title: [A comparative evaluation of the genetic effects of uniform internal (137Cs) and local x-ray (testes) irradiation of rats].
abstract: In experiments with rats it was shown that with equal absorbed doses after single injection of 137Cs and local X-irradiation of testes the mutation yield in gametes was different when tested by the frequency of dominant lethals and half-lethals, reciprocal translocations, univalents, and chromosome fragments. A higher efficiency of whole-body irradiation as compared to local exposure of testes, with respect to genetic damages induction, and the statistically significant increase in the number of the damages during a long period of time after cessation of the absorbed dose formation indicated that indirect effects of whole-body irradiation contributed to the injury to hereditary structures and permitted to estimate approximately their contribution (up to 50%).
