The reported experimental data are concerned with the frequency of turmor incidence, pecuilarities of their localization and morphological structure in rats in per oral administration of Sr-90, Cs-137, 1-131 and external irradiation under conditions of a continuous experiment. There was shown a definite correlation between the type of the radiation effect and total absorbed dose and tumor development. Tumor localization was mainly conditioned by the character of radionuclide distribution in the organism. The frequency of tumor incidence was dependent on the radiation dose. However, in proportional doses the blastomogenic efficacy of Sr-90 was found to be higher than that of Cs-137, 1- 131 and external irradiation. A minimum osteosarcomogenic dose in Sr-90 injection was approximately 1000 rad. (auth)
