摘　　要：目的评价辽宁红沿河核电站运行后对周边地区食品放射性水平的影响。方法通过对2013年至2020年核电站运行期间周边30 km范围内食品放射性水平的分析,对比核电站运行前后及对照点的放射性水平,评估核电站的运行对当地食品放射性水平的影响。结果当地食品中未发现^(131)I、^(134)Cs、^(60)Co、^(58)Co、^(110)Agm等人工放射性核素,天然放射性核素^(238)U、^(226)Ra、^(232)Th、40K均在正常本底水平,平均值分别为(0.088±0.053)、(0.155±0.178)、(0.314±0.388)和(81.3±18.1)Bq/kg(鲜重)。食品样品中人工放射性^(137)Cs活度浓度平均值为(0.013±0.010)Bq/kg(鲜重)。与对照点及运行前水平比较,放射性核素水平未见增加。结论红沿河核电站的运行未对周边食品放射性水平带来影响。Objective To evaluate the impacts of radioactivity in foods since begining of the operation of the Hongyanhe Nuclear Power Plant(HNPP).Methods The levels of radioactivity in foods collected within 30 km of HNPP from 2013 to 2020 were analyzed by comparison of the control samples and those collected before the operation.The impacts on the operation of the HNPP on foods were evaluated.Results The man-made radionuclides such as ^(131)I、^(134)Cs、^(60)Co、^(58)Co、^(110)Agm were not found in food samples.The nautral radionuclides such as 238U,226Ra,232Th,40K were at the normal levels,with the average levels of(0.088±0.053),(0.155±0.178),(0.314±0.388)and(81.3±18.1)Bq/kg(fresh weight)in foods,respectively.The average levels of man-made nuclide 137Cs in foods were(0.013±0.010)Bq/kg(fresh weight).There was no increase in radionuclide levels compared with the control samples and the samples before the operation.Conclusions The impacts on foods due to the operation of HNPP was not found.
