REPOSITORY Gonaf_ couecrion Zé 3 President Robert Gordon Sproul University of California BOX No. 67 Berkeley 4, California FOLDER $00 ° Y- 5/ (NN? - 726 -97—o0 Qe. 2. Dear President Sprouls . -_ (6- ¥-47) I wish to endorse the request of the Secretary of the Navy that Professors R. L. Overstreet and Louls Jacobson participate in the Bikini resurvey being undertaken by the Navy Department during the coming summer. As you know, the possible biological effects of radioactivity from nuclear fission products are of great concern to the Atomic nergy Commission, not only as they directly involve problems of human physiology but also in connection with possible effects on agriculture and fisheries. The enormous amounts of fission products deposited on the reefs and in the waters of Bikini Atoll as a result of the underwater bust last summer, and the very large accumulations of these materials by plents and animals, make this area an important and unigue field experi- ment station for radiobiological problems of plant nutrition and soil chemistry. Because of their special experience and mature com petence, Professors Overstreet and Jacobson are widely recog- nized as leaders in these fields. It is believed that their participation in the expedition will insure the successful accomplishment of its most important objectives and that without them great difficulty may be experienced in attaining these objectives. I therefore strongly urge that you authorize the diversion of the time and energies of these scientists and whatever assistants they may desire from their present in portant work so that they may teke part in the expedition. Sincerely yours, hesDEPART pec MENT OF ENERGY DECLASSIFICATION REVIEW SINGLE REVIEW eee BY: US ; PPLE OeOe REVIEWER (nox EB $me DATE: ATE DETERMINATION {CIRCLE NUMBER(S)} 1.
