摘　　要：介绍了 1 994～ 2 0 0 1年大亚湾核电站周围陆地环境的放射性监测结果 ,并与 1 994年核电站运行前的监测结果进行了比较。大亚湾核电站周围陆地环境 γ辐射保持在原本底水平 ;核电站厂区地下水在雨季能测到略高于本底的 3 H;气溶胶、各种生物样、土壤及水样等环境介质中除了检测到与本底水平相当的 13 7Cs、90 Sr外 。The radioactivity level since the operation of Daya Bay Nuclear Power Station was introduced in this paper. Compared with the radioactivity before operation (1994), γ radiation levels around the nuclear power station are kept the same as the background, Sometimes 3H can be measured in groundwater at the nuclear power station. Except 137 Cs, 90 Sr can be measured in aerosol, biological, water and soil environmental samples, other man made radionuclides levels were lower than the minimum detectable limit.
