DOE ARCHIVES - 3 - nuclear species were cither lacking or present in very low concentration. A notion of the possible daily intake of the above three radionuclides may be obtained by taking the diet eaten by the Rongelapese as a guide, and using the observed concentrations of radioactivity in the same food items collected on Bikini. The resultant daily intakes are shown in Table 3, and are compared with the daily intakes which will lead to acceptable body burdens for individuals and a suitable sample of the population. Special procedures which will greatly reduce the 906). content of the fruit can be undertaken at planting when edible pandanus is re-introduced to the Atoll. fruit would be available about five years aiter planting. Edible The fact that edible pandanus fruit will not be available for several years removes what might have been the major source of 905, intake and materially reduces the '37¢5 intake as well. Removal also of land crab meat from the diet seems advisable, and such restrictions bring the °%sr intake down to 115 pci/day or 270 pCi/g Ca. The corresponding M370. intake is 2290 pCi/day. Doses to the whole body from 137 Cs and >°Fe were calculated assuming that the reduction of radioactivity in the diet oceurs only from radioactive decay. Doses to bone from 906) were also computed. Because of marked differences in metabolism, adults and children were considered separately for internal dose purposes. The total doses to whole body and to bone for children and adults from internal and external radiation over 5-, in 1970 are indicated in Table 4. 30- and 70-year intervals starting The doses acceptable for individuals and for a suitable sample of the population during the same time intervals are also indicated.
