The resultant daily intakes ‘are shown in Table 3, and are comparcd with the daily intakes which will lead to acceptable body burdens tov individuals and a suitable sample of the population. Special procedures w..ich weal greatly reduce the 90¢, content of the fruit can be undertaken at planting when edible pandanus is re-introduced to the Atoll. suit would be available about five years after planting. Edible The fact that edible pandanus fruit will not be available for several years removes what Right have been the major source of 905, intake and materially reduces: the t57¢5 intake as well. Removal also of land crab meat from the diet seems advisable, and such restrictions bring the 90s; intake down to 115 pCi/day or 270 pCi/g Ca. The corresponding 1376. intake is 2290 pCi/day. Doses to the whole body from 137¢, and >°Fe were calculated assuming that the reduction of radioactivity in the diet occurs 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-, 30- and 70-year intervals starting in 1670 are indicated in Table 4.
