基于光致发光个人剂量监测系统In Light200,对1～100 m Gy辐照剂量范围内的食盐进行光致发光测量,分析了其光致发光信号的线性响应以及信号的稳定性;探究了不同自然光照时间和不同储存时间对食盐光致发光信号的影响。实验结果表明:食盐在1～100 m Gy辐照剂量范围内具有良好的线性响应和信号稳定性;信号在10 min的自然光照时间后降低到本底水平;信号在30 d的储存时间内几乎无衰减;食盐可用作辐射事故中验证重建的剂量材料。

Based on the photoluminescence personal dose monitoring system -InLight200, the salt in the dose range of 1~100 mGy irradiation was measured, analyzing the linear response of the photoluminescence signal and the stability of the signal, and the effects of different natural illumination time and different storage time on Salt Photoluminescence Signal was explored. The experimental results show that the salt has good linear response and signal stability within the irradiation dose range of 1~100 mGy; the signal is reduced to the background level ...
