(UNCLASSIFIED) An extensive stady of the affects of ionising radiation on parabiotic rats has been completed under an AEC project at the New England Deaconess Cancer Research Institute in Boston. Experiments were performed by joining together two animals of the same sex and of comparable age and weight. A fairly complete interchange of circulating blood was thus provided between the animals, and varying dosages of ionizing radiation were given to only one meanber of the joined pair. The results of the experiments clearly demonstrate that there was no pathologic evidence of injury produced in the nonirradiated animal such as might be mediated by aireulating substances, and that some protection was provided by the non-irradiated animal via the blood stream to the irradiated one of the pair. Study of sub-Human Primates Aireraft, the Division met at Oak Aidge with Uak ridge we “embers of Laboratory and U.3. Air Pores (Sehool of Aviation Medicine Primate Laboratory at dustin, Texas) personnel to «discuss a cooperative study on the effects of various levels of radiation to occupants of nuclear aircraft. The need for 4 long-term experiment sith sub-luman primates was recognized. However, in view of the magnitude of the project, 4t was agreed that some preliminary data were required to oope with the problems of such an experiment and to eliminate the necessity of transperting animals several times between Austin and Gak Ridge. It was planned therefore to initiate a pilot project at Jak Ridge aa s0on a8 possible using the Dulk Shielding Facility. cata ob- tained from the study would be useful in guiding ONL research on . wa oh ; vt day eed ¥ DOSARCHIVES
