Title: LOCALIZATION BY AUTORADIOGRAPHY AT -195 C. OF RADIOACTIVE AREAS IN RATS EXPOSED TO A HIGH FLUX OF THERMAL NEUTRONS: IMPORTANCE OF PHOSPHORUS-32 IN CONSECUTIVE INTERNAL IRRADIATION

Abstract

Work was carried out to localize, by autoradiography at - 195 deg C, the organs of areas of the body of a rat capable of becoming the seat of radioactivity induced by exposure to a high flux of thermal neutrons. Rats weighing 25 g were placed alive, in pairs, in plastic irradiation cartridges and exposed to 5 min irradiation. After ascertaining that they had been killed by the flux of neutrons, the rats were immediately frozen in liquid nitrogen. Autoradiographs were made at times of 1, 2, 12, and 24 hrs, flux of thermal neutrons involved, by the radioactivity induced in the body, a general irradiation of relatively short duration by gamma rays of Na/sup 24/ and K/sup 42/ and to much longer irradiation essentially localized in the skeleton by the beta rays of P/sup 32/ and Ca/sup 45/. The bone marrow, therefore, must be considered as a critical organ with regard to irradiation by thermal neutrons. (M.C.G.)
