Abstract

Quality control of a laboratory process has become a reliable tool for monitoring and obtaining results that provide evidence of the stability of a measuring system. Gamma spectrometry is no exception. Moreover, establishing an internal quality control program ensures valid results regarding the long-term stability of the semiconductor measuring system. In this paper, we present the results of internal quality control performed on the HPGe detector over the period from 2010 to 2022. During this time, net peak area, Full Width at Half Maximum (FWHMs), Full Width at Tenth Maximum (FWTMs), and FWTM/FWHM ratio, as well as the total number of counts in the background were monitored and analysed. For this purpose, two point sources (⁶⁰Co and ¹³⁷Cs) were used. The obtained results demonstrate that adhering to good laboratory practice and implementing a properly established internal quality control program enables the identification of irregularities in the operation of the detector system and facilitates timely corrections, thereby ensuring the reliability of the HPGe detector system.

通过内部质量控制程序对半导体HPGe探测器系统进行长期分析- 13年随访

实验室过程的质量控制已成为监测和获得结果的可靠工具，这些结果为测量系统的稳定性提供了证据。伽马能谱法也不例外。此外，建立内部质量控制程序，确保半导体测量系统的长期稳定性的有效结果。在本文中，我们介绍了2010年至2022年期间对HPGe探测器进行内部质量控制的结果。在此期间，对净峰面积、半峰全宽（FWHMs）、十分峰全宽（FWTMs）、FWTM/FWHM比值以及背景计数总数进行了监测和分析。为此，使用了两个点源（60Co和137Cs）。结果表明，坚持良好的实验室规范，实施适当建立的内部质量控制程序，可以识别探测器系统运行中的违规行为，并及时纠正，从而确保HPGe探测器系统的可靠性。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
