| Abstract:: |
| 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. |
