A comparative study of the incidence of genetic damages induced in mouse male germ cells by a single injection of 137Cs and external gamma-irradiation shows that the incidence of dominant lethal mutations in the postmeiotic cells is similar with both radiation types. The frequency of reciprocal translocations in stem cell spermatogonia was considerably lower with 137Cs than with external gamma-irradiation which might be attributed to the prolonged effect of the radionuclide.
一项关于单次注射137铯和外部伽马射线照射对小鼠雄性生殖细胞诱导的遗传损伤发生率的比较研究表明，两种辐射类型在减数分裂后细胞中的显性致死突变发生率相似。与外部伽马射线照射相比，137铯在精原干细胞中的相互易位频率要低得多，这可能归因于放射性核素的长期效应。
