Assessing an accuracy of vgspec program through ability of calculating peak area, automatically finding the peak, identifying isotopes and determining radioactivity for cylindrical and marinelli sources

Abstract

Genie 2000 version of gamma spectrum processing program, which is being used at Nuclear Physics Department, Physics – Technique Physics Faculty, University of Science is lacked of package for determining radioactivity of sources, also has not been comprehensibly automatic from analysis and process to identification of radioactive isotopes and evaluation of source activity. We have built version 2.1 of VGSpec program to determine source radioactivity. Then, the experiments are carried out to measure cylindrical standard and Marinelli samples by low background gamma spectrometer using HPGe detector, to compare experimental results with ones of the program, as well as assess the accuracy of VGSpec program through ability of determining radioactivity for cylindrical and Marinelli sources.
