[Effect of Sr-90 on the reproductive function of rats after chronic exposure]

In experiments on white rats following long-term 90Sr exposure within a wide dose-range the effect of 90Sr on reproductive function of animals has been observed both over the entire reproductive period and in seven subsequent generations. It has been established that the ovule fertilization and the intrauterine fetus development did not differ from these values in control animals. However in some cases the loss of progeny was significant following the isolation of animals from parents. The physical development of rats in suckling period and sex proportion did not differ from the control progeny.
