The thermoluminescent Na-doped BeO phosphor (Panasonic UD-170A) is one of thebetter thermoluminescent dosimeters due to its high sensitivity, tissue equivalency, andrepeatability. However, there have only been a few reports on thermoluminescence (TL) glowcomponent analysis, despite this being necessary to understand the physical characteristicsof thermoluminescent phosphors based on BeO. In this study, the TL glow curve of thethermoluminescent Na-doped BeO phosphor was analyzed using a postannealing method with avery low heating rate of 0.1 °C s−1. Although the TL glow curve for thermoluminescent Na-dopedBeO phosphor was previously reported to consist of only a few components, our investigationanalyzed at least thirteen components in the TL glow curve. In addition, the accuracy of the TLparameters calculated in this study was very high using a postannealing method with a very lowheating rate.
