| 目的 调查三门核电站周围环境辐射累积剂量水平及周边海水海产品中137Cs含量。方法 2015—2019年，在三门县境内设置60个监测点，监测环境辐射累积剂量；以核电厂排水口为起点，5 km范围内设置6个监测点采集海水，测定海水中137Cs；采集核电站周围海域的当地居民经常食用的紫菜、带鱼、鲻鱼，测定海产品中137Cs。结果 2015—2019年，核电站周围环境辐射累积剂量范围为0.321~0.411 mSv；5 km范围内海水中137Cs活度浓度范围为0.579~2.119 mBq/L；附近海域紫菜、带鱼、鲻鱼中137Cs的活度浓度范围分别为0.498~0.672、0.399~0.493、0.267~0.371 Bq/kg，均低于《食品中放射性物质限制浓度标准》（GB 14882-94）指导值。结论 三门核电站周围环境辐射累积剂量及周边海水海产品中137Cs的浓度处于本底水平。 |

| Objective To investigate the cumulative dose level arising from environmental radiation and the concentration level of 137Cs in seawater and seafood around Sanmen nuclear power plant. Methods From 2015 to 2019, 60 monitoring sites were set up in Sanmen county to monitor the cumulative dose from environmental radiation. Starting from the outlet of the nuclear power plant, a total of 6 monitoring points were set within 5 km to determine 137Cs concentration in seawater. Nori, hairtail and mullet around the nuclear power plant were collected to determine 137Cs concentration in seafood. ResultsFrom 2015 to 2019,the cumulative dose from environmental radiation were 0.321-0.411 mSv.The concentrations of 137Cs were 0.579-2.119 mBq/L in seawater around the nuclear power plant within 5 km;0.498-0.672 in nori, 0.399-0.493 in hairtail and 0.267-0.371 Bq/kg in mullet, respectively, all lower than the standard values specified in the "Standard for the concentration of radioactive substances in food" (GB 14882-94). Conclusions Around Sanmen nuclear power plant, the cumulative doses from environmental radiation, concentration of 137Cs in seawater and seafood are at the background level. |
