Abstract : A method was developed, allowing the appraisal of the reaction of different forms of animals to the effect of radiation in small doses under conditions of their constant containment. The method can also be used for the characteristic of individual sensitivity of animals to radiation. It was shown that animals react to very small doses of radiation on the order of 1-2 R during irradiation of the region of the head and stomach and of 0.001 R and 0.05 R during general irradiation. The ability of different forms of animals (mice, rats, guinea pigs and apes) to determine the location of a source of radiation and to avoid the drinking bowl, located in the area of the source of gamma radiation was revealed. The threshold values of dose rates, to which the animals reacted during total irradiation were determined. For guinea pigs the threshold dose rate was equal to 0.0017 R/s; for mice - 0.0023 R/s, and for rats - 0.0127 R/s. A comparison of the threshold dose rates of radiation, to which the different species of animals reacted under our experimental conditions permits arranging them according to sensitivity in the following way: the most sensitive were the guinea pigs, then the mice and then the least sensitive the rats.
