Gamma Ray Spectrometer Data Processing Programs


Book Description

Two computer programs have been written to analyze and display (plot) the spectral output of two different gamma-ray spectrometers. These spectrometers are the anti-Compton spectrometer currently in use in NOL's Van de Graaff facility and the Deep Underwater Nuclear Counter (DUNC). Both programs have been written for use with an IBM 7090 computer. The program for the anti-Compton spectrometer adds (subtracts) in variable amounts spectra which are stored in one half of a multichannel analyzer to those stored in the other half. It also performs necessary energy or total count normalization, calculates statistical errors and displays the processed data on linear or semi-logarithmic plots. The DUNC program is used to prepare magnetic tape from a paper punch tape output of a multichannel analyzer. It also searches the magnetic tape for spectra to be normalized, operated upon arithmetically and displayed in printed, punched card or graphic form on the CalComp plotter. (Author).




Practical Gamma-ray Spectroscopy


Book Description

The Second Edition of Practical Gamma-Ray Spectrometry has been completely revised and updated, providing comprehensive coverage of the whole gamma-ray detection and spectrum analysis processes. Drawn on many years of teaching experience to produce this uniquely practical volume, issues discussed include the origin of gamma-rays and the issue of quality assurance in gamma-ray spectrometry. This new edition also covers the analysis of decommissioned nuclear plants, computer modelling systems for calibration, uncertainty measurements in QA, and many more topics.







Revised Anticoincidence-shielded Gamma-ray Spectrometer Data-processing Program


Book Description

A program is described which processes and plots data accumulated by an anticoincidence-shielded scintillation spectrometer. This program is similar to that described in AD-611 198, except that an error in some statistical uncertainty calculations has been corrected, provision has been made for the subtraction of a common background spectrum from a number of input spectra submitted at one time but as separate problems, and spectra are all plotted with a common energy scale to permit the accumulation of a library of easily usable standard spectra. Also, the plotting routine has been changed so that for each energy channel the number of counts and the uncertainty thereof are represented by a datum point and uncertainty bar rather than by three data points. Provision has also been made for automatic labeling of all graphs and for labeling of the vertical axes. (Author).




Applied Gamma-Ray Spectrometry


Book Description

Applied Gamma-Ray Spectrometry covers real life application of the gamma-ray and the devices used in their experimental studies. This book is organized into 9 chapters, and starts with discussions of the various decay processes, the possible interaction mechanisms of gamma radiation with matter, and the intrinsic and extrinsic variables, which affect the observed gamma-ray and X-ray spectra. The subsequent chapters deal with the properties and fabrication of scintillation detectors, semiconductor detectors, and proportional gas counters. These chapters present some of the most widely utilized applications of these detectors, with a particular emphasis to the activation analysis. These topics are followed by reviews of the description of basic equipment, such as amplifiers, analyzers, special spectrometer arrangements, and detector shielding. Other chapters describe energy and time resolution and quantitative calibration. The quantitative and qualitative interpretation of the spectra is also explained, along with the calibration of the detectors. The last chapter considers the analytical applications of gamma-ray and X-ray spectrometry in tracer studies, activation analysis, fission product studies, and X-ray fluorescence analysis. This book will be of value to analytical chemists and analytical chemistry researchers.













Practical Gamma-ray Spectrometry


Book Description

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 detectors, 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.
