ambient dose at the Dayton Facilities has been 

made by assuming that the ambient dose is lognormally distributed and that the median annual dose 

calculated in Section of 4.1.4.3 represents the 50th percentile dose. Exposure to the “tolerance” or 

permissible level of 15 cSv per year is assumed to represent the upper 95th percentile intake. The 

resulting geometric standard deviation (GSD) is 3.6. For Mound the calculated mean ambient dose 

presented in Table 4-29 is assumed to represent the 50th percentile dose. The maximum ambient 

dose associated with the SM/PP hill area is assumed to represent the upper 95th percentile ambient 

dose resulting in an annual GSD of 3.12.

Due to the lack of available environmental air monitoring data for Dayton Units III and IV, the 

environmental intakes for both Dayton Units were determined using the highest monthly median air 

concentration measured at Dayton Unit III in December 1947. Based on a review of available data, 

the environmental airborne 210Po at both facilities would likely be comparable. 

Effluent release rate data from Mound was unavailable for some operational time periods. 

Consequently, extrapolations were necessary to estimate intakes for years in which no onsite air 

monitoring data were available. Effluent intake data for 210Po from 1954 through 1966 were based on 

an assumption that the annual increase in the effluent release rate (source term) was 20% greater 

than the earliest year for which monitoring data were published (i.e., 20 μCi/d from 1949 through 

1953). Beginning in 1967 through 1970, the 210Po data are based on reported 238Pu effluent source 

terms (scaled to infer 210Po based on the ratio of 210Po to 238Pu on air filter samples). Similarly, annual 

tritium oxide intakes from 1954 through 1958 were backwards extrapolated from the 1959 source term 

(the first year for which such data were published—31,527 Ci/yr) using an annual assumed reduction 

factor of 10%. These assumptions are believed to be a reasonable depiction of the trend in facility 

operations during the extrapolated time frames, and the total activity released in effluent compares 

favorable to the inventory of released radionuclides reported by Mound presented below.

GLOSSARY

curie

A special unit of activity. One curie exactly equals 3.7 × 1010 nuclear transitions per second.

dose equivalent (H)

The product of the absorbed dose (D), the quality factor (Q), and any other modifying factors. 

The special unit is the rem. When D is expressed in Gy, H is in Sieverts (Sv). 

(1 Sv = 100 rem.)

dosimetry

The science of assessing absorbed dose, dose equivalent, effective dose equivalent, etc., 

from external and/or internal sources of radiation. 

exposure

As used in the technical sense, a measure expressed in roentgens (R) of the ionization 

produced by photon radiation (i.e., gamma and X-rays) in air. 

gamma rays (G or γ)

Electromagnetic radiation (photons) originating in atomic nuclei and accompanying many 

nuclear reactions (e.g., fission, radioactive decay, and neutron capture). Physically, gamma 

rays are identical to X-rays of high energy, the only essential difference being that X-rays do 

not originate in the nucleus. 

ionizing radiation

Electromagnetic or particulate radiation capable of producing charged particles through 

interactions with matter.

photon

A unit or "particle" of electromagnetic radiation consisting of X- and/or gamma rays. 

photon – X-ray

Electromagnetic radiation of energies between 10 keV and 100 keV whose source can be an 

X-ray machine or radionuclide.

radioisotope thermoelectric generator (RTG)

A power supply using thermoelectric unicouples to convert heat generated from radioactive 

decay to electricity.

radiation

Alpha, beta, neutron, and photon radiation. 

radioactivity

The spontaneous emission of radiation, generally alpha or beta particles, gamma rays, and 

neutrons from unstable nuclei.

rem

A unit of dose equivalent, equal to the product of the number of rad absorbed and the "quality 

factor."
Effective Date: 10/06/2004 Revision No. 00 Document No. ORAUT-TKBS-0016-4 Page 60 of 113

roentgen (R or r)

A unit of exposure to gamma (or X-ray) radiation. It is defined precisely as the quantity of 

gamma (or X) rays that will produce a total charge of 2.58 × 10-4 coulomb in 1 kg of dry air 

STP. An exposure of 1 R is approximately equivalent to an absorbed dose of 1 rad in soft 

tissue for higher (~>100 keV) energy photons.

shielding

A material or obstruction that absorbs (or attenuates) radiation and thus tends to protect 

personnel or materials from radiation.

X-ray

Ionizing electromagnetic radiation of external nuclear origin or a radiograph
