[Combined effect of 239Pu and external gamma radiation on pregnant and lactating rats].
Exposure of pregnant and lactating rats to external gamma-radiation (12.9-103.2 mC/kg) caused 239Pu redistribution within their bodies. The increase in the transfer of 239Pu to the progeny was maximum after gamma-irradiation of pregnant rats with the dose of 25.8 mC/kg. The decrease in the intake of 239Pu by the progeny was maximum after gamma-irradiation of lactating rats with the dose of 12.9 mC/kg. With the combined effect of gamma- and alpha-radiation gamma-radiation was shown to play the major role in the embryos death.
