Criteria Against Which Survey Findings and Alternative Measures
Will Be Evaluated
The Task Group approached the question of radiation dose criteria
from two directions. First, FRC, ICRP, and NCRP recommendations
reviewed above were judged as to applicability in this situation.
Second, a risk approach was reviewed using information from
ICRP, UNSCEAR, and the National Academy of Science BEIR
Committee. The results of this latter effort are summarized
in Part F which foliows.
The radiological survey of Enewetak Atoll provides a comprehensive
data base needed to derive recommendations relative to the
radiologically safe return of the Enewetak people. These recommenda-
tions are to be based on an evaluation of the significance of all
radioactivity on the Atoll in terms of the total exposure to be expected in the returning population, and on consideration of those
reasonable actions and constraints which, where made, will result
in minimum exposures.
The guidelines used in deriving these recommendations can be
summarized as two interdependent considerations:
1. Expected exposures should be minimized and should fallina
range consistent with guidance put forward by the Federal
Radiation Council (FRC).
