-~1}9~ In conclusion, we note that our proposal for limiting the exposure of younger workers while allowing a 4 “oh Nigher exposure to older workers is not now, It is, in fact, similar to a 1955 recomnendation of the NAS Committee on the Genetic Effects of Atomic Radiation in the BEAR Report: F) That every effort be made to assign to tasks involving higher ra- diation exposures individuals who, for age or other reasons, are unlikely tnere- after to have additional offspring. Acai lit is recognized that such a procadure will introduce complications and @difficultie but this committee is canvinced that should begin to modify its procedures to meet undiminisnecé while, inevitable new conditions.21/ at the same time, the cancer inducing potential of radiation is now recognized to be much greater and the nish radiosensitivity of the developing embryo and fetus is also now recognized. 0 th xDBn ingc nuclear industry, In the voresence of an the time to imelement this recommendation Ras arrived.
