The highest estimates for cancer risk result from using

The lowest estimates result from
the linear-quadratic absolute risk model and are slightly less than those
for the absolute model in Table 2.
Thus, as far as estimates of cancer
risk are cone ‘n~~ed,those obtained using risk coefficients from BEIR-I

are in the same general
range as those obtained using risk coefficients
from BEIR-111.
Risk estimates for birth defects obtained using the risk factor from
BE~R-I gives
values about three times those obtained using the upper
value of the range of risk factors given in BEIR-111.

If BEIR-111
factors for bith defects represent a more enlightened assessment
of this potential consequence of radiation exposure than the factor
taken from BEIR-I f~r overall health defects, then the estimates
in the Bikini book may be conservative by a factor of three.
