A comprehensive 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 problems. The Director, Division of Operational Safety, appointed a Task Group and through it staff liaison representatives of DNA, DOI and EPA were kept informed of progress toward completion of | recommendations. Current radiation protection guidance containing numerical standards and radiation protection philosophy of national and international standards bodies was used to develop recommended criteria: rn Population.dose to the Enewetak peopleshouldlow practicable. ° 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 for gonadal exposure to allow for uncertainties in dose pre- eh we ee dictions.
