[The yield of genetic disorders in mice exposed to the action of fractionated ionizing radiation in embryogenesis].
In studying the occurrence of genetic lesions in mice subjected to daily long-term gamma-irradiation at different periods of the antenatal development, increased preimplantation losses were revealed in offspring of females irradiated with a cumulative dose of 1.25-3.5 Gy. In male offspring the death rate did not significantly vary from the control, but the incidence of abnormal spermatozoa heads and reciprocal translocations in spermatocytes was increased.
