The resultant daily intakes are shown in Table 3, and are compared with the daily intakes which will lead to acceptable body burdens Ley individuals und a suitable sample of the population. Special procedures ‘wi.ich will greatly reduce the 905, content of the fruit can be undertaken vLanting when edible pandanus is re-introduced to the Atoll. »vait would be available about five years after planting. Edible The fact that vdaible pandanus fruit will not be available for several yearg removes what mishet have been the major source of 90g, intake and materially reduces the 137 eg intake as wcll. Removal also of land crab meat from the diet seem: udvisable, and such restrictions bring the 9057 intake down to 115 pCi/day or 2/0 pCi/g Ca. The corresponding 13765 intake is 2290 pCi/day. Doses to the whole body from 137 Cs and >°Fe were calculated assuming chat the reduction of radioactivity in the diet occurs only from radioactive d cuy Yovs to bone from 90, were also computed. ax Lubolism, purpuses. adults and children were Bucause of marked differences in considered scparately for internal dose The total doses to whole body and to bone for children and aduits Lrom internal and external radiation over 5-, 30- and 70-year intervals siaicving in 1970 are indicated in Table 4.
