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%).
在对大鼠的实验中发现，单次注射137Cs并对睾丸进行局部X射线照射，在吸收剂量相等的情况下，通过显性致死和半致死频率、相互易位、单价体和染色体片段来检测时，配子中的突变产量是不同的。与睾丸局部照射相比，全身照射在诱导遗传损伤方面效率更高，并且在吸收剂量形成停止后的很长一段时间内，损伤数量有统计学意义的增加，这表明全身照射的间接效应导致了遗传结构的损伤，并允许大致估计其贡献（高达50%）。
