The glow curve of LiF:Mg, Ti (TLD-100) has a well known and defined shape. Several factors, however, can distort the glow curve shape and can lead to incorrect dosimetry. Only proper evaluation of glow curves, either by visual inspection or computerized method, can detect these anomalies. Visual observation is riot only tedious and time consuming but may also be susceptible to human errors. The usefulness of a commercially available glow curve analysis software during quality control testing of thermoluminescence dosimetry cards is discussed. The long-term stability of the thermoluminescence dosimetry reader is also investigated using this software. Various types of glow curve anomalies encountered during routine personal dosimetry practice are presented.
LiF:Mg,Ti（TLD - 100）的发光曲线具有众所周知且明确的形状。然而，有几个因素会使发光曲线形状失真，并导致剂量测定错误。只有通过目视检查或计算机化方法对发光曲线进行恰当评估，才能检测到这些异常情况。目视观察不仅繁琐且耗时，还可能容易出现人为误差。本文讨论了一种商用发光曲线分析软件在热释光剂量测定卡质量控制测试中的作用。还使用该软件研究了热释光剂量测定仪的长期稳定性。文中介绍了在常规个人剂量测定实践中遇到的各种类型的发光曲线异常情况。
