目的对国内常见不同类型的个人剂量仪性能进行测试与评价。方法根据GB/T 12161-2003《直读式个人X和γ辐射剂量当量和剂量当量率检测仪》与检定规程JJG 1009-2006的相关要求,使用中国辐射防护研究院放射性计量站的γ和X射线照射量标准参考辐射装置。结果分别对不同型号的X、γ个人剂量仪的相对固有误差、重复性、角度响应、报警声响和能量响应进行了的性能测试及分析比对。结论表明前三项测试结果较理想,而近75%的仪器能量响应不能满足国家标准及检定规程的要求。
Objective To test and evaluate the performance of different types of personal dose meters in China. Methods According to GB / T 12161-2003 “direct reading personal X and gamma radiation dose equivalent and dose equivalent rate detector” and test procedures JJG 1009-2006 the relevant requirements of the China Institute of Radiological Protection Radiometric measurement station γ and X Radiation dose standard reference radiation device. Results The relative inherent errors, repeatability, angular response, alarm sound and energy response of different types of X, γ personal dosimeters were tested and analyzed respectively. The conclusion shows that the first three test results are satisfactory, and nearly 75% of the instrument energy response can not meet the requirements of national standards and test procedures.
