摘　　要：自从1895年伦琴发现X射线以来,辐射探测技术快速发展,被广泛应用于医疗影像、安检安防、工业无损检测、核安全监测、资源勘探、基础科学和空间科学等诸多领域。从探测材料和工作原理划分,辐射探测器主要可分为气体探测器、闪烁体探测器和半导体探测器。本文从各类射线与半导体材料的相互作用以及半导体探测器工作原理和信号处理过程入手,探讨了不同辐射类型、不同应用需求对半导体辐射探测器的性能要求以及探测器设计要点,并按照元素族序的顺序对半导体材料在辐射探测领域的性能表现和研究进展进行了综述。Since the discovery of X-rays by Röntgen in 1895,radiation detection technology have developed rapidly and have been widely used in many fields such as medical imaging,security inspection,industrial non-destructive testing,nuclear safety monitoring,resource exploration,basic science and space science.In terms of detection materials and working principles,radiation detectors can be divided into gas detectors,scintillator detectors and semiconductor detectors.This article focuses on semiconductor detectors,starting from the interaction between various radiation and semiconductor materials,as well as the working principle and signal processing process of semiconductor detectors,and discusses the performance requirements and main points of detector design of semiconductor radiation detectors in different types of radiation and different application requirements.The performance and research progress of semiconductor materials in the field of radiation detection are reviewed according to the order of element family.
