摘　　要：使用热释光探测器进行辐射剂量监测是目前中国个人或环境剂量监测的主要方法之一。为解决热释光探测器在使用前需进行均匀性筛选以及测量过程复杂的问题,通过引入试验剂量,对热释光峰计数进行归一化处理,消除了热释光探测器剂量响应差异的影响,优化了现行热释光剂量的测量流程。配合简易辐照装置,使用优化测量流程和现行一般测量流程对同一批辐射环境监测的热释光剂量计进行测量,两者剂量值相对误差处于±5%以内,能够满足热释光剂量计在个人或环境电离辐射剂量监测过程中的准确度要求。并且优化后的热释光剂量测量流程无需均匀性筛选,降低了探测器均匀性性能要求,提升了测量流程的适用性,为中国的个人或环境剂量监测提供了一种高精度、高效率、低成本的测量方法。Radiation dose monitoring using thermoluminescent detectors is currently one of the main methods of personal or environmental dose monitoring in China.In order to solve the problem of uniformity screening before the use of thermoluminescent detector,and the complexity of the measurement process.Test dose and thermoluminescent peak counts normalization were used to optimize the measurement process of thermoluminescent detectors.With the simple irradiation device,the same batch of thermoluminescent dosemeters for radiation environment monitoring were measured using the optimized and general measurement processes.The relative error of the dose values of the two was within±5%,which satisfied the accuracy requirements of thermoluminescent dosemeters in the process of monitoring the dose of ionizing radiation to the individual or the environment.The results show that the optimized thermoluminescent dosimetry process reduces detector uniformity performance requirements and improves the applicability of the process.It provides a high-precision,high-efficiency and low-cost measurement method for personal or environmental dose monitoring in China.
