“…Data on the distribution of a3gPu in humans comes from 4 autopsy sources: Los Alamos,(?Jl) Rocky Flats, (22) Hanford,(s) and non-occupational exposures. First, they suggest that the risk from a presently "permissible" body burden of 239Pu could possibly be greater than has been believed previously.…”

The permissible body burden of 239Pu in radiation workers is 0.04 pCi. A literature survey indicates that the Pu reaching the circulatory system from occupational exposure may redeposit roughly half in bone and half in liver. For a constant 0.02 pCi 239Pu in bone and 0.02 pCi 239Pu in liver, the 50-yr doses to man are 14 and 57 rads, averaged over these respective organs. Probabilities of radiation-induced tumors from these doses are estimated as follows:
