| 中文摘要: |
| 本文引出TLD系统的优质因子P=S0/B, 并以文献[1, 2]给出的TLD系统为例, 用最优化实验方法求得目标函数P=f(T、T1、T2, t…)取最小值时相应的一组测读参数, 从而使该系统的应用范圆向低剂量区延伸了一个量级。用这种方法对国产JR-152、FJ-377TLD系统进行的实验效果也很显著, 这种处理方法可推广到其他TLD系统。建议用优质因子作为TLD系统调试的参考指标, 并用于比较不同的TID系统。 |
| 英文摘要: |
| The quality factor P=S0/B of thermoluminescent dosemeter system was deduced in thiB paper.In the case of LiF-HS and JRG Ⅲ TLD system, when minimal values in the objective function P=f(T, T1, T2…)were chosen, a set of relevant measure parameters was obtained in the experimental method of optimization. This made the applicability of the system extend to low-dose level for aiq dcder of magnitude.When this method was applied to JR-152, FJ-337 TLD systemspthe results were also obviOUS.It can be used.In any other TLD systems.The quality fadtot can be used as a criterion for checking TLD system and for comparing different TLD systems. |
