Oralloy Shape Factor Measurements

Description: Measurements have been at the Pajarito remote control laboratory to determine the effect of change of shape on system reactivity for oralloy cylinders. Systems tested include cylindrical configurations with various height-to-diameter ratios ranging from slabs to rods. Each system reactivity is referred to that of a sphere in the same tamper. Reactivity tests were made on bare (untamped) Oy configurations, as well as on systems In tuballoy tampers 1.12,1.87,and 8.0 thick. The amount of reactivit… more

The Reaction of Tritium and Stopcock Grease

Description: This investigation was begun as a result of a mass spectrometric measurement of two samples of tritium which had been stored for several months in Pyrex glass bulbs using stopcocks. The first of these was originally supposed to be of extremely high isotopic and chemical purity. What was observed at this time was 1.45 H had accumulated, and that tritiated methane, CT4, was also present to the extent of 0.18%. A consistent attempt had been made in this sample to protect the gas from contact with … more

Studies of the Metabolism of Certain Fission Products and Plutonium

Description: A short survey of some of the metabolic relationships of the elements, cerium, colurbium, plutonium, strontium, yttrium, and zirconium is presented. While the results of internally deposited radium have not been investigated in these experiments, they have been extensively studies by others. Because so much is known of its biological effects, it has been included in this historical survey.

The Photoproduction of Mesons from Hydrogen

Description: In an effort to gain information on the nature of the photon-meson and photon-nucleon interaction, a study of the artificial production of mesons by photons has been made at the Berkeley synchrotron. The major effort of this research was concentrated on a measurement of the energy and angular distribution of u+-mesons produced when the photons strike a target of liquid hydrogen. Detection of the mesons is accomplished electronically by the technique of delayed coincidence.

A Note on the Mechanism of the Formation of Alpha-Acylamino Ketones from Amino Acids

Description: The reaction of alanine-1-C14 and phenylalanine-1-C14 with acetic anhydride in the presence of pyridine has been studied and the carboxyl group of the amino acid has been shown to be the exclusive source of carbon dioxide involved.

Third Safety Considerations

Description: The present liquid third safety is considered undesirable for the piles at their present power levels. Any increase in power level and graphite temperature makes the need for an alternative third safety increasingly imperative. The use of the third safety is envisioned under conditions where the supply of cooling water to an operating pile is interrupted and concurrently the safety rods full to enter the pile because of slight shifting of the top shield or larger shifting of the winches, relati… more

Report of initial urinalyses on Bio-Assay personnel for the evaluation of benzol exposures

Description: In November, 1949, an industrial hygiene study was made of the operations conducted in the Bio-Assay Laboratory, 706 Building, 700 Area. This study was conducted by W.E. Gill and reported in HW-15654. One of the potential health hazards investigated was the use of benzol in laboratory procedures. An evaluation of this problem where the solvent was employed for cleaning glassware indicated that the solvent vapor was present in the workers` breathing zone in concentrations occasionally as high as… more

Forty-Niner, King Solomon Ridge, and West End Claims Near Clancy, Jefferson County, Montana

Description: Abstract: Secondary minerals of the uranite group occur in dense quartz veins and in altered aplitic granite along and near the crest of the east-trending ridge about one mile west of Clancy, Montana. Brief examination suggests that the radioactive minerals are erratically distributed, but a more thorough study of the area will be made by the Geological Survey during the coming field season.
