Radiotoxicity of Injected SR89 for Rats, Mice, and Rabbits. Part II. Metabolism and Organ Distribution

Mice, rats and rabbits excreted Sr89-Sr90 very rapidly following intraperitoneal or intravenous administration. The greatest part of the excretion took place during the first three days, and by 10-15 days virtually no more of the retained strontium was excreted.

Observations on the Preparation of the Tribromide and Triiodide of Uranium

Uranium Tribromide has been prepared both by the reduction of the tetrabromide with hydrogen at 600-700° C, and by direct union of uranium and bromine at about 580°C. An attempt to prepare the triiodide of uranium by the latter method was unsuccessful
