[Late sequelae of gamma irradiation of rat ovaries during embryonic development].

From abnormalities in the first pregnancy, antenatal and postnatal development of the Wistar rat offspring subjected to a single whole-body gamma irradiation (0.5-1.5 Gy) during embryogenesis, it was inferred that ovaries were most radiosensitive on days 10-16 of the antenatal ontogeny with regard to the remote effects of irradiation.
