Return to Bikini.
The ratio of total internal committed effective dose
equivalent to external dose equivalent was plotted by us versus time of return
relative to the BRAVO detonation.
It is apparent to us that the ratio
increases with increasing time post return.
In general, the ratio at Bikini
Island would be about 2.5 if return in 2020 is hypothesized. From 2020 to
2050, we estimate an external whole body dose equivalent if 0.015 Sv (1.5
rem). The total estimate of internal plus external dose equivalent would be
about 0.05 Sv (5 rem) for this 30 year period. Therefore, an unrestricted
rehabitation of Bikini Atoll might begin in 2020 if their eqygroment is not
cleaned-up.
equivalent.
This dose equivalent estimate is exclusive of
