inélargest individual 5U year doses tor persons born atter return
occur under the Enjebi living pattern for children born eight years
after the return and existing under famine conditions.
Under the
normal diet pattern the 30 year dose is 4.0 rem; in famine it is
7.5 rem (Table 44 of Dose Assessment).
Again assuming famine
conditions will exist 25% of the time, we have an upper credible
30 year dose of
((4.0x0.75)+(7.5x0. 25) J= 4.9 rem,
per year on the average.
or about 163 mrem
It is notable that only the first case, that of adult females for
the Enjebi/Northern Island living pattern, exceeds the FRC general
population guides of 170 mrem per year of 5 rem per 30 years for
the general U.S. population.
The excess estimated dose is
furthermore very small; 0.6 rem for 30 years, and 13 mrem per year
average.
The estimated doses are all far below allowances for
occupational exposure and below the recommended Action Guides
applicable for the general U.S. population.
Furthermore, the
excesses are more than made up for by the lower average natural
background radiation exposure encountered in the Marshall Islands
than in the continental United States.
