-10- indicates that the risk of genetic damage is comparable to the leukcmia and cancer risk and, therefore, is also too high regardless of any special weighting that it deserves. Again, we strongly suggest that the upper Limit estimate of the genetic risk be used in this comparison. The BEIR Committee suggested caution in the use of these estimates and began its Discussion section by stating: A major concern of the Subccamittce is the possisle existence of a class of radiation-incuced genetic damage that has been left out of the estimates. By relying so heavily on exserimental data in the mouse we may have overlooked ‘important erfects that are not readily detected in mice, or the mouse nay not be a proper laboratory modei for the study of man.l9/ As if to reempnasive this, the Comnittee corcluéed this We renind all who may wse2 our estimates as a basis for solicy decisions that cthess estimates are an attempt to take i~ 4 0 radiation, and that there ma be intan¢gible a: whose cumvlati appreciable, a There iS reason to suggest that the BETR Committee should have implied an even nore cautious approach to their ftpid., Tid. 1 ™ iF" lit lQ/ v.57.
