Fifteen-day balance trials were done with 14 healthy infants of about 34 days of age for Sr/sup 90/, stable strontium, calcium, and phosphorus. Average retentions were: 28% Sr/sup 90/; -71% Sr. 31% Ca; 30% P. The loss of stable strontium from the body as compared to the retention of the other substances most probably is accounted for by the decreased intake of stable strontium that occurred at the start of the observational feeding period. Dietary Sr/sup 90/ and calcium were added to the bodies of the infants in a ratio that was about 0.9 of the Sr/sup 90/ to calcium ratio existing in the diet. This corresponds approximately to an OR/sub body/diet/ of 0.9 which contrasts with the accepted value of 0.25 for adults and indicates a lesser capability of the very young to discriminate against strontium in favor of calcium.
