Retention of /sup 226/Ra was substantially lower in mature beagles injected at 5 years of age compared to corresponding values for young adult beagles injected at 17 months of age. As with young adults, the percentage retention in mature dogs given about 10 ..mu..Ci/kg exceeded that in mature dogs given 4 ..mu..Ci/kg or less. Measured /sup 222/Rn//sup 226/Ra ratios in bone were similar in mature and young adults. Roughly 66% of the injected radium was excreted by mature dogs during the first 3 weeks, about two-thirds of the total excretion appearing in the feces. Distribution of /sup 226/Ra within the skeleton was similar in mature and young adult beagles.
