—, agencies at an interagency meeting on September 7, 1972, 18 follows: AEC-radciological survey and cleaaup and rehabviitation criteria: Defense (through DNA) - cleanup; and DOI - rehabilitation and resettlement. EPA opted not to become involved formally, but agreed to advise and assist. During September 1972 to March 1974, AEC conducted an extensive radiological survey. A Task Group was established to evaluate the survey resuits and to prepare recommendations for cleanup and rehabilitation. The Task Group report was coordinated with DNA, DOI, and EPA, SECY 74-542, Outline of a Staif Paper on Enewetak Atoll, was discussed with the Commis- sion at Session 74-74 on April 23, 1974. The Commission generally accepted the proposed staff rationale which would allow the people to occupy part of the Atoll with certain practical restrictions on living sites, food sources, etc. This is consistent with the staff position that exposures should be ''as low as practicable" and based on conservative interpretation of Federal Radiation Council (FRC) guidelines. The Task Group report is available in the Secretariat and is summarized in Appendix 2. Key conciusions and recommendations are as foilows: (1) FRC guides for whole body, bone, ana gonads for the individual, and the philosophy of Alternative (3) should be used to evaluate predicted radiation doses. Owing to uncertainties in dose estimates, the vaiues used to evaluate cleanup alternatives were the FRC guides reduced by 50 percent for annuai doses to individuals and by 20 percent for the 30-year gonadal doses.
