摘　　要：本工作是基于广东省环境辐射监测中心(以下简称GERC)多年来对广东大亚湾/岭澳核电站周边环境中海水氚活度浓度水平的监测总结。通过对比国家标准,2021年大亚湾/岭澳核电基地周围海水氚的监测结果均在标准范围内。同时,海水中氚活度浓度与天然辐射本底水平相比也可以监测核电站运行对周围环境的实时影响和长期累积趋势影响。海水氚作为GERC对核电站放射性流出物的监测项目之一,其监测结果为核与辐射安全监督提供了科学依据和技术支持。This work is based on the summary of tritium activity concentration in seawater around Guangdong Daya Bay/Ling’ao nuclear power plants monitored by Guangdong Environmental Radiation Monitoring Center(hereinafter referred to as GERC) for many years. By comparing the national standards, the monitoring results of tritium in seawater around Daya Bay/Ling’ao nuclear power base in 2021 are within the standard range.Meanwhile, compared with the natural radiation background level, it can also monitor the real-time impact and long-term cumulative trend impact of nuclear power plant operation on the surrounding environment. As one of the monitoring items of GERC for radioactive effluents from nuclear power plants, the monitoring results of tritium activity concentration in seawater also provide scientific basis and technical support for nuclear and radiation safety supervision.
