The Effect of Age on the Radiosensitivity of Mice

Description: Abstract: Mice of different ages ranging from 1.5 to 12 months have been exposed to gamma rays in an effort to determine the change in radiosensitivity with age. The dose necessary to cause 50% killing was determined for each age group and sex. No change in sensitivity with age was observed with either sex, although the experimental error in the case of the males was quite large. The females were found to be more resistant than the males.

Some Studies of the Reactions of Uranium Oxides with Hydrogen, Oxygen and Water

Description: Abstract: The purpose of this research was to obtain data that would be useful in predicting changes that might be expected to occur in the oxidation state and degree of hydration of powdered uranium oxides maintained for long periods of time at temperatures between 30 and 300 degrees C. in the presence of excess water, hydrogen, oxygen and possibly hydrogen peroxide. The reaction of hydrogen and oxygen with water slurries of U3O8 were studied at 100-300 degree C.

Observations on the Preparation of the Tribromide and Triiodide of Uranium

Description: 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

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

Description: 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.
