ICh. reference lists spleen rather than whole body as the critical
creiin. Gustafson probably used whole body so that the doses would be
additiv:.
toe splean, the following is obtained:
AEC Manual Chapter 0524 which treats. the case for the critical organ
gives an uncontrolled area MPC for

The value for the general public would be

Assuming an intake on a per day basis we have:
8 x Lom} uci/ml x 1,200 M/s, = +3 nCi/day

3x 10° pCi/day
Thus, even for the spleen, the dietary value of 59,500 pci/day in
Table VI' is only about 1/5 of the MPC.
Meg dose (adults)
At eqrt librium the initial body burden would be:
By = 2,290 pCi/day x 1.44 x 100 days x 1

Initial dose rate would be:
