calculated for mineral bone. . These mineral bone doses are compared to
the federal guide of 3 rem/year for a member of the population.
The
doses in this report, and in the AEC Task Group Report (32) for Enewetak
Atoll, were calculated for bone marrow and are compared to the federal
guide of 0.5 rem/year for a member of the population.
The bone doses
_ listed for Enewetak Atoll in the Enewetak Radiological Survey Report (1)
have been converted to bone marrow doses and included in Table 33 to
allow comparison with doses from Bikini Atoll.
The federal guides for whole body and bone marrow are listed in
the last column of Table 33 for comparison with the predicted doses for
each of the major living patterns at the two atolls. - Doses predicted
_for Bikini Island exceed the guidelines while the Engebi Island living
pattern is very marginal.
Eneu Island and the southern half of Enewetak
Atoll lead to predicted doses below the federal guides.
The accepted methodology for evaluating living patterns on Enewetak
Atoll was to reduce the federal guides by 50% to compensate for the
fact that "the doses cannot be precisely predicted" (32).
If a similar
method is adopted for Bikini Atoll then the reference guide would be
0.25 rem/year for whole body and bone marrow, or 7.5 rem over 30 years.
In this case Bikini Island and Engebi Island definitely exceed the guides
and Eneu Island is marginal.
course no problem.
The southern half of Enewetak Atoll is of
In fact, the predicted doses for the southern half
of Enewetak Atoll] are less than those expected from natural background
radiation exposure in the United States (see Table 33).
In final analysis it would appear that for living patterns using
