    Radionuclides in Seawater and Sediments From Near-Shore Area of Shenzhen

    • In this study, seawater and sediment were collected from the near-shore area of Shenzhen and analyzed for radionuclides. The results indicate that, the radioactive concentration of 226Ra, 232Th, 40K and 137Cs in the seawater are in the range of 12.8-42.6 Bq/m3 (averaged (24.2±8.6) Bq/m3), 3.2-15.6 Bq/m3 (averaged (8.8±3.6) Bq/m3), 529.7-974.1 Bq/m3 (averaged (786.4±158.4) Bq/m3) and 1.7-3.7 Bq/m3 (averaged (2.6±0.7) Bq/m3), respectively. In the sediment, the specific activity are in the range of 17.9-35.0 Bq/kg (averaged (26.5±5.4) Bq/kg), 32.9-59.8 Bq/kg (averaged (43.2±9.1) Bq/kg), 326.2-415.3 Bq/kg (averaged (364.2±32.4) Bq/kg) and 0.9-3.5 Bq/kg (averaged (1.8±0.8) Bq/kg), respectively. The radioactive concentrations of 110Agm in the seawater and sediment are all below the detection limit. The radioactive concentration of these radionuclides fall in the range of those obtained from other near-shore areas of China, and no abnormal radioactivity nuclide level are observed in seawater and sediment samples from Daya Bay.
