TRANSPORT OF RADIONUCLIDES ALONG MARINE FOODCHAIN

TRANSPORT OF RADIONUCLIDES ALONG MARINE FOODCHAIN 1 first-author 1 1 Department of Physics and Materials Science, City University of Hong Kong Department of Physics and Materials Science, City University of Hong Kong A compartment model is employed to calculate the radionuclide concentrations in the ocean currents for a nuclear accient scenario where the long-lived 137 Cs is totally discharged into the sea. The radionuclide concentrations in both the waters of Daya Bay and the adjacent South China Sea are considered. Using the concentration factors for the marine organisms: fish, crustacea and mollusca, their radionuclide concentrations are also estimated. In this way, the whole body radiation doses received by an individual due to ingestion of marine organisms from the Daya Bay and the South China Sea are calculated.
