The synthesis and thermoluminescence (TL) characterization of self-agglomerating pellet-shaped CaSO phosphors, through a low cost and environmentally friendly method is reported. In order to investigate their TL features, some samples were exposed to beta particle irradiation in the dose range from 0.07 to 10 Gy. Characteristic TL glow curve consists of a single main maximum located at 216 °C, which is considered stable, hence, suitable for dosimetry applications. The dose-response was remarkable linear. Moreover, the lower detection limit was determined to be 6.0 μGy, and the relative TL sensitivity twice the one from the commercial TLD-100 dosimeter.
报道了通过一种低成本且环保的方法合成自团聚颗粒状硫酸钙（CaSO）磷光体及其热释光（TL）特性。为了研究它们的热释光特性，一些样品在0.07至10 Gy的剂量范围内接受β粒子辐照。特征热释光发光曲线由位于216°C的单个主要峰值组成，该峰值被认为是稳定的，因此适用于剂量测定应用。剂量响应呈显著线性。此外，确定下限检测限为6.0μGy，相对热释光灵敏度是商业TLD - 100剂量计的两倍。
