Standard Operating Procedure

RA03 – Standardized Radiation Dose Assessment Reports and Dose 

Calculation Worksheets

1. Purpose/Summary

This standard operating procedure (SOP) provides detailed guidance on preparing 

standardized RDA Reports and dose calculation worksheets for Nuclear Test Personnel 

Review (NTPR) Program participants (generally veterans). Templates of a standardized 

RDA Report and Mathcad calculation worksheet are provided as attachments. The 

standardized templates are intended to help streamline the preparation of NTPR RDA 

reports, provide consistently organized content and facilitate the review process. They are 

also intended to minimize repetition of information provided either in the Scenario of 

Participation and Radiation Exposure (SPARE) or in the NTPR Dose Assessment SOP 

Manual. 

This SOP is written for qualified radiation dose analysts (“Analysts”) who develop RDA 

Reports and supporting dose calculation worksheets or perform detailed quality control of 

such, and for managers who oversee the entire dose assessment process to assure 

conformance with procedures, methods, quality standards of assessment products, and 

established NTPR policies and guidelines.

2. Scope

This SOP applies to all radiation dose assessments prepared according to SOP RA01

(found elsewhere in this SOP Manual). It provides guidance on the drafting of RDA 

Reports and stipulates a standard outline and format for calculation worksheets (currently 

developed using the Mathcad software) that guarantees the application of approved 

standard procedures and methods, and all documented data and information. It assures 

that all aspects of radiation dose calculations and reporting are addressed to satisfy the 

requirements of Title 32, Code of Federal Regulations (CFR), Part 218, Guidance for the 

Determination and Reporting of Nuclear Radiation Dose for DoD Participants in the 

Atmospheric Nuclear Test Program (DoD, 2020), DTRA’s NTPR Program Quality 

Assurance SOP (DTRA, 2021), and DTRA’s NTPR Program Support and Management 

SOP (DTRA, 2020). 

3. Responsibilities 

RDA Reports and accompanying calculation worksheets are prepared by Analysts and 

checked for quality and consistency by reviewers from the radiation dose assessment 

team and managers. Analysts draft RDA Reports and develop calculation worksheets that 

assist in determining radiation doses according to the standard operating procedures and 

standard methods described elsewhere in this procedures manual. Analysts are qualified

technical staff experienced in carrying out radiation dose assessments and trained in all 

procedures and methods relevant to the cases they prepare. 

4. Definitions

SPARE A document with detailed information on an NTPR participant’s activity 

scenario during involvement in the U.S. atmospheric nuclear testing 

program.

Mathcad Desktop software for performing and documenting engineering and 

scientific calculations.

5. Procedure: Detailed Activity/Task Description

A dose assessment accomplishes the analyses needed to estimate all relevant radiation 

dose components. The final product of the dose assessment is the RDA Report, 

supporting calculation worksheets, and any additional analyst notes. 

The primary Analyst drafts the RDA Report, which provides a summary of the 

participant's activities, sources of potential radiation exposures, description of exposure 

pathways, and resulting accrued mean and upper-bound dose. The type of information 

included in the RDA Report and a standard RDA Report template are provided in this 

procedure. Also, the Analyst prepares calculations of radiation doses and upper bounds 

for all identified exposure scenario elements based on the SPARE (with consideration of 

any comments on the SPARE that the participant supplies). The Analyst uses a 

calculation worksheet that adheres to a standard outline and format described in this 

procedure. 

5.1 Radiation Dose Assessment Reports

The RDA Report is the formal documentation of the results of the dose assessment 

process (SOP RA01). The completed RDA Report is intended for submission to the 

veteran, claimant, or the Department of Veteran Affairs. A template of a standard RDA 

Report is enclosed as Attachment 1. The RDA Report should include the following 

information:

 A complete assessment summary table of the mean and upper-bound doses, including 

total external gamma and neutron doses, doses to organs from internally deposited 

radioactive materials (internal doses), and external doses to the skin as applicable

 A summary of the veteran’s participation and key activities relevant to potential 

exposure pathways and radiation environments

 A discussion and documentation of material changes with respect to the SPARE 

process that stems from the veteran’s verbal or written comments regarding his 

activities and radiation exposures
DTRA / NTPR - Standard Operating Procedures Manual

RA03 – Standardized RDA Reports and Dose Calculation Worksheets

Revision No.: 2.0

Date: April 30, 2021

Page 6 of 29

 Summary descriptions of the component doses for each exposure situation that 

comprises the veteran’s scenario for external and internal doses.

Additionally, the following conventions should be adhered to in preparing the RDA 

Report:

 If exposures occurred in different calendar years from more than one operation, the 

mean and upper-bound doses are assigned for each year separately. When exposure 

occurred from participation in a single operation that spanned two calendar years, all 

doses in the overall summary table should be assigned to the first year of exposure.

 Internal doses from alpha particles are reported separately from internal doses due to 

gamma and beta radiations, which are combined.

 In reporting skin doses, contributions from beta particles and gamma rays are 

combined.

 All reported doses (doses listed in the overall summary table) will be given to two 

significant figures, obtained by rounding up the third figure. Final calculated doses 

less than 0.001 rem are reported as “<0.001 rem” when provided in tables, and as

“less than 1 mrem” or “less than 0.001 rem” when reported in the text. 

5.2 Decision Summary Sheet for the RDA Report

An RDA Report Decision Summary Sheet (DSS) should be prepared for each case 

requiring the development of a full RDA. The DSS should contain a header with at a 

minimum the following information (a template is provided as Attachment 2):

 Date prepared and name of preparer

 Veteran’s name, rank, unit, duty station and dates of participation

 Affected internal organs and surrogate organs if necessary

 Whether dosimetry records/film badges are available if they cover the entire or partial 

periods of participation. 

The second section of the DSS should include the major decisions made to develop the 

dose assessment along with the rationale and assumptions used to reach the decisions,

and references related to each decision (Attachment 2). 

5.3 Dose Calculation Worksheets

Dose calculation worksheets for specific veteran cases prepared using the Mathcad or 

other similar scientific software should be organized according to a standard outline and 

format (a template is provided as Attachment 3). Calculation worksheets should adhere to 

the following principles:
DTRA / NTPR - Standard Operating Procedures Manual

RA03 – Standardized RDA Reports and Dose Calculation Worksheets

Revision No.: 2.0

Date: April 30, 2021

Page 7 of 29

 Consistency among cases to include the same section headings (see Attachment 3)

 Sections that do not apply to a case are included with the annotation “Not applicable 

to this case” or a similar note

 Identifying information for the veteran and case is presented on the first page of the 

worksheet 

 Only input, calculations, and results that are relevant to the case are included

 Large data sets are read-in from external input files 

 Data input values are displayed at the end of worksheets in a Data Annex section and 

not in the input and calculations sections

 All content has to fit on 1-page width throughout the worksheet; landscape or portrait 

orientation can be used

 Content including equations and text do not overlap page breaks.

6. Data and Records Management 

Official copies of final RDA Reports, the DSS, supporting dose calculations worksheets, 

and supporting information are maintained by the Enterprise Manager according to the 

NTPR Program Support and Management SOP (DTRA, 2020). 

7. Quality Control and Quality Assurance

This procedure assures that RDA Reports and dose calculation worksheets are prepared

according to the standardized document organization and formats as specified in 

revisions of this Standard Procedures Manual. All RDA Reports and calculation 

worksheets undergo the internal review process specified in SOP RA04. This process 

ensures that the products of a dose assessment are prepared according to this procedure 

and adhere to the standards set forth in the NTPR Quality Assurance SOP (DTRA, 2021).

These dose(s) are included in Table ##. 

[b.2- If dosimetry records are found and are all unreliable, include the following:] 

Because dosimetry records for the veteran were determined to be unreliable, i.e., do not represent 

true doses due to [include reason(s) for unreliability, such as environmental damage], his [/her]

external gamma doses are reconstructed using SOP RA02 and the methods described in SM

ED02 (DTRA, [year1]). 

[b.3- If dosimetry records are found and only some are unreliable, include the following:] 

Because dosimetry records from film badge number(s) [specify film badge number(s) with 

unreliable readings] for the veteran were determined to be unreliable due to [include reason(s) 

for unreliability, such as environmental damage], the external gamma doses corresponding to the 

periods and activities covered by these film badges are reconstructed using SOP RA02 and the 

methods described in SM ED02 (DTRA, [year1]). 

[c- If no dosimetry records were found, continue with the following:] 

As a result, his [/her] external gamma doses are reconstructed using SOP RA02 and the methods 

described in SM ED02 (DTRA, [year1]). 

Potential Sources of Exposure

The following sources of potential external radiation exposure are considered:

[List all applicable sources of potential exposure(s). The following are examples:]

 Initial gamma and neutron radiation from Operation [insert name of operation] detonations

 Residual gamma radiation from [insert name of operation or specific shots] fallout [and/or 

neutron-activated soil/material] on [insert location, e.g., name of an island at the PPG, ship 

or NTS location]

 Residual gamma radiation from [insert name of operation or specific shots] fallout [and/or 

neutron-activated soil/material] while [insert specific activity, e.g., “digging trenches”, 

“traveling on small boats”, “handling contaminated equipment”, etc.]

[Initial Radiation Exposures: If the veteran was exposed to initial neutron radiation, insert the 

following:]

Initial Radiation: [Insert statement reporting the initial neutron dose here; also include the dose 

in the external dose summary table.]

[If the veteran was not exposed to initial neutron and gamma radiations, insert the applicable 

statement from the following:]

Initial Radiation: the veteran was more than [insert number of miles] miles (mi) [/nautical miles

(nmi)] from each of the detonations. At such distances, he was not exposed to any measurable 

initial gamma or neutron radiation (DTRA, [year1], SM ED02). 

[or]

Prepared: [Insert Date Prepared]

Initial Radiation: the veteran was not in the test area for any of the detonations. Therefore, he 

was not exposed to initial gamma or neutron radiation (DTRA, [year1], SM ED02).

[Residual Radiation Exposures: discuss external residual radiation doses from each 

source/activity, as appropriate, for which a dose is reconstructed. The following are examples:] 

Residual Gamma Radiation from Fallout on [insert location, e.g., name of an island, ship, or 

NTS site]: Fallout from [insert operation/shot name(s)] detonations contributed to the radiation 

environment at [insert location] during the veteran’s presence in the test area (DTRA, [year1], 

Appendix X-#) and (DTRA, [year2]). Based on the peak radiation intensities at [insert location] 

reported for Shot(s) [insert shot names] (DTRA, [year1], Appendix X-#) and further assuming 

[include any additional assumptions, if necessary - e.g., the veteran spent up to 60 percent of his 

[/her] day outdoors], the veteran accrued a gamma dose of _____ rem. 

Residual Gamma Radiation from [include other applicable sources such as indicated above]:

† The veteran’s upper-bound external gamma dose is based on an uncertainty factor of 3 applied to each 

independent component of his [/her] reconstructed dose [insert the following only if film badge doses are used] 

and to other uncertainties inherent in his [/her] film badge readings. Uncertainties are combined using standard 

statistical methods. (DTRA, [year1], SM UA01). 

Internal Dose Assessment

Neither radio-bioassay nor air sampling data pertinent to the veteran were found. Fifty-year 

committed equivalent doses (CEDs) to internal body organs are determined from other 

radiological measurements using the methodologies and assumptions presented in SM ID01 

(DTRA, [year1]) and shot-specific radiochemistry data and standard assumptions given in 

Appendix X-# of the SOP Manual (DTRA, [year1]), unless indicated otherwise. 

[If some of the dose factors used are for surrogate organs, insert the following paragraph:]

The calculation of internal doses requires the selection of dose factors for the organs affected by 

the medical conditions, or their surrogates. The organs selected as surrogates for dose 

calculations that are relevant to the veteran’s medical conditions are 1) [insert surrogate organ]

for [insert medical condition #1], 2) [insert surrogate organ] for [insert medical condition #2], 

3) [and so on]. (SOP RA02, DTRA, [year1].)

The veteran is assumed to have accrued internal doses to his [/her] [insert organ name(s)]

concurrently with his [/her] accrual of the external gamma doses described above in “External 

Dose Assessment.” Therefore, his [/her] locations and activities as described above establish the 

radiological environment in which his [/her] intake of contaminated materials occurred. 

Potential Sources of Exposure 

The following source(s) of potential radiation exposure pathways to the veteran’s [insert organ

name(s)] are considered:

[List all applicable sources of potential exposure pathways. The following are examples:]

 Inhalation of both descending and subsequently resuspended [insert shot name(s)] fallout at 

[insert location name(s)]

 Inhalation of suspended [insert shot name(s)] neutron-activated soil/material at [insert 

location name(s)] while [insert specific activity, e.g., “digging trenches”, “handling 

contaminated equipment”, “traveling on small boats”, etc.]

 Ingestion of descending [insert shot name(s)] fallout at [insert location name(s)] 

 Incidental ingestion of contaminated soil and dust while at [insert land location name(s)] 

 [Other applicable sources of internal exposure, e.g., ingestion of seawater while swimming,

intake of contaminants on equipment contacted by the veteran, etc.]

Dose Assessment

[Discuss internal doses from each source/activity. The following are examples: (if the number of 

pathways/sources is large, consider reporting the doses in a table inserted at the end of the last 

exposure pathway description)] 

Inhalation of [insert name of operation/shot] Resuspended Fallout: during the veteran’s period 

of deployment at [insert location], he [/she] inhaled resuspended fallout from [identify 

detonation(s)]. The CEDs to the veteran’s [insert organ name (s)] resulting from the inhalation 

of resuspended fallout are _____ [or “less than 0.001”] rem from alpha radiation and _____ [or 

“less than 0.001”] rem from beta-plus-gamma radiation. 

Ingestion of Radioactive Materials: during the veteran’s deployment at [insert location], he 

ingested contaminated material from [enter sources from those identified above]. The CEDs to 

the veteran’s [insert organ name(s)] resulting from the ingestion of contaminated material are 

_____ [or “less than 0.001”] rem from alpha radiation and _____ [or “less than 0.001”] rem 

from beta-plus-gamma radiation.

Internal Dose Summary: the total rounded CEDs to the veteran’s [insert name of organ(s)] that 

resulted from all intakes of radioactive material during his [/her] participation in [insert name of 

operation] are presented in Table [###]. Applying an uncertainty factor of 10 [or other 

appropriate uncertainty factors as discussed in SM UA01] to the total mean internal doses results 

in the rounded upper-bound CEDs shown in Table [###]. (DTRA, [year1], SMs ID01 and

Skin Dose Assessment [If required]

The doses to the skin of the veteran’s [insert skin site(s)] are determined for the basal cell layer 

of the epidermis, which lies at an average depth of 70 micrometers below the surface of the skin. 

These doses are determined in accordance with SOP RA02 and SMs ED03 and ED04 (DTRA, 

[year1]). 

Potential Sources of Exposure 

The following source(s) of potential radiation exposure of the veteran’s [insert name(s) of skin 

site(s)] are considered: 

[List all applicable sources of potential exposures. The following are examples:]

 Radiation (beta and gamma) from ground-deposited fallout/neutron-activated soil/material at 

[insert location] while [insert specific activity, e.g., “digging trenches”, “traveling on small 

boats”, “handling contaminated equipment”, etc.]

 Radiation (beta and gamma) from contaminants resuspended from the ground or descending 

fallout at [insert location] which are deposited directly on the veteran’s skin or his [/her] 

clothing

 [Radiation from contamination (not already included) for specific activities, e.g., digging 

trenches, handling contaminated equipment, swimming in contaminated seawater, etc.]

Dose Assessment

[Discuss skin doses from each source/activity. The following are examples:] 

Ground-Deposited Fallout at [insert location, e.g., name of an island, etc.]: The skin of the 

veteran was exposed to radiation from [insert operation/shot names] fallout/neutron-activated 

soil. The veteran accrued beta and gamma doses simultaneously during the periods [insert dates 

of exposure]. The beta-plus-gamma doses to the skin of the veteran’s [insert name(s) of skin 

site(s)] from this source of radiation are [insert b+g dose for site #1], [insert b+g dose for 

site #2], and [insert b+g dose for site #3] rem, respectively. 

Contact Skin Contamination while Stationed at [insert location]: in addition to skin doses from 

fallout contaminants deposited on ground/ship surfaces, it is assumed that the veteran’s skin was 

contaminated by descending and resuspended fallout/neutron-activated soil that was deposited 

directly on the skin of his [/her] [insert name (s) of skin site(s)]. To maximize his [/her] skin 

doses, the veteran is assumed to have been outside for the entire duration of any episodes of 

descending fallout he experienced. Based on these assumptions, the total (beta-plus-gamma) 

doses to the veteran’s [insert skin site(s)] from contaminants that were deposited directly on the

skin from descending and resuspended fallout (/neutron-activated soil) while he [/she] was at 

[insert locations] during [insert dates] are [insert b+g dose for skin site #1], [insert b+g dose for 

skin site #2], and [insert b+g dose for skin site #3] rem, respectively. 

Skin Dose Summary: The total skin dose(s) to the veteran’s [insert skin site(s)] that resulted 

from exposure to radioactive material during his [/her] participation in [insert name of 

operation], are [insert total dose for skin site #1], [insert total dose for skin site #2], and [insert 

total dose for skin site #3] rem, respectively. The application of appropriate uncertainty factors

(DTRA, [year1], SM UA01) to each independent source of exposure results in upper-bound

doses to the skin of the veteran’s [insert name(s) of skin site(s)] of [insert upper-bound dose for 

skin site #1], [insert upper-bound dose for skin site #2], and [insert upper-bound dose for skin 

site #3] rem, respectively.

Lens of Eye Dose Assessment [If required]

The doses to the lens of the eye of the veteran are determined for the lens of the eye which lies at 

an average depth of 3 millimeters below the surface of the eye. These doses are determined in 

accordance with SOP RA02 and SM ED05 (DTRA, [year1]). 

Potential Sources of Exposure 

The following source(s) of potential radiation exposure of the veteran’s lens of the eye are 

considered: 

[List all applicable sources of potential exposures. The following are examples:]

 Residual beta and gamma radiation from ground-deposited fallout/neutron-activated 

soil/material at [insert location] 

 Beta radiation from dermal contamination of the eyelid (not already included) for specific 

activities, e.g., digging trenches, handling contaminated equipment, swimming in 

contaminated seawater, etc.]

Dose Assessment

[Discuss lens doses from each source/activity. The following are examples:] 

Residual beta and gamma radiation at [insert location, e.g., name of an island, etc.]:the lens of 

the eye of the veteran was exposed to radiation from [insert operation/shot names]

fallout/neutron-activated soil. The veteran accrued beta and gamma doses simultaneously during 

the periods [insert dates of exposure]. The beta-plus-gamma doses to the lens of the eye of the 

veteran from this source of radiation are [insert b+g dose for site #1], [insert b+g dose for 

site #2], and [insert b+g dose for site #3] rem, respectively. 

Dermal Contamination on Eyelid while Stationed at [insert location]: In addition to lens of the 

eye doses from fallout contaminants deposited on ground/ship surfaces, it is assumed that the 

veteran’s eyelid was contaminated by descending and resuspended fallout/neutron-activated soil

that was deposited directly on the eyelid of his [/her] [insert name (s) of skin site(s)].To 

maximize his [/her] lens of the eye dose, the veteran is assumed to have been outside for the 

entire duration of any episodes of descending fallout he experienced. Based on these 

assumptions, the total (beta-plus-gamma) doses to the veteran’s lends of the eye from 

contaminants that were deposited directly on the eyelid from descending and resuspended fallout

Prepared: [Insert Date Prepared]

(/neutron-activated soil) while he [/she] was at [insert locations] during [insert dates] are [insert 

b+g dose for skin site #1], [insert b+g dose for skin site #2], and [insert b+g dose for skin 

site #3] rem, respectively. 

Lens of the Eye Dose Summary: the total lens of the eye dose(s) that resulted from exposure to 

radioactive material during his [/her] participation in [insert name of operation], are [lens of the 

eye dose here] rem, respectively. The application of appropriate uncertainty factors (DTRA, 

[year1], SM UA01) to each independent source of exposure results in upper-bound doses to the 

lens of the veteran’s, is [total lens of the eye dose] rem, respectively.
