Abstract
Studies were undertaken to determine the biologic distribution of 201Tl in man. The disappearance from the blood is extremely rapid and intracellular deposition is nearly immediate. The biologic half-time of Tl was measured by both the Brookhaven whole-body counter and the Donner whole-body scanner, with excellent agreement. The effective whole-body half-time of 201Tl is about 57 h. Concentration of activity was seen in the heart, kidneys, large bowel and thyroid. The whole-body radiation dose is 0.21 rads/mCi.
