Airborne Radioactivity Surveys in Geologic Exploration

Description: The following report describes the use of airborne radioactivity surveying and analytical techniques in geologic exploration by examples of the analysis or evaluation of airborne data related to specific geologic settings. The airborne radioactivity surveying program was begun in 1949 by the U.S. Geological Survey to assist in uranium exploration.

Progress in Airborne Radioactivity Surveying

Description: From abstract: The objectives in the investigation of airborne radioactivity surveying during fiscal year 1951 were: 1) Establishment of a routine technique of airborne radioactivity surveying -- completed by incorporating those phases of the aeromagnetic surveying technique that were applicable; 2) Development of automatic correction of the radiation measurement for variation in distance from source -- achieved by using the radar altimeter output to modify the output of the counting-rate meter in accordance with the observed variation of radiation intensity with distance from a source; 3) Development of more efficient radiation detectors -- including large scintillation detectors.

Uranium Series Disequilibrium in Radioactive Ores

Description: From introduction: The purposes of this paper are to tabulate and discuss the results of a number of complete disequilibrium analyses, to illustrate a proposed classification of disequilibrium patterns, to study these disequilibria as clues to the understanding of the geochemical history of the samples and of the deposits, and to point out some of the difficulties when simply comparing radioactivity and chemical uranium assays for interpreting equilibrium or disequilibrium in samples.

The Ratio of Alpha to Beta Activity of Natural Atmospheric Radioactivity

Description: Abstract: The alpha to beta ratio of naturally occurring radioactivity in the air has been investigated. The study has concerned itself primarily with radon daughter products collected on filter-paper samples from the time equilibrium has been established on the paper through elapsed times during which radioactive counting is normally accomplished. Calculations showing the change in this ratio of activities during the above period are presented. From this work it appears that the observed constancy of ratio does have theoretical justification and that departures in alpha-to-beta ratio would be a usable approach to the detection of long-lived alpha or beta radioisotopes in the atmosphere.

Determination of Radiocesium with Chloroplatinic Acid

Description: The following report examines a rapid method used to eliminate the possibility of explosive perchlorate-organic mixtures in a control laboratory in order to determine radiocesium. These methods include the usage of chloroplatinic acid as a precipitate of radocesium.
