The Honorable Marge Roukema United States House of Representatives l
Washington, D.C.
20615 I
Dear Congresswoman Roukema:
L This letter is in response to your letter of May 27, 1986, to Chainnan j
Palladino.
Your letter enclosed a letter from your constituent, Mr. Sidney Goodman, which included a copy of Mr. Goodman's letter to the Secretary of the l
Commission providing coments or, our proposed revision to the NRC regulations, l
Standards for Protection Against Radiation (10 CFR Part 20). I want to assure you that Mr. Goodman's coments will be carefully considered along with the t
other comments received on the Part 20 rulemaking.
9 Your letter asked us to provide you with information on the proposed new regulations. You specifically requested information on the differences in permissible radiation exposure levels between the new regulations and previous maximum levels. Enclosed is a copy of the Federal Register notice on the proposed rule which includes the complete text of the proposed revision to 10 CFR 20.
I would like to call your attention to Table 1 (pages 1095 - 1100) which provides a comparison of the proposed rule and the present Part 20.
i The changes in the concentration limits for radionuclides result from a new i
method of estimating doses and potential health risks that was recomended by i
the International Comission on Radiological Protection and Measurement in i
1977. Using this method, the risk of potential health effects associated with t
the intake limit for each radionuclide would be the same and be equivalent to i
the risk from the external dose limit. To achieve consistency and compatibility with this limit, it is necessary to lower the limits for some radionuclides and to raise the limits for others in accordance with current j
radiobiological information. With such a consistent system of limits, it is l
.technjcally feasible to ensure that the risk from internal and external sources when added together does not exceed the risk associated with 5 rems per year of j
external radiation. This will be an improvement over the present Part 20 where j
doses from radioactive materials inside the body are controlled separately from j
doses from radiation sources outside of the body.
