In this study, the thermoluminescence properties of natural calcite samples were examined in detail. The glow curve of the sample irradiated with beta radiation shows two main peaks, P1 (at 115 °C) and P4 (at 254 °C). The additive dose, variable heating rate, computer glow curve deconvolution, peak shape and three point methods have been used to evaluate the trapping parameters, namely the order of kinetics (b), activation energy (E) and the frequency factor (s) associated with the dosimetric thermoluminescent glow peaks (P1 and P4) of natural calcite after different dose levels with beta irradiation.
在本研究中，对天然方解石样品的热释光特性进行了详细研究。用β辐射照射的样品的发光曲线显示出两个主要峰，P1（在115℃）和P4（在254℃）。采用附加剂量法、可变加热速率法、计算机发光曲线解卷积法、峰形法和三点法来评估俘获参数，即与经不同剂量水平β辐射后的天然方解石剂量热释光发光峰（P1和P4）相关的动力学级数（b）、活化能（E）和频率因子（s）。
