nuclear species were either 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 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
'37¢s5 intake as well.
Removal also of land crab meat from the diet scems
advisable, and such restrictions bring the 90sy intake down to 115 pCi/day
ov 270 pCi/g Ca.
The corresponding 137. intake is 2250 pCi/day.
Noses to the whole body from 137e, 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 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
