摘　　要：介绍了田湾核电站附近海域海水中^(137)Cs的监测方案以及质量保证措施,给出了电站投运后^(137)Cs通过气态途径与液态途径的排放量以及2004—2015年的监测结果,并将监测结果与本底调查结果及海水水质标准规定的数值进行了比较。监测结果表明,电站运行前后海水中^(137)Cs活度浓度与本底调查结果有明显差异;监测结果远小于海水水质标准规定的数值。Monitoring program and quality assurance measures of 137^Cs activity concentrations in the seawater near the Tianwan nuclear power station were described,and emission amounts of 137^Cs through gaseous and liquid pathways since commercial operation and monitoring results in 2004—2015 were given. The monitoring results were compared with background survey results and the reference value for seawater quality. It showed obvious difference in 137^Cs activity concentrations between monitoring results and the background survey results,and the monitoring results were far below the reference value for the seawater quality standard.
