Report No. 13, Cancer Risk Coefficients for Environmental Exposure to Radionuclide: Updates and Supplements
Acute Dose Calculator
The Acute Dose Calculator is a program which calculates acute radiation doses from an oral inhalation intake of radionuclides. The calculation can be made for selected time periods after intake.
Below are two versions of the program: Acute Dose Calculator (Complete), which contains all files necessary to run the calculations and Acute Dose Calculator for use with the FGR 13 CD supplement, which allows the user to obtain two of the necessary files from the CD, rather than downloading them. Both versions contain a README file.

Final-Federal Guidance Report No. 13
Cancer Risk
Coefficients for Environmental Exposure to Radionuclides (PDF) [EPA 402-R-99-001] (335 pp, 3.13MB) September, 1999
This report provides methods and data for estimating risks due to both internal and external radionuclide exposures. It includes coefficients for assessing cancer risks from environmental exposure to about 800 radionuclides. Both mortality and incidence risk coefficients are tabulated for inhalation, food and water ingestion, submersion in air and exposure to uniform soil concentrations. The age-averaged coefficients consider age-specific intake rates, dose modeling, and risk modeling. The information presented
in this report is for use in assessing risks from radionuclide exposure in a variety of applications ranging from environmental
impact analyses of specific sites to the general analyses that support rulemaking.
Federal Guidance Report No.12
External Exposure to Radionuclides in Air, Water, and Soil (PDF) [EPA 402-R-93-81] (238 pp, 1,688K), 9/93
This Federal guidance report is the third of a series designed to provide technical information useful in implementing radiation protection programs. The dose coefficients in this report are intended for use by federal agencies having regulatory responsibilities for protection of members of the public and/or workers. We also encourage their use by State and local authorities.
Federal Guidance Report No. 11
Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation, Submersion, and Ingestion (PDF) [EPA 520/1-88-020] (224 pp, 25,942K), 9/88
This report provides derived guides (limiting values) of radionuclide intake and air concentration for control of occupational exposure that are consistent with 1987 Federal Guidance Document, Radiation Protection Guidance to Federal Agencies for Occupational Exposure. The derived guides serve as the basis for regulations setting upper bounds on the inhalation and ingestion of, and submersion in, radioactive materials in the workplace. The report also includes tables of exposure-to-dose conversion factors for general use in assessing average individual committed doses in any population that is adequately characterized by Reference Man (ICRP
1975). This report supercedes Federal Guidance Report No. 10.
Federal Guidance Report No.10
The Radioactivity Concentration Guides [EPA 520/1-84-010] 12/84
This report provides numerical values for the concentrations of radioactivity in air and water, corresponding to the limiting annual doses recommended for workers in the 1960 Federal Guidance Document, Radiation Protection Guidance for Federal Agencies.
Federal Guidance Report No. 9
Radiation Protection Guidance for Diagnostic X-rays (PDF) [EPA 520/4-76-019] (41 pp, 3,138K), 10/76
This report, which was prepared in cooperation with an Interagency Working Group on Medical Radiation formed on July 5, 1974, provides recommendations to the President for use by federal agencies in developing standards to reduce unnecessary radiation exposure due to medical uses of diagnostic x rays. It provides the basis for the federal guidance document, Radiation Protection Guidance to Federal Agencies for Diagnostic X-rays.
Background Report: Recommendations on Guidance for Diagnostic X-Ray Studies in Federal Health Care Facilities (PDF) [EPA 520/4-76-002] (38 pp, 872K), 3/76

This guidance provides background material used in the development of guidance for Federal agencies for (1) planning protective actions to reduce potential doses to the population from radioactive fission products which may contaminate food, and (2) doses at which implementation of protective actions may be appropriate.

Estimates and Evaluation of Fallout in the United States from Nuclear Weapons Testing Conducted Through 1962 (PDF) (34 pp, 1,131 K), Federal Radiation Council, 5/63
This report provides an analysis of the levels of fallout anticipated in 1963 and subsequent years following the programs of atmospheric nuclear weapons testing conducted through 1962. The report forecasts a substantial increase in the probable levels of radionuclides from fallout during 1963 with decreasing quantities in subsequent years.
Federal Guidance Report No. 3
Health Implications of Fallout from Nuclear Weapons Testing Through 1961 (PDF) (13pp, 504 K), Federal Radiation Council, 5/62
This report evaluates the health implication of fallout from nuclear weapons testing conducted through 1961. It concluded that nuclear testing through 1961 increased by small amounts the normal risks of adverse health effects to the general population.
Federal Guidance Report Report No. 2
Background Material for the Development of Radiation Protection Standards (PDF) (23pp, 370 K), Federal Radiation Council September, 1961
This report provides the background information for the 1961 Federal Guidance Document. It includes Radiation Protection Guides for certain organs of individuals in the general population, as well as averages over exposed populations.
Federal Guidance Report No. 1
Background Material for the Development of Radiation Protection Standards (PDF) (43 pp, 546 K), Federal Radiation Council, 5/60
This report provides the background information for the development of the 1960 and 1961 Federal Guidance Documents.
It introduced and defined the term "Radiation Protection Guide" (RPG). It provided numerical values for RPGs for the whole body and certain organs of radiation workers, and for the whole body of individuals in the general population as well as average population gonadal dose.
