Abstract : The adaptive protective reactions of an organism to the changes evoked by ionizing radiation have been insufficiently studied. This work is an attempt to examine certain of them. It was shown that with daily whole-body irradiation of rabbits by x-rays in doses of 0.1 and 0.05 r the changes in the time of the flexor reflex of the lower leg that follow a single exposure disappear quickly. Each subsequent exposure does not cause a change in the time of the reflex. The obtained results were evaluated as the organism's becoming more and more accustomed to a constantly acting agent. The relatively few data summarized in this article indicate that adaptive mechanisms arise sooner under repeated exposures than under the first irradiation.
