Southern California Edison Company P.O. BOX 351 LOS ANGELES, CALIFORNIA 90053 January 19, 1971 Dr. Josh Lederberg Department of Genetics Stanford University School of Medicine Palo Alto, California 94305 Dear Dr. Lederberg: I have been trying to familiarize myself with the current discussions on radiation standards and find myself somewhat handicapped since I am not a health physicist. I understand that you have made a cost analysis of the genetic effects of radiation which you sent to the Pennsylvania State Senate Select Committee in mid-1970. I would appreciate receiving a copy of this study, together with any literature citations of similar studies. In particular, I would be interested in any comments you may have on the 32,000 deaths per year calculated by Drs. Gofman and Tamplin. Thank you very much for the information. Very truly yours, . / - / E. N. Cramer Engineer for Advanced Energy Systems
