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.

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

Carnotite-Bearing Sandstone in Cedar Canyon, Slim Buttes, Harding County, South Dakota

Description: From abstract: Carnotite-bearing sandstone and claystone have been found in the Chadron formation of the White River group of Oligocene age in the southern part of the Slim Buttes area, Harding County, S. Dak. The carnotite is an efflorescent yellow coating on lenticular silicified sandstone. Locally, the mineralized sandstone contains 0.23 percent uranium. The uranium and vanadium ions are believed to have been derived from the overlying mildly radioactive tuffaceous rocks of the Arikaree form… more

Chromite Deposits in Central Part Stillwater Complex, Sweet Grass County, Montana

Description: From abstract: The chromite deposits of the central part of the Stillwater complex lie in a belt 9 miles long between the valleys of Boulder River and the West Fork of the Stillwater River in Sweet Grass County, Mont. The chromite occurs as layers near the middle part of the ultramafic zone in the lower part of the complex. The layers, originally horizontal, have been tilted so that they dip northeastwards at angles ranging from nearly horizontal to nearly vertical, and are cut by many cross fa… more

Collected Reports on Fission Cross Sections of U237 in Thermal Neutron, Intermediate Neutron, and Degraded Fission Neutron Spectra

Description: Part 1. The neutron fission cross section of U237 has been measured in a thermal neutron spectrum and in a somewhat degraded fission spectrum. The fission cross section for thermal neutrons is found to be <2 barns; the ratio of the fission cross section of U237 to that of U235 in the degraded fission spectrum is found to be 0.476 +- 15% which corresponds to [formula] in this spectrum equal to 0.66 +- 0.10 barns. Part 2. The average neutron fission cross section of U237 has been measured in a ne… more

Contributions to General Geology 1951-54

Description: A report about stratigraphic studies of late Quaternary deposits in the Rocky Mountain region which reveal a widespread uncomformity separating deposits that differ lithologically. The deposits overlying the unconformity contain modern fauna that do not occur in older deposits.

Corrosive and Erosive Effects of Acid Mine Waters on Metals and Alloys for Mine Pumping Equipment and Drainage Facilities: Anthracite Region of Pennsylvania

Description: From Summary: "This report presents data on the corrosive and erosive effects of acid mine waters in the anthracite region on metals and alloys for pumping equipment and drainage facilities necessary to remove or control this water. This report is based on field tests conducted cooperatively by the Armco Steel Corp. and the Federal Bureau of Mines from January 1953 to June 1954 to determine the most suitable materials for constructing pumping equipment designed to handle these acid mine waters." more

Criteria for Outlining Areas Favorable for Uranium Deposits in Parts of Colorado and Utah

Description: Abstract: Most of the uranium deposits in the Uravan and Gateway mining districts are in the persistent upper sandstone stratum of the Salt Wash member of the Morrison formation. Areas in which this stratum is predominantly lenticular have been differentiated from areas in which the stratum is predominantly nonlenticular. The most favorable ground for uranium deposits is in areas of lenticular sandstone where the stratum is underlain by continuous altered greenish-gray mudstone. Ore is localize… more

Decay Scheme of In107

Description: The gamma radiations of In107 have been investigated with a scintillation spectrometer . The In107 was produced in a cyclotron by a (d,n) reaction on electromagnetically enriched Cd106. Beta-gamma and y-y coincidence experiments showed in addition to the annihilation radiation, only one y ray of 0.22 Mev associated with the 2.2 Mev positron.

The Decomposition of Solid Barium Nitrate by Gamma Rays

Description: There was considerable disagreement between results obtained by early investigators who studied the interaction of ionizing radiations with solid nitrates. It was thought worthwhile, therefore, to extend their work and to make certain that reproducible results were being obtained. It was expected that the nitrite ion and oxygen would be found in equivalent amounts in the irradiated samples. Four measurements of nitrite ion and oxygen indicate that the decomposition of barium nitrate by gamma r… more

Denitration Loss of Ruthenium from Uranyl Nitrate Beta Mounts

Description: Abstract: "During the preparation of beta-gamma mounts of uranyl nitrate it is possible to affect a denitration loss of approximately 80% of the ruthenium. By adding hydroxylamine sulfate and sulfuric acid, the ruthenium is stabilized and the denitration loss is eliminated. The standard determination of ruthenium by calculation, utilizing a differential counting technique has been found to be approximately the same as the standard denitration of radiochemical assays."

Development of a Furnace for Melting and Casting Uranium Metal

Description: Introduction: "At the start of the uranium project, it became necessary to design and construct a furnace suitable for melting and casting uranium powder into massive form. Early experiments showed that pressed and sintered compacts of uranium powder were inferior to the cast metal. Since the metal powder is quite phrophoric, such casting would have to be done in an inert atmosphere or in vacuum. Preliminary investigations indicated that the powder could be melted in vacuum induction furnace. F… more

Effects of X-Irradiation on the Plasmas of Chickens as Revealed by Serological Analysis. Part I, Whole Plasma Comparisons. Part II, Alteration of Proteins of the Liver (a Preliminary Report). Part III, Autoantibody Formation (a Preliminary Report)

Description: Irradiation of a living animal with X-rays induces alternation in the proteins of cells in which ionization events occur. Systematic end-products such as the proteins of plasma would, by changes in quality and quantity divulge modification of their synthetic pathways, or compensatory responses of the hematopoietic systems to stresses caused by irradiation in other organs. Serological identification of proteins, a sensitive means of biochemical characterizations was chosen to reveal variations i… more
