DOB ARCHIVES iT 7. -4- On the recommendation of the Working Group the FRC staff requested the NAS Advisory Committee to the FRC to suggest how the review of the basis for estimating risks associated with low levels of radiation exposure could best be accomplished. The committee met March 25, and will probably submit recommendations along the following lines: a. Yhe review could best be accomplished by an expansion of the present committee to include separate subcommittees on genetic effects, somatic effects, environmental effects with special reference to movement of radionuclides through the food chain, and how the resulting information can be used within the concept of a benefit-risk balance. b. The review should be conducted according to the highest standards of scientific inquiry over a period of about 2 years. c. The discussion showed the committee's concern that if public policy involving radiation is not to be made in a social vacuum there is a need to have similar estimates of the potential biological costs of other agents including chemical and chemical mutagens as these might affect man and his environment. However, the committee recognized that their expertise did not encompass such a broad examination.
