nuclear species were either lacking or present in very low concentration.
A aotion 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 90¢,. 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 9055 intake and materially reduces the
137¢5 intake as well.
Removal also of land crab meat from the diet seems
advisable, and such restrictions bring the 905+ intake down to 115 pCi/day
or 270 pCi/g Ca.
The corresponding M3766 intake is 2290 pCi/day.
Doses to the whole body from
3les and Fe were calculated assuming that
Lhe reduction of radioactivity in the diet occurs only from radioactive decay.
Doses to bone from 90¢,. 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 unternal and external
radiation over 5-,
in 1970 are indicated in Table 4.
30- and 70-year intervals
The doses acceptable for individuals and
for a suitable sample of the population during the same time
