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Caso_4(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。
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 20 mrad/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-LET particles are studied by LiF (Mg, Ti) and CaSO4 (Tm) detectors and glow curve deconvolution.
