Abstract:
We have developed a dose estimation system integrating assessment methods of radionuclide dispersion in ocean for the case of recycling radiocesium-contaminated soil to coastal reclamation. Radionuclide dispersion in ocean is assessed considering dissolved radionuclide and adsorbed radionuclide on particle by sediment model (OECD/NEA). Time series of Cs-137 dispersion at Fukushima coastal area is assessed by the sediment model and result is almost same with measured value. The major exposure pathways in recycling are estimated by using result of radiocesium dispersion assessment, and internal exposure dose by marine products ingestion is sufficiently lower than external exposure dose of worker.
