摘　　要：核辐射剂量测量是辐射监测中的一项重要内容。基于光释光(Optically Stimulated Luminescence,OSL)原理搭建掺碳氧化铝(Al_(2)O_(3):C)核辐射剂量测量系统的相关研究迄今已有数十年的历史。该系统将Al_(2)O_(3):C中存储的辐射能量以光信号的形式释放,之后使用光电转换器件将光信号转换为电信号,通过对电信号的采集分析实现辐射剂量的测量,具有灵敏度高、远程探测、保护人员安全、抗电磁干扰等优势。本文介绍了该系统在国防、医疗剂量及个人剂量监测等领域的研究成果,探讨了其未来发展趋势,以期对OSL核辐射剂量测量系统的研究人员提供参考借鉴。Radiation dose measurement is a key part of radiation monitoring.The research on Al_(2)O_(3):C(carbon-doped alumina)nuclear radiation dose measurement systems based on optically stimulated luminescence(OSL)principle has been carried out for several decades.These systems release radiation energy stored in Al_(2)O_(3):C in the form of optical signals,convert optical signals into electrical signals with photoelectric conversion devices and measure the radiation dose by collecting and analyzing the electrical signals.They have the advantages of high sensitivity and remote detection,ensuring the safety of personnel and anti-electromagnetic interference.In this paper,the research findings of these systems in the fields of national defense,medical dose monitoring and personal dose monitoring were introduced,and the development trend of these systems was discussed,aiming to provide reference for researchers of OSL radiation dose measurement systems.
