摘要
目的比较LDR-II XA型光致光剂量计与CTLD-J4000型热释光能量鉴别式剂量计的性能。方法通过对两种剂量计的能量响应、剂量响应实验,比较、分析两种剂量计的剂量响应曲线和能量响应曲线。结果制作剂量响应曲线,求线性相关系数R剂光2=0.9999,R剂热2=1,且非线性响应满足国家标准(Ei/Er,0±Ucom,i)×Cr,0/Ci在0.91-1.11的技术要求,制作能量响应曲线,能量响应满足国家标准(Ei/Er,0±Ucom,i)×Cr,0/ Ci在0.71-1.67的技术要求。结论由于本实验室内部兼有两套系统,通过系统间比对可以加强实验室质量控制。同时,以上两种个人剂量计各有优缺点,根据二者特点选择合适剂量计进行日常或应急情况下放射工作人员的个人剂量监测。
Objective To compare the LDR-II XA OSL dosimeter with the CTLD-J4000 TLD dosemeter of the performance.Methods Conduct experiments about energy response and dose response characteristics.Compare and analyze the curves of both the characteristics above.Results Make the curves of energy response and dose response calculate the linearly dependent coeffients:R剂光2=0.9999,R剂热2=1.The technical index(Ei /Er,0±Ucom,i)×Cr,0/ Ci of nonlinear response for dose response is according with the national standard(0.91~1.11)and the technical index(Ei/ Er,0±Ucom,i)×Cr,0/ Ci for energy response is in accordance with the national standard(0.71~1.67).Conclusion We can strengthen quality control through comparison experiment between the two systems.Both dosimeters have advantages and disadvantages,and we can choose the appropriate one according to their characteristics to make routine monitoring or emergency monitoring.
