Tritium (H) is one of the most critical nuclides for environmental monitoring, yet it is challenging to measure. Its high natural mobility and its potential to enter the human body through the food chain underscore the importance of not overlooking the radiation safety risks associated with tritium. The need for the online measurement of tritium at low concentrations is becoming increasingly apparent. This review examines the two principal stages of current measurement methodologies: sample preparation and radiation signal detection. It provides a summary of the tritium sample preparation and detection techniques, highlighting advances in the research with potential applications in online monitoring. The review concludes with an analysis of the issues inherent in the current techniques and offers perspectives on possible technological enhancements and future trajectories for the development of online monitoring systems for trace tritium levels.
氚（H）是环境监测中最关键的核素之一，但测量起来具有挑战性。其高自然迁移率以及通过食物链进入人体的可能性凸显了不忽视与氚相关的辐射安全风险的重要性。对低浓度氚进行在线测量的需求日益明显。本综述考察了当前测量方法的两个主要阶段：样品制备和辐射信号检测。它总结了氚样品制备和检测技术，突出了研究进展及其在在线监测中的潜在应用。综述最后分析了当前技术中固有的问题，并就痕量氚水平在线监测系统的可能技术改进和未来发展轨迹提出了观点。
