[Cytogenetic effect of 238Pu alpha radiation on the germ cells of male mice].
A study was made of the yield of reciprocal translocations in stem spermatogonia of mice exposed to alpha-radiation (238Pu) and whole-body acute and chronic gamma-radiation within a wide range of doses and dose-rates. The frequency of reciprocal translocations induced by a single intraperitoneal administration of plutonium nitrate was relatively low and independent of the dose 1.5-18 months after the effect. The yield of the reciprocal translocations induced by chronic effect of gamma-radiation was appreciably lower than that observed after acute irradiation with the same dose and grew linearly with dose. The RBE of alpha-radiation was 10-20 with respect to chronic effect of gamma-radiation.
