Abstract
P32 or Sr89 was administered to rats by stomach tube, and the intestinal absorption was determined by measurements of the radioactivity of the intact tail for several hours. External tail radioactivity was proportional to body content of isotope during the initial absorption. Absorption of radiophosphorus was rapid, the highest rate of absorption being found at 30 minutes. Radiostrontium absorption was usually slower.
