msg RADIATION STANDARDS, INCLUDING FALLOUT 349 i i Dr. Guass. My statement is that if they received upward of 200 roentgens, there might be a sterilizing effect upon the female or some of the females, because I believe there is inadequate knowledge of just what the sterilizing dose for the human female is. In the case of the Hiroshima females who were irradiated and who later reproduced, I do not know whether the dosage measurements are sufliciently accurate to throw light on this question or not. It would be worth looking into. Representative Price. Mr. Hosmer. Representative Hosmer. No questions. I was unable to listen to all of the testimony. Representative Price. Does the staff have any questions? If not, thank you very much, Dr. Glass, for a very fine presentation, In fact, all of the papers this afternoon were excellent and valuable to the committee.

RaMEY, EHeecutive Director, Joint Committee on Atomic Energy, U.S. Senate Post Ofice, Washington, D.C. Desk Mr. RaMey: I have just read through Dr. Bentley Glass’s testimony given at the recent hearings of your committee. I believe that he has covered the recent advances in genetic effects of radiation since the last hearings extremely well and that there is nothing essential that I could add. For this reason I have not prepared a statement for the record. I hope this is satisfactory. Let me take this opportunity to express ‘to the members of the Joint Committee and its staff my genuine appreciation for the great public service that they have accomplished through these hearings. I am very honored to have participated in the 1957 and 1959 hearings and to be invited to this. With best personal regards. Sincerely, JAMES F. Crow. te DEPARTMENT OF MEDICAL GENETICS, Madison, Wis., June 27, 1962, - THE UNIVERSITY OF WISCONSIN,
