Thermoluminescent dosimeters have been used to perform dosimetry measurements for the widely used Ir-192 microSelectron-HDR source with an improved polystyrene phantom. Radial dose functions and anisotropy functions, main parameters of 2D dose-rate formalism from the TG-43U1 protocol, have been obtained experimentally. Measurement results are compared with that of the Monte Carlo calculations reported, and no difference has been found between them.
热释光剂量计已被用于使用改进的聚苯乙烯模体对广泛使用的Ir-192微型Selectron-HDR源进行剂量测定测量。已通过实验获得了径向剂量函数和各向异性函数，它们是TG-43U1协议中二维剂量率形式的主要参数。将测量结果与所报道的蒙特卡罗计算结果进行了比较，未发现它们之间存在差异。
