In the course of studies on the biological behavior of radiofission products in pregnant animals, the excretion of radiostrontium with the mother's milk and the resulting accumulation of Sr/sup 90/ in the new-born during the lactation period were investigated. On the l7th day of gestation, the albino rats used in the study were injected with 20 mu c solution. The newborn mice were exchanged with those from controls, so that three groups of rats were obtained. The first group were inactive newborn with active mother, the second active newborn with inactive mothers, and the third active newborn with active mothers. On the 5th, 10th, 15th, and 20th day after birth, animals were sacrificed and the amount of strontium determined as a percentage of the strontium injected into the mother. The results show that in the young animals which received Sr/sup 90/ in the mother's milk but which were born of inactive mothers, the Sr/sup 90/ content increased. In the new-born which received radiostrontium during the placental period but were fed with Sr-free milk, the Sr/ sup 90/ content remained constant for the first 15 days, but decreased when the animals received standard food. The young animals of the third group receive radiostrontium with the mother's milk, and the strontium concentration in the animals increase. The sacrifice of the mothers on the 20th day after birth showed that the strontium content was 0.35% of the injected dose. (J.S.R.)
