Book Description
The Geological Survey of Canada has been involved with the calibration of ground and airborne gamma-ray spectrometers since it constructed the first calibration facility for airborne spectrometers in 1968. Recent analysis of the calibration data obtained from the GSC facilities at Uplands airport, Ottawa, showed that the calibration constants were poorly known because of uncertainties in the radioelement concentrations of the pads. To improve the Canadian calibration facilities for both ground and airborne gamma-ray spectrometers, small sets of transportable pads 1 m x 1 m x 30 cm and weighing about 675 kg were constructed specially for calibrating portable spectrometers in the summer of 1988. Because of problems of radon leakage and inhomogeneities in the pads, a new set of uranium pads was constructed in the summer of 1989. This paper describes the design and construction of these small transportable pads and shows how they can be used for the calibration of both ground and airborne gamma-ray spectrometers.

Book Description
A high-sensitivity aerial gamma-ray spectrometer and magnetometer survey was conducted in the lower Yukon River and Kuskokwim River areas of southwestern Alaska (covering fifteen quadrangles) and in the middle Yukon River valley in Interior Alaska (covering eight quadrangles) as part of the National Uranium Resource Evaluation (NURE) Program of the United States Energy Research and Development Administration (ERDA). This program provides information on reconnaissance radioelement distribution to assist in assessing the uraniferous material potential in the United States. The analysis includes medium values of eU, eTh, and K (equivalent uranium, thorium, and potassium) contents of geological units.

Book Description
Airborne gamma-ray data from Malawi, Africa were used to develop an automated system for computing on-line atmospheric background radioactivity. The atmospheric backgrounds were calculated using lead-shielded upward-looking detectors calibrated from airborne measurements over a large lake and areas with varying proportions of uranium and thorium. The method was tested by producing atmospheric uranium background maps and background corrected uranium count rate maps from two different areas.

Book Description
Treatise on Geophysics, Second Edition, is a comprehensive and in-depth study of the physics of the Earth beyond what any geophysics text has provided previously. Thoroughly revised and updated, it provides fundamental and state-of-the-art discussion of all aspects of geophysics. A highlight of the second edition is a new volume on Near Surface Geophysics that discusses the role of geophysics in the exploitation and conservation of natural resources and the assessment of degradation of natural systems by pollution. Additional features include new material in the Planets and Moon, Mantle Dynamics, Core Dynamics, Crustal and Lithosphere Dynamics, Evolution of the Earth, and Geodesy volumes. New material is also presented on the uses of Earth gravity measurements. This title is essential for professionals, researchers, professors, and advanced undergraduate and graduate students in the fields of Geophysics and Earth system science. Comprehensive and detailed coverage of all aspects of geophysics Fundamental and state-of-the-art discussions of all research topics Integration of topics into a coherent whole
