From abstract: "The design of a scintillation counter for measuring radioactive contamination of hands and feet is described."

From abstract: A sweep unit for automatic control of single channel pulse height analyzer bias is described. The unit is linear, stable, and compact enough to be included in most single channel pulse height analyzers. Several applications of the sweep unit to scintillation spectroscopy are described.

Abstract: The fast and thermal neutron leakage from the 30 megawatt SGR-P4 reactor has been studied by three independent methods.

Report describing reactor components, operational characteristics, and operating instructions for the Model L-3 research reactor.

From abstract: An electromechanical automatic count and control unit for a beta-ray spectrometer is described. The count control unit provides for constant or time limited recording of data and actuates an automatic stepping system which sweeps a well regulated motor generator power supply over 100 increments of focusing magnet current.

Abstract: Field and laboratory study of primary sedimentary features of the Salt Wash sandstone was undertaken to learn if these structures can be of use in finding hidden deposits of ore and also if they have influenced the localization of either individual ore deposits or larger mineralized districts.

Abstract: The objectives of this study have been to determine the nature of the major fracture pattern of the Zuni uplift; to analyze this pattern for evidence of the mode of origin of the uplift; and to compare the fracturing in the ore areas with that elsewhere on the uplift to see whether diagnostic features exist hat might make it possible to indicate other favorable areas.

Objectives: The purpose of this project was to study in detail the factors controlling the formation of fractures and the fracture pattern actually developed in an area transitional between Colorado Plateau and Basin and Range type structures.

Abstract: The Trans-Pecos region of southwest Texas is noted for the production of quicksilver, lead, silver, and copper from its several mining districts. Reconnaissance, which was concentrated in and around these districts, revealed many areas of slightly abnormal radioactivity. Only a few areas, however, showed uranium mineralization.

Introduction: The investigation of monazite deposits in the southeastern states by the Bureau of Mines and the Geological Survey on behalf on the U.S. Atomic Energy Commission was prompted by the history of past production and the many communications reporting the occurrence of monazite in this area.

Introduction: This volume is the second in a series of reports dealing with the recovery of uranium, alumina, and phosphatic values from the leached zone portion of he Florida phosphate producing area.

Summary: Process design and cost estimates for the digestion, leaching and filtration steps of plants which produce 450, 225, and 100 tons of uranium per year are presented in this report.

From abstract: Experimental simulation of Colorado Plateau type uranium deposits is divided into seven parts. The first three summarize the essential features of geological occurrence for the ores. The last four parts outline the results of experimental investigation arranged according to each geological group of features influencing mode of occurrence.

From abstract: Report of two typical two-story wood-frame houses subjected to a 16.4-kt atomic bomb.

From introduction: This report is a technical evaluation of four reactor power plant designs proposed by various AEC contractors.

From abstract: The area comprising the first flood plain downstream from the headwaters of Knob Creek was one of three monazite placer deposits near Shelby, N. C., recommended by the Geological Survey for investigation by the Bureau of Mines as a joint effort by the above two agencies. Past production of monazite from the headwaters of this stream and its drainage of an area of known source rocks were factors influencing this selection. Drilling of the deposit was started on November 26, 1951, and completed December 29, 1951. Twenty-two churn-drill holes were completed to bed-rock on 112 acres of this flood plain for a total depth of 433 feet of vertical drilling.

Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

Abstract: An exploratory wagon drilling program was conducted from May 2, 1953, to October 31, 1953, on the Silver Crown, Big Hill, and Silverman claims of Western Gold and Uranium Mines, Inc. at the Silver Reef district near Leeds, Utah. Two economically significant new ore bodies were discovered and considerable geological information gained. The Silver Reef uranium deposits are located near the faulted north-plunging nose of the Virgin anticline in an old silver mining' district. Silver, uranium, vanadium, and copper minerals occur in association with various carbonaceous, sandy shale horizons of the Leeds and Tecumseh members of the Triassic Chinle formation. Mineralization has favored areas where relatively close-spaced normal faults of very small displacement cut the favorable beds.
