Airborne Radiometric Reconnaissance of Parts of Central Montana

Description: This report provides the results to an airborne radiometric reconnaissance made in central Montana, the Sweetgrass Hills and Arch area, and Clancy area of the Boulder batholith that was completed in October 1953. This report is divided into three parts, each area is discussed separately according to its geology, the airborne procedures employed, and the conclusions reached.

Airborne Radiometric Survey in Northern New Jersey and Southeastern New York

Description: Abstract: "An airborne radiometric survey of the pre-Cambrian Highlands of New Jersey and New York, and Triassic Newark Basin located in 14 radiometric anomalies in the Highlands. No commercial deposit of uranium discovered. Ground checks revealed that most anomalies were caused by large masses or residual boulders of slightly radioactive granitoid gneiss."

Airborne Reconnaissance in the Valley of Fire-Muddy Mountains Region, Nevada

Description: Abstract: The Valley of Fire-Muddy Mountains region, located 20 to 30 miles northeast of Las Vegas, Nevada, was given approximately 25-percent airborne radioactive coverage during the fall of 1954. Rocks in the area range from Cambrian to Miocene in age. Uranium was known to occur at two sedimentary horizons at the time the airborne program began. One new uranium-bearing sedimentary horizon was discovered by the airborne reconnaissance. Of 15 anomolies detected, only 11 were posted as the remai… more

Airborne Reconnaissance Project, Green River Basin, Wyoming

Description: Abstract: A part of the Green River Basin airborne reconnaissance project, re: memo to Phillip L. Merritt, March 12, 1954, Proposed Airborne Reconnaissance Project, Green River Basin, Wyoming, was completed during the months from July though October 1954. No uranium mineralization of commercial value was found.

Analysis of uranium hexafluoride-hydrogen fluoride solutions by freezing point determination : errors caused by liquid -vapor equilibrium

Description: A report detailing the analysis of uranium hexafluoride-hydrogen fluoride solutions by their freezing point determination. This analysis was conducted by measuring vapor pressures at the freezing temperatures of different compositions of uranium hexafluoride-hydrogren fluoride solutions.

Analytic Approach for the Pion-Proton Scattering Phase Shifts

Description: A simple method of solving for the phase shifts of the pion-proton scattering is presented. The rapid solution afforded can be utilized, as the Ashkin diagrams have been employed, to give starting values to an electronic computer or alternatively to analyze with more ease the variation of the phase shifts as a function of the input data in terms of the coefficients of the angular distributions. A new plot of a function of the total cross section versus the pion energy is introduced. The nearly … more

Angular Distribution of Fragments from the Photofission of U238

Description: Ilford D1 and Eastman NTC nuclear emulsions have been loaded with a solution of uranium acetate and them exposed to the X-ray beam of the Case betatron operated at 18 Mev. The developed plates have been searched wit a Zeiss type microscope. A total number of 1062 fission tracks have been measured and analyzed and the angular distribution of the fission fragments in center of mas system has been obtained.

Automatic Thermogravimetric Analysis in Ceramics

Description: Ceramic investigators often find it desirable to know the weight of reactants either immediately after a given heating period or while the specimen is still at the elevated reacting temperature. The conventional gravimetric methods render either of these goals difficult if not actually impossible. Specimens often gain weight through adsorption of water or other reactions upon cooling to room temperature. Desiccators are employed but are not completely satisfactory. Repeated heating and weighing… more

Beta Gage for Localized Measurements on Thin Films

Description: A gage employing a narrow "pencil" of beta-rays has been developed to determine the thickness of films used a cyclotron targets. The instrument, pictured in Figure 1, allows an estimate of the evenness of films a few mg/cm thick by reproducibly scanning the sample with a collimated beta-ray beam 3/32 in. in diameter.

Bonding of uranium to uranium

Description: From abstract: "Some mechanical properties of uranium joined to uranium by means of sinter welding described. The types of uranium investigated were powdered and cast material. Comparison of results obtained by the testing of the whole and joined material are presented. Although the joined material to date does not possess strength of the whole material, the results are promising. Work is continuing."

Carcinogenesis by Radioactive Substances

Description: Knowledge of the potential dangers of exposure to radioactive substances and the institution of proper safety precautions have helped to reduce accidental exposures to radioactive substances. In the following technical report we shall review briefly carcinogenesis in man by naturally occurring and artificially produced radioactive substances, the lung cancer problem in miners, the development of bone tumors in luminous dial painters and in patients treated with radium-containing nostrums, and t… more

A Cloud Chamber Study of the Secondary Particles from Locally Produced Penetrating Showers

Description: The present experiment was undertaken as an attempt to throw more light on the decay processes that had been observed prior to the summer of 1952, as well as to investigate any new decay processes that might manifest themselves. The source of high energy primary particles was to be the cosmic ray beam, so a detector of locally produced high energy penetration showers was used. In order to be able to detect effectively low energy photons and low energy secondaries from particles reaching the end… more

Continuous injection processing

Description: From introduction: "In this report we consider a few non-adiabatic processes. The types to be discussed will be limited because of two reasons: first, complete descriptions are available for some processes; second, as time goes on alternative injection methods undoubtedly will be discovered, so this list must necessarily be incomplete."
