RESUMO
In order to examine the effects of radiation, chemicals, and social factors on the incidence of different diseases in the population living in the vicinity of atomic industry facilities, the site of the Production Association 'Mayak' has been selected for detailed analyses. Diseases under study were morbidity among newborns including congenital anomalies, diseases of respiratory organs, and cancer. Using a regression model, no statistically significant correlation was found between incidence and radiation exposure.

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.
