| 目的 调查分析全国首台AP1000核电机组安装后周围生活饮用水中90Sr和137Cs及食品中137Cs放射性水平及变化。方法 2012—2019年，选取全国首台AP1000核电机组所在的三门核电站周围的4个生活饮用水监测点，分别在丰水期和枯水期采集并测定90Sr和137Cs放射性活度浓度；采集当地产大米、包菜、鲫鱼和鲻鱼，测定分析137Cs放射性活度浓度。结果 2012—2019年，生活饮用水中90Sr和137Cs放射性活度浓度范围分别为1.2~9.8、0.2~8.1 mBq/L；食品中137Cs放射性活度浓度为1.1×10-2~2.8×10-1 Bq/kg，小于《食品中放射性物质限制浓度标准》（GB 14882-94）限制浓度。结论 全国首台AP1000核电机组安装后周围生活饮用水中90Sr和137Cs及食品中137Cs放射性水平平稳，调查数据显示未发现对环境带来影响。 |

| Objective To investigate and analyze the radioactivity levels of 90Sr and 137Cs in drinking water and 137Cs in food after the installation of the first AP1000 nuclear power unit in China. Methods From 2012 to 2019, four drinking water monitoring points around AP1000 nuclear power unit located at Sanmen nuclear power plant site were collected during the wet season and dry season, 90Sr and 137Cs and radioactivity concentrations were determined in drinking water. Local rice, cabbage, crucian and mullet were collected to determine the radioactivity concentration of 137Cs. Results From 2012 to 2019, the radioactivity concentrations of 90Sr and 137Cs in drinking water were 1.2-9.8 mBq/L and 0.2-8.1 mBq/L, respectively. The radioactivity concentration of 137Cs in food were 1.1×10-2-2.8×10-1 Bq/kg, lower than the limits specified in the Limited concentrations of radioactive materials in foods (GB 14882-94). Conclusions After the installation of the first AP1000 nuclear power unit in China, the radioactivity levels of 90Sr and 137Cs in drinking water and 137Cs in foods are stable, without environmental impact identified. |
