Population dose guidelines used by the Task Group include annual dose
rates as well as 30 year integrals for genetic doses.

with age as these would influence dose to the fetus, the newborn, to

Estimates are developed both for persons who
are adults when they return and for children born after return of their
parents to the Atoll.

Conservative values have been selected for variables in models for
assessment of expected doses.
Though conservative, the estimates are not
considered ultra conservative and do not constitute the theoretical
maximum credible or worst case exposure.
These conservative estimates of
expected maximum annual exposure presented in Appendix IV are considered by
the Task Group to be applicable to individuals in the Enewetak population,
There will be few persons within this population at any one time who are fetus,
newborn, or infants, believed to be the most sensitive members.
Therefore,
the predicted exposures are judged suitable for comparison with FRC exposure
guides for individuals within an exposed population.
