The concentrations of Sr/sup 90/ and stable strontium were measured in the bone ash from pregnant sheep ewes and their fetuses. The fetuses weighed from 125 g (Sr 0) and 110 g (stable strontium) to 2650 g. In the ewes the average concentration of Sr/sup 90/ was 40.4 (s.d. 6.4) pc/g calcium in the metatarsal diaphyses and 38.4 (s.d. 3.9) pc/g calcium in the vertebrae. The average concentration of stable strontium was 321 (s.d. 37) ppm in the metatarsal diaphyses and 324 (s.d. 26) ppm in the vertebrae. No significant difference between the two bones in the concentrations of either Sr/sup 90/ or stable strontium was found. In the fetuses the average concentrations of Sr/sup 90/ and stable strontium in the ash from the ossified parts of the long bone diaphyses was 16.2 (s.d. 2.5) pc/g calcium and 152 (s.d. 27) ppm respectively. The average ratio between the strontium concentrations in the long bones of each fetus and the metatarsal bones of its mother was 0.41 (s.d. 0.06) for Sr/sup 90/ and 0.48 (s.d. 0.08) for stable strontium. The strontium concentrations in the fetal and maternal bone ash, and the ratio between these concentrations, were essentially independent of fetal weight and sacrifice date. (auth)
