The main objective of this study was to carry out a direct performance comparison among some known types of TLDs-three types of CaSO(4):Dy pellets, sintered Al(2)O(3) pellets, LiF:Mg,Ti (Harshaw TLD-100), CaF(2):Dy (Harshaw TLD-200) and CaF(2):Mn (Harshaw TLD-400)-in the energy and dose ranges of diagnostic radiology beams. Several dosimetric characteristics were evaluated, such as reproducibility, sensitivity, calibration curves, lower dose limits and energy dependence.
本研究的主要目的是在诊断放射学光束的能量和剂量范围内，对一些已知类型的热释光剂量计（TLD）——三种CaSO(4):Dy颗粒、烧结Al(2)O(3)颗粒、LiF:Mg,Ti（哈肖TLD - 100）、CaF(2):Dy（哈肖TLD - 200）和CaF(2):Mn（哈肖TLD - 400）——进行直接性能比较。评估了几个剂量学特性，如再现性、灵敏度、校准曲线、较低剂量限值和能量依赖性。
