nuclear species were 2ither lacking or present in very low concentration. A notion of the possibie daily intake of the above three radionuclides may -be obtained by taking che 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 @ suitable sample of the population. Special procedures which will greatly reduce the 905, 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 after 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 1375 intake as well. advisable, Removal also of land crab meat from the diet seems and such restrictions bring the 905, intake down co 115 pCi/day or 270 pCi/g Ca. The corresponding 1370. intake is 2290 pCi/day. Doses to the whole body from 137Es and °Fe were calculated assuining that the reduction of radioactivity in the diet occurs only from radioactive decay. Doses to bone metabolism, purposes. from 90 Sr were also computed. . . Because of marked differences in adults and children were considered separately for internal The total doses to whole body and to bone dose for children and adults from internal and external radiation over 5-, 30- and 70-year intervals starting in 1970 are indicated in Table 4. The doses acceptable for individuals and For a suitable sample of the population during the same time intervals are also indicated. EE 95515
