However, it is believed that any individual will not exceed a daily intake, averaged over a year, greater than two times the estimated average daily intake. (See Enclosure 1.) FEDERAL STANDARDS To comply with Federal Radiation Standards, certain conditions must be met. First, the average dose to the population should not exceed 170 mRem/Yr. Second, when the dose to individuals is known, the standard is 500 mRem/Yr. To comply with this requirement for Bikini Island residents the monitoring program to measure the dose to individuals was begun five years ago. Third, the dose to bone marrow of individuals should not exceed 500 mRem/Yr. Because of the way certain radionuclides are deposited in the body, bone marrow doses are expected to be higher than whole body doses. Thus, the bone marrow standard for individuals will probably be controlling at Bikini Atoll. Fourth, the average whole body dose over 30 years to the pop- ulation should not exceed 5,000 mRem. CALCULATED DOSE The calculation doses shown below are for two living patterns and for two assumed diets. The diets are based on the recent experience and observations of the scientific teams who have been working on Bikini Atoll. Calculated Maximum Annual Dose A. People live 100% of the time on Eneu Island With Food Imports Without Food Imports Whole Body 120 mRem/Yr. 210 mRem/Yr. Bone Marrow 140 mRem/Yr. 260 mRem/Yr. B. People live 80% of the time on Eneu Island and visit Bikini Island 20% of the time, but assumes no food from Bikini Island is eaten. With Food Imports Without Food Imports Whole Body 170 mRem/Yr. 260 mRem/Yr. Bone Marrow 190 mRem/Yr. 300 mRem/Yr.
