diy syLi July 9, 1974 SUMMARY OF TASK GROUP RECOMMENDATIONS AQSOOS ENEWETAK ATOLL INTRODUCTION The Atomic Energy Commission agreed to provide radiological criteria for cleanup and rehabilitation of Enewetak Atoll to the Department of Defense (DOD) and to the Department of the Interior (DOI), A comprenensive survey of the radiological environment of Enewetak was made to serve as a basis for judgements and recommendations. The survey data show that the northern islands have the greater amount of radioactive contamination and there are plutonium probiems. The Director, Division of Operational Safety, appointed a Task Group and through it staif lieison representatives of DNA, DOI and EPA were kept informed of progress toward completion ci recormmendations. Current radiation pretection guidance containing numerical standerds and radiation proveciion philosophyof nztional and international standards bodies was used to develop recommended criteria: . . Population dose to the Enewetak people should be as low as practicable. The Federal Rediation Council (FRC) Radiation Protection Guides (RPG) for individual and gonadal exposures wiil be used to evaluate expcsure options. The values should be reduced by 50 percent for individual exposure and 20 percent for gonadal exposure to allow for uncertainties in dose predictions. The guides for cleanup planning become: Exposure Whole body and bone marrow Thyroid Bone Gonads 0.25 Rem/yr 0.75 Rem/yr 0.75 Rem/yr 4 Rem in 30 yr BE T POPYAVAILABpe APPENDIX 2 Cowen, 33 Q BR SA VOR 3 - \G my - ,
