[Mammary gland tumors of rats born to parents irradiated before conception].
The effect of exposure of male or female rats to radiation 5 days before conception on the frequency of development of mammary tumors in their progeny is described. It was shown that mammary tumor incidence and the rate of their development increase in a population of female rats - descendants of one of parents exposed. Irradiation of would-be mothers produced a stronger blastogenic reaction in their progeny than that of fathers.
