[State of the progeny of the 1st generation conceived at different times after low-dose irradiation of female rats].
The relation between the antenatal and early postnatal ontogenesis of the progeny and the degree of maturity of oocytes at the time of the whole single gamma-irradiation with doses of 0.25, 0.5 and 1 Gy was studied on 473 first pregnant Wistar rats and 1402 rats of the first generation. Ontogenesis disorders ot the progeny of these females after irradiation of the matured oocytes were more marked than after irradiation of the maturing oocytes. The distinction was noticeable after a dose of 0.25 Gy.
