GAMMA SPECTRA DATA PROCESSING PROGRAMS.


Book Description

The FORTRAN IV programs for processing spectra (number of events per energy interval histograms) include: GAMMA, which normalizes the zero intercept and energy per interval; SPEC, which determines quantitatively the redioisotopes in the spectra by sequential subtraction of standard spectra; MONTE CARLO, which produces standard spectra for a given detector and incident energy; and MERGE, which combines standard spectra of various energies to duplicate the spectrum of a radioisotope. GAMMA, MERGE, AND SPEC will work for any consistent set of histograms, while MONTE CARLO contains parameters for a sodium iodide (thallium) gamma-ray detector in an infinite medium containing a uniformly distributed source. The programs are used to analyze the concentration of radioisotopes in water. (Author).

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.
