Abstract

The aim of this paper is to examine the energy and angular responses of thermoluminescent dosimeters containing either MTS-N (LiF:Mg,Ti) or MCP-N (LiF:Mg,Cu,P) detector materials, and of the InLight optically stimulated luminescent dosimeters containing AlO:C detectors. Ten radiation qualities, with mean energies ranging from 24 keV to 1.25 MeV, and five angles of incidence, between 0° and 80°, were used for this purpose. The dosimeter response measure of quality were the IEC 62387 requirements. The experimental results show that the MTS-N-based and the InLight dosimeters performed in line with the standard's criteria. On the other hand, the MCP-N-based dosimeters exhibited a pronounced under-response around the energy of 120 keV, which resulted in deviations from the standard's conditions for both the energy and angular responses.

摘要

本文旨在研究含有MTS-N（LiF:Mg,Ti）或MCP-N（LiF:Mg,Cu,P）探测器材料的热释光剂量计以及含有AlO:C探测器的InLight光激励发光剂量计的能量响应和角响应。为此，使用了十种辐射品质，其平均能量范围为24 keV至1.25 MeV，以及五个入射角，介于0°和80°之间。剂量计质量响应测量符合IEC 62387要求。实验结果表明，基于MTS-N的剂量计和InLight剂量计的性能符合标准标准。另一方面，基于MCP-N的剂量计在120 keV能量附近表现出明显的响应不足，这导致能量响应和角响应均偏离标准条件。
