Viscosities and Densities of Fluorolube Oils

Description: Abstract: Since the viscosity-temperature relationships of fluorocarbons are somewhat unusual, when compared to hydrocarbons, for example, it was decided to measure the viscosities, at several temperatures, of various fluorolube oils. The calculation of the viscosity of a blend of oils is at best an uncertain operation, varying considerably with the method used. A comparison of various methods was indicated, in order that reasonably accurate values might be assumed for theoretical composites.… more

Modified Simpson Methane Flow Proportional Alpha Counter and Fission Counter

Description: Abstract: This technical report consists of series of drawings of the instrument with the following explanation. The modification of the Simpson Methane flow proportional counter consists of a means for inserting and replacing samples into the chamber through an air-lock device which avoids the introduction of even a small quantity of air into the active volume of the chamber. This is accompanied by sweeping out the small volume of the air-lock containing the sample with methane gas before the… more

Note on the Determination of Lead in Pitchblende

Description: Technical report describing a procedure for the determination of lead in pitchblende. The procedure was determined as needed in the course of an investigation of the processing of pitchblende for the production of uranium. Summary: The volumetric dichromate method for the determination of lead was selected from among several methods investigated as being best suited for a rapid determination of lead in pitchblende. The method as described is accurate to within 1% and it does not require the … more

The Toxicity and Metabolism of Plutonium in Laboratory Animals

Description: Introduction. The main objective of the Metallurgical Project was the preparation of large quantities of plutonium 239, an isotope of element 94, by the interaction of neutrons and uranium. At the beginning, only predictions of its chemical and biological properties could be made since it is a new element. It was predicted that it would be toxic to tissue by virtue of its high atomic weight, and in addition, that it would be toxic by virtue of its radioactivity. Thus, the preparation and use… more

Crystal Structure Studies of the System NaF-UF4, NaF-ThF4 and NaF-LaF3

Description: Abstract: In the NaF-UF4 system the following intermediate phases have been found: NaUF5, -Na2UF6, -Na2UF6 and NacUF7. NaLaF4 is the only intermediate phase observed in the system NaF-LaF3. In the course of an incomplete study of the system NaF-ThF4 the phases NaTh2F9, -Na2ThF6, -Na2ThF6 and Na4ThF8 have been observed. Crystal structure data are given for all the phases.

Use of Redux Adhesives for Bonding Metal

Description: Redux is a thermosetting synthetic resin manufactured by the Resinous Products & Chemical Co., Washington Square, Philadelphia 5, Pa. According to the manufacturer, it is intended for bonding metal to metal and metal to wood. It was apparently intended to replace rivets in aircraft structural parts and recent information indicates that a British airplane, the DeHaviland Dove, is in production using this resin. The adhesive was originally developed in England by Aero research Ltd. Experience a… more

The Emf of Cells with Uranium: Uranium Halide Couples in Fused Salt Electrolytes

Description: The emf of galvanic cells at high temperatures was measured using uranium metal in equilibrium with its chloride as one half of the cell, the other half of the cell being some reference electrode such as silver - silver chloride. Several designs of cells tried are described. A value of 2.83 volts/eq. at 1170[degree]K and also at 990[degree]K is considered as the most probably value for the potential of the uranium halide couple.

Effects of Total Body Z Irradiation of Rats. Part I, Lethal Action of Single, Paired, and Periodic Doses

Description: Abstract: Exposure of Sprague Dawley white rats to single doses of 900 kvp X radiation demonstrated a medium lethal dose of 600 r which was not markedly dependent upon sex, weight, or, in the case of females, stage of the estrous cycle at the time of irradiation. Deaths within 30 days were most frequent between the fourth and eighth, and between the tenth and fifteenth post- irradiation days, indicating the existence of at least two processes leading to death in the "acute" period.
