摘要: 本文介绍了实验卫星中空间辐射剂量信息的热释光分析方法。应用LiF(Mg, Cu, P)探测器及程序加热方法, 分析测定了几次实验卫星中空间辐射日平均剂量, 均在20mrad/d以下。应用LiF(Mg, Ti)和CaSO4(Tm)探测器及发光曲线反卷积分析方法, 研究了探测器本底荧光与低温峰影响的减除技术和高LET粒子造成的微观剂量分布不均匀情况。Abstract: The thermoluminescence analysis method of space radiation dose information aboard the experiment satellites are described in this paper. Using LiF (Mg, Cu, P) detectors and pro-grammed-heating, the space radiation daily dose in experiment satellites were measured. It is lower than 20mrad/day, the background luminescence of detectors and way that reduce influence of low-temperature peak and inhomogeneity of irregularities of dos distribution formed by high-LETparticles are studied by LiF (Mg, Ti) and CaSO4 (Tm) detectors and glow curve deconvolution.
