To deliver the desired absorbed dose to the tumor and save the neighboring healthy tissue the sources of errors in the assessment of the therapeutic dose should be minimized. In the current work, 64 of LiF dosimeters (TLD-700 and TLD-600) were used. The sensitivity factor of each dosimeter with its percentage deviations σ% was calculated and the samples which have σ (>2) more than the desired uncertainty were excluded. Three protocols for the treatments of the TLD data were applied. Firstly, by subtraction the zero dose reading; secondly, by eliminating the high-temperature range of the glow curve, and thirdly, by taking the maximum height of the fifth dosimetric peak (P5). Improvement in the linearity dose response range used in therapeutic doses was achieved using the second method. The suggested proposal succeeded in reducing the linear measurements region in radiotherapy to 1.1 mGy.

热释光剂量计在放射治疗中剂量范围的改进

为了向肿瘤输送所需的吸收剂量并保护邻近的健康组织，应尽量减少治疗剂量评估中的错误来源。在目前的工作中，使用了 64 个 LiF 剂量计（TLD-700 和 TLD-600）。计算了每个剂量计的灵敏度因子及其百分比偏差 σ%，并排除了 σ (>2) 超过所需不确定度的样品。应用了三种处理 TLD 数据的协议。首先，通过减去零剂量读数；第二，通过消除辉光曲线的高温范围，第三，通过取第五个剂量测定峰（P5）的最大高度。使用第二种方法实现了用于治疗剂量的线性剂量响应范围的改进。
