摘要
目的通过系统检测一种热释光剂量测量系统的性能指标,全面评价该系统的可靠性。方法参照JJG 593-2006、GBZ207-2016和GB/T 10264-2014,对热释光剂量测量系统的批均匀性、稳定性、入射角响应、线性、能量响应、量值检验、残余剂量、探测限等8个指标进行了检测,并将检测结果与相关标准要求比对。结果各项性能指标检测结果满足国家及行业规定的指标限值。结论该热释光剂量测量系统符合相关标准要求,可以用于人与环境辐射剂量的测量工作。
Objective To evaluate the reliability of a thermoluminescence dosimetry system by testing the key performance indexes.Methods Under the criteria of JJG593-2006, GBZ207-2016, and GB/T10264-2014, eight indexes of the thermoluminescence dosimetry system were examined, including the batch homogeneity, stability, angle response, linearity, energy response, quantity inspection,residual dose, and the minimal detection limit. Moreover, the results were compared with the related standards. Results The results of various performance indexes met the criteria of the national and industrial standards. Conclusion The thermoluminescence dosimetry system meets the technical requirements of relevant standards, and can be used for personal and environmental dose monitoring.
