Abstract LiF:Mg,Ti thermoluminescent dosimeters (TLDs) are frequently used for personal dosimetry by individual monitoring services (IMS) all over the world. This study focused on the investigation and accurate description of thermoluminescent signal fading in these dosimeters. The routine readout procedure was performed with the controlled heating of the detector elements according to defined time-temperature profiles (TTPs). The output of this procedure was a temperature dependent light signal, called glow curve. Additionally, the readout optimization was achieved with the simulation and validation of glow curves with different fast readout TTPs. The TLDs were annealed, irradiated and read out with different storing times at an ambient temperature of 25 °C. Six batches of each 100 TLDs were irradiated and read out with different TTPs and compared afterwards. A fading study with several Harshaw TLD-100 dosimeters was performed, in which the results were responses to describe the pre-irradiation fading and the post-irradiation fading with mathematical functions that give a correction factor for the dose calculation.

用于个人剂量测定的 LiF:Mg,Ti 热释光探测器常规使用的衰落研究和读数优化

摘要 LiF:Mg,Ti 热释光剂量计 (TLD) 经常被世界各地的个人监测服务 (IMS) 用于个人剂量测定。本研究侧重于对这些剂量计中热释光信号衰落的调查和准确描述。根据定义的时间-温度曲线 (TTP)，通过对检测器元件进行受控加热来执行常规读出程序。该程序的输出是温度相关的光信号，称为辉光曲线。此外，通过模拟和验证具有不同快速读出 TTP 的辉光曲线，实现了读出优化。在 25 °C 的环境温度下，以不同的存储时间对 TLD 进行退火、辐照和读取。每 100 个 TLD 对 6 个批次进行辐照并用不同的 TTP 读出，然后进行比较。使用几个 Harshaw TLD-100 剂量计进行了衰落研究，其中结果是描述辐照前衰落和辐照后衰落的响应，数学函数给出了剂量计算的校正因子。
