Excretion of Radium from the Mouse

Abstract

Excretion of Ra following intraperit. injn. was studied in 3 groups of strain C3H mice. Two groups were given British anti-lewisite (BAL) as a possible means of increasing the elimination rate. An avg. of 19% of the injected Ra remained in the mouse at death 100 to 240 days after injn. The avg. elimination rate was 0.01% per day and was unaffected by BAL.
