What is Federal guidance?
Federal guidance is a set of guidelines developed by EPA, for use by Federal and State agencies responsible for protecting the public from the harmful effects of radiation. Federal guidance helps protect both the general public and the people who work with and around radiation every day. There are two kinds of Federal guidance publications:
Who develops Federal guidance?
Who uses Federal guidance?
Federal guidance is developed for use by Federal and State agencies in the development of radiation rules and regulations that affect public health.
How does EPA develop Federal guidance?
To develop these documents and reports EPA:
What is the difference between the guidance documents and the technical reports?
Must Federal and State agencies follow the Federal guidance?
Since these are guidance documents not regulations, they are not legally enforceable. Federal and State agencies have the authority to determine the details of their own regulations. You should treat the Federal guidance recommendations and technical reports as basic guidelines.

EPA has developed these cancer slope factors for ingestion, inhalation and external exposure to radionuclides in units of picocuries (pCi).

Draft Blue Book - EPA Radiogenic Cancer Risk Models and Projections for the U.S. Population(116pp, 513Kb [about pdf format ])The National Research Council of the National Academy of Sciences released a report on the health risks from exposure to low levels of ionizing radiation in 2006. Cosponsored by the EPA and several other federal agencies, Health Risks from Exposure to Low Levels of Ionizing Radiation BEIR VII Phase 2 (BEIR VII) primarily addresses cancer and genetic risks from low doses of low-LET radiation (high energy photons and electrons).
The draft Blue Book is a proposed revision to EPA's methodology for estimating radiogenic cancers, based on the contents of the National Research Council's BEIR VII report and some ancillary information. It takes into account the Science Advisory Board's advisory review comments on the white paper below.

This guidance provides general principles, and specifies the numerical primary guides for limiting worker exposure. It applies to all workers who are exposed to radiation in the course of their work, either as employees of institutions and companies subject to Federal regulation or as Federal employees.
This guidance provides recommendations to reduce radiation exposure from the use of diagnostic x-rays. These recommendations, transmitted to the President jointly by EPA and the Department of Health, Education and Welfare (HEW), were based on two guiding principles: avoidance of unnecessary prescription of x-rays, and use of good technique to minimize radiation exposure.
This guidance sets forth recommendations for radiation protection activities as they apply to the underground mining of uranium ore. EPA subsequently reviewed these recommendations and concluded that no modification was necessary.
This guidance presents recommendations for population groups exposed to environmental sources of radiation. It provides Radiation Protection Guides; guidance on general principles of control applicable to all environmental radionuclides; and specific guidance in connection with exposure of population groups to radium-226, iodine-131, strontium-90, and strontium-89.
This guidance provides a general framework for radiation protection and general principles of radiation control based on the annual intake of radioactive materials. These recommendations provide the basis for the control and regulation of radiation exposure during normal peacetime operations. Numerical values for the Radiation Protection Guides, designed to limit the exposure of the whole body and certain organs, are provided.

|Federal Guidance Report No. 13 (Final)||Cancer Risk Coefficients for Environmental Exposure to Radionuclides, EPA 402-R-99-001 |
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.

This report provides tables of exposure-to-dose conversion factors for external exposure to photons and electrons emitted by radionuclides in air, water, and soil. It is intended to be a companion to Federal Guidance Report No. 11. The dose coefficients for exposure to external radiation are intended for the use of Federal agencies in calculating the dose equivalent to organs and tissues of the body. Dose coefficients for air submersion in Report No.12 update those given in Report No. 11. [back to top]
|Report No.11||Limiting Values of Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation, Submersion, and Ingestion, Environmental Protection Agency 520/1-88-020 September 1988.|
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. [back to top]
