AOSS7O July 9, 1974 SUMMARY OF TASK GROUP RECOMMENDATIONS ENEWETAK ATOLL INTRODUCTION The Atomic Energy Commission agreed to provide radiological criteria for cleam:ic and rehzbilitation of Enewetak Atoll to the Department of Defense (DOD) and to the Department of the Interior (DOI). A comprehensive survey of the radiological environment of Enewetak was made to serve as a basis for judge- ments and recommendations. The survey data show that the northern islands have the greater amount of radioactive contamination and there are plutonium problems. The Directer, Division of Operational Safety, appointed a Task Group and throughit staff liaison representatives of DNA, DOI and EPA were kept informed of progress toward completion of recommendations. Current radiation protection guidance containing ° Population dose to the Enewetak people should be as low as . The Federal Radiation Council (FRC) Radiation Protection Guides (RPG) for individual and gonadal exposures will be used to evaluate exposure options. The values should be reduced by 50 percent for individual exposure and 20 percent practicable. for gonadal exposure to ailow for uncertainties in dose pre- dictions. The guides for cleanup planning become: Exposure Whole body and bone marrow . 0.25 Rem/yr Gonads 4 Rem in 30 yr Thyroid Bone 0.75 Rem/yr 0.75 Rem/yr eee ee numerical standards and radiation protection philosophy of national and international standards bodies was used to develop recommended criteria:
