Abstract Green quartz is usually studied for low dose TL dosimetry of gamma and X radiation. The aim of the present work is the dosimetric characterization of natural green quartz in the dose range of 0.47 mGy up to 1000 mGy of gamma and X radiation. Green quartz pellets were produced by cold pressing green quartz powder. The pellets are very sensitive to gamma and X radiation with main prominent TL peak at 230 °C. The TL sensitivity of MTS-N (LiF:Mg,Ti) and green quartz pellets were also compared. The dose response curve presented linear behavior in the dose range studied. The glow curve was deconvoluted. Kinetic parameters such as trap depth, kinetic order (b) and frequency factor (s) are determined. The TL photon energy dependence was also evaluated.

用于低剂量剂量测定的绿色石英小球的热释光研究

摘要 绿石英通常用于伽马和X 辐射的低剂量TL 剂量测定。目前工作的目的是在 0.47 mGy 至 1000 mGy 伽马和 X 辐射的剂量范围内对天然绿色石英进行剂量学表征。绿色石英颗粒是通过冷压绿色石英粉生产的。颗粒对伽马和 X 辐射非常敏感，主要突出的 TL 峰位于 230 °C。还比较了 MTS-N (LiF:Mg,Ti) 和绿色石英颗粒的 TL 灵敏度。剂量反应曲线在所研究的剂量范围内呈现线性行为。辉光曲线是去卷积的。确定了陷阱深度、动力学顺序 (b) 和频率因子 (s) 等动力学参数。还评估了 TL 光子能量依赖性。
