The Production of Radioactive Xenon for Animal Exposures
Large amounts of Xe133 were needed to study the biological effects resulting from inhalation of radioactive gases. This paper deals with the problems of collecting and concentrating Xe133 and with the problems of separating it from the uranium matrix after fission

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.

Radiotoxicity of Injected Sr89 for Rats, Mice, and Rabbits. Part III. Lethal Action and Clinical Changes
The LD 50 in 30 days was found to be between 7 and 8 uc/g of Sr89-Sr90 when administered intraperitoneally to mice; for rats it was slightly less than 5 uc/g; for rabbits it was also slighly less tha 5 uc/g

The Effect of Plutonium on Tissue Metabolism of Rats
When plutonium is introduced into the body either by injection or by intratracheal instillation, there are, in addition to the usual signs of damage to the lymphoid tissues, definite alterations in the metabolism of tissues.

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

The Interference of Nickel in the Reduction of Uranium Solutions in the Jones Reduction: a Study of the Effects of Nickel, Cobalt, Manganese, Zinc, Calcium, Magnesium, Aluminum and Sodium Ions upon the Reduction
Nickel interferes seriously with the reduction of uranyl solutions in the Jones reductor. Nickel ion, if added after reduction of a uranium solution has no harmful effect upon the aeration and the titration with standard ceric sulfate solution.
