[Radiation effects in ontogenesis of the progeny of one or both irradiated parents].

The purpose of the investigation is the study and comparative analysis of radiation effects observed in antenatal and early postnatal ontogenesis of first generation progeny when one or both parents have been irradiated in doses 2, 3, 4 Gy. It was shown that the effects for the posterity of both exposed parents were attributed mainly to a female if mature oocytes were exposed to radiation, or to a male if maturing oocytes were exposed. If both parents have been irradiated at the spermatid, spermatozoid or mature oocyte stages and got 4 Gy aggravated effects in progeny are observed. It is may be related to synergistic mechanism of realization of this phenomenon.
