A low-background gamma spectrometer consists of a high-performance gamma detector and a low-background chamber. It is widely used to monitor the radiation level of the environment and to identify the species of the radiological source. It is especially important for the analysis of the nuclear accident. Usually a high purity Germanium detector (HPGe) is used as a gamma ray detector. In order to enhance the detecting accuracy and sensitivity, it is essential to improve the performance of the gamma detector. In recent years, a clover detector composed of four coaxial HPGe crystals appear and is widely utilized in nuclear physics experimental research. Because of the larger dimensions and segmented structure, it displays outstanding characteristics different from traditional HPGe detectors. With a clover detector as the main detector and the HPLBS1 chamber of ORTEC as the lead chamber, the low-background gamma spectrometer is simulated by the Monte Carlo toolkit GEANT4, where the interaction processes of gamma ray provided by the GEANT4 physics list is used. The detecting performance of the low-background gamma spectrometer such as detecting efficiency and peak-total ratio are given. The results indicate that low-background gamma spectrometer with a clover as the main detector has better characteristic than that with HPGe as a main detector traditionally.

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.
