Available in PDF, EPUB and Kindle. Book excerpt: A portable gamma ray detection apparatus having a gamma ray detector encapsulated by a compact isolation structure having at least two volumetrically-nested enclosures where at least one is a thermal shield. The enclosures are suspension-mounted to each other to successively encapsulate the detector without structural penetrations through the thermal shields. A low power cooler is also provided capable of cooling the detector to cryogenic temperatures without consuming cryogens, due to the heat load reduction by the isolation structure and the reduction in the power requirements of the cooler. The apparatus also includes a lightweight portable power source for supplying power to the apparatus, including to the cooler and the processing means, and reducing the weight of the apparatus to enable handheld operation or toting on a user's person.

This book was released on 1997 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilizing a portable spectroscopy system, a quantitative method for analysis of samples containing a mixture of fission and activation products in nonstandard geometries was developed. The method can be used with various sample and shielding configurations where analysis on a laboratory based gamma spectroscopy system is impractical. The portable gamma spectroscopy method involves calibration of the detector and modeling of the sample and shielding to identify and quantify the radionuclides present in the sample. The method utilizes the intrinsic efficiency of the detector and the unattenuated gamma fluence rate at the detector surface per unit activity from the sample to calculate the nuclide activity and Minimum Detectable Activity (MDA). For a complex geometry, a computer code written for shielding applications (MICROSHIELD) is utilized to determine the unattenuated gamma fluence rate per unit activity at the detector surface. Lastly, the method is only applicable to nuclides which emit gamma rays and cannot be used for pure beta emitters. In addition, if sample self absorption and shielding is significant, the attenuation will result in high MDA's for nuclides which solely emit low energy gamma rays. The following presents the analysis technique and presents verification results demonstrating the accuracy of the method.

Available in PDF, EPUB and Kindle. Book excerpt: Compact, rugged, efficient, and reliable room-temperature gamma ray detectors with better energy resolution are need for in situ applications. These improved detectors are sought as alternatives to the compact NaI(T1) detectors now available. A promising approach is an elegant new design that benefits fully form the recent advances in solid-state materials technology for production of large, good quality crystals of CdZnTe for room-temperature gamma ray spectroscopy. The new detector, equipped with simple but innovative electrode technology to address intrinsic charge-collection deficiencies, operates with the new self-contained portable gamma spectroscopy system, the miniature modular multichannel analyzer (M3CA), without added layers of electronic complexity for pulse processing. Applications of in situ NDA for portable determinations of fixed uranium and plutonium quantities and the continuous assay of dynamic quantities of these materials will provide the test criteria for evaluating the performance of such detectors operating with the M3CA.

Available in PDF, EPUB and Kindle. Book excerpt: The cutting-edge new edition of the classic introduction to radioactive measurement Gammy-Ray Spectrometry is a key technique in the study of radioactive decay. It measures the rate and extent of radioactivity from a variety of sources, both natural and artificial, including cosmic ray sources, nuclear reactors, high-energy physics experiments, and more. The resulting data can be essential to environmental monitoring and to a range of experimental sciences. For years, Practical Gamma-Ray Spectrometry has served as the classic introduction to this area for current or aspiring practitioners. A comprehensive but accessible treatment of the subject, with a thorough discussion of all major classes of detectors and their associated electronic systems, it contains everything a researcher needs to make optimal gamma-ray measurements. Now fully updated to reflect the latest technology and experimental data, it is a must-own for researchers looking to incorporate gamma-ray spectrometry into their scientific practice. Readers of the third edition of Practical Gamma-Ray Spectrometry will also find: Fault-finding guide for rapid and effective problem resolution Workshop-style approach emphasizing the fundamentals of laboratory practice New sections dealing with novel developments in nuclear structure research, measuring effects of pollution and climate change, new semiconductor materials, and more Practical Gamma-Ray Spectrometry is ideal for PhD students and practicing gamma-ray spectroscopists, including researchers working on radiation, energy and environmental monitoring professionals, and researchers working in physics, archaeometry, and related subjects.

Download or read book Transportable Calibration Pads for Ground and Airborne Gamma ray Spectrometers written by R. L. Grasty and published by Geological Survey of Canada. This book was released on 1991 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
