title: [Mutagenic effect of different types of irradiation on the sex cells of male mice. IX. Duration of preservation of radiation-induced reciprocal translocations during the course of the reproductive period].
abstract: The rate of induction of reciprocal translocations by gamma-irradiation of mouse spermatogonia was studied by cytological examination of descendent spermatocytes. The CBA mice were given a total single acute dose of 300 r or 3 times per 300 r with 7 and 28 days intervals. The irradiated mice were killed within 3,7 and 12 month after the irradiation. The frequency of translocations in 3 and 7 month after the treatment was the same. A 25% decrease in the yield of reciprocal translocations was observed in 12 months after the irradiation. It suggests that the genetic risk from ionizing radiation remains high a year after the irradiation.
