humanssuffering from leukemia and allied diseases. December: (p. 3, tracer studies) "To date, it appears that satisfactory preparations of yttrium, zirconium,cerium, strontium, barium, and plutonium can be made for intravenoususe in man.” monthly reports NDP 48A from July 43 to December 46 by JGH were declassified on 2/10/61. Among papers found in the folder titled "Manhattan Engineer District--Health Division Group 1943-1944): a letter from Stone to Hamilton, dated June 1, 1943: "the idea is something like this--if you sished to raid a place and make everybody nauseated, vomiting and incapacitated within a period of 24 hours, how muchradioactive material in either gammar-ray or beta-ray emitter type is needed?” Carton 2 folder 30--Dec 46: Report of work during month of Dec., 1946, includes description of Total Body Irradiation with X-rays and P 2, by B.V.A. Low-Beer. He hadthree patients started under a program of X-ray irradiation and followed with regard to bloodcount. Radioiodine studies were done under the leadership of Earl Miller; 12 people were given radioiodine in December to track the amountof iodine in the body. In January 10 resume of curent work with radioactive materials in the Donner Lab of Medical Physics,it is mentioned that the short-lived isotopes of zirconium andyttrium can be made which would be useful immediately in clinical studies of circulation in man. Carton 25, folder 10: Jan 9, 46: Stone asked Hamilton to help the University of Chicago again; Hamilton would be getting instructions from either Miller or Low-Beer. Lawrence had already agreed to help. It is not stated what the purpose of the help would be. Carton 31 folder 3: E.O. Lawrence's Oct. 1, 1947 research program of the Radiation Lab. at UC for the coming four years report, p. 11, describes the biological and medical research program: Metabolism offission products (under leadership of J.G. Hamilton)-projected planscall for continuing tracer studies of fission products and extend these to include rare earths; they will be studied in the body [but whose bodyis not specified]. Medical effects of radiation (under Stone)--the effects of radiation from internal and external sources will be studied; the program was started in 1942 as a study ofthe effects of total body X-ray treatments on the blood of patients and was expanded to include the effects originating internally from P32 and 1131, Biological effects of radiation (under J.H. Lawrence)--the continuing study of the biological effects of radiation, with comparative studies of other formsofirradiation of tissue in situ for both research and health protection; it includes selective tissue irradiation with phosphorus, yttrium, zirconium, lanthanum, and uranium. Appendix I shows a summary of research and development work in progress or planned. p. 21 is copied below: Lawrence Berkeley Laboratory Archives and Records Office Human Radiation Experiments Search and Retrieval Project Anna Berge Research Notes Electronic DocumentTitle: Bancroft/EOL April 4, 1994 7
