STRONTIUM-90 PLASMA LEVELS AND EXCRETIONS IN YOUNG ADULTS ON A LOW CALCIUM DIET
Strontium-90 plasma levels and excretions were studied in young adults fed on a constant diet of 1.1 g of Ca and 13.4 mu mu c Sr/sup 90/ a day. The average daily intake during 3 periods of 6 days each was 179 mg Ca and 3.3 mu mu c Sr/sup 90/. Calculations from food were made on the assumption that 20% of the dietary Sr/sup 90/ was absorbed. It was found that the average urinary excretion of Sr/sup 90/ calculated from the intake of Sr/sup 90/ was about 60% of that found, and the average Sr/sup 90/ plasma level calculated from food was 60% of the average levels calculated from the urine. This suggests that approximately 40% of the Sr/sup 90/ levels and urinary excretions during the studies was due to previous intake of Sr/sup 90/. The results were compared with previous data in which the Ca and Sr/sup 90/ were ingested with milk. (P.C.H.)
