Memo from To: JOSHUA LEDERBERG E.N.Cramer JAN 25 1971 Radiation Standards It is hard ta prove that Gofman is wrong in his estimate of cancer yield; but he does cascade a number of implausible assumptions. I read he is now taking a different tack -- that a single case of radiation-induced cancer would be unjus- tifiable murder; which shifts the argument to quite another plane. The National Academy of Sciences is making a comprehensive formal study of radiation effects, and its report should be a great help in clearing up the controversy. The drafts you asked for are enclosed; I hope I am still moving towards a clearer definition of the issue, and will be preparing a more definitive paper for the Bulletin of Atomic Scientists. There is very little else on cost-benefit ana- ysis. You may want to read the reports of the the UN Scientific Committee on the Effects of Atomic Radiation, which are the principal guide- posts in the field. & "Environmental Effects of producing electric power", the hearings of the Joint Gong. Committee on Atomic Energy, 1970. Sincerely, PROFESSOR JOSHUA LEDERBERG Department of Genetics School of Medicine Stanford University Stanford, California 94305
