空间辐射环境的复杂性大大超过在地面的情况,利用不同的探测方法对空间辐射进行准确定量的意义十分重大。热释光探测器(TLD)是探测低LET辐射的主要被动探测器之一,在空间辐射测量中的应用十分广泛。本研究中,利用LiF:Mg,Ti元件开展了γ射线地面标定实验,以期为空间搭载辐射剂量测定的地面标定实验提供基础数据,进而实现对空间辐射剂量的测量。实验中,对元件进行退火处理后,以1 mGyγ射线辐照不同型号的TLD(LiF:Mg,Ti)元件,利
The complexity of space radiation environment greatly exceeds that on the ground. The significance of using different detection methods to accurately quantify space radiation is of great significance. The thermoluminescence detector (TLD) is one of the major passive detectors for detecting low-LET radiation and is widely used in space radiation measurement. In this study, γ-ray ground calibration experiments were carried out using LiF: Mg and Ti devices to provide basic data for ground calibration experiments with space-borne radiation dosimetry, and to achieve the measurement of space radiation dose. In the experiment, different types of TLD (LiF: Mg, Ti) devices were irradiated with 1 mGy γ-ray after the components were annealed
