| 内容記述 | The activities of anthropogenic and natural occurring radionuclides in marine environment have been monitored near the nuclear facilities. These data has been used to construct a dynamic model in the ocean. However, some radionuclides have been used as a tool to elucidate particle dynamics on time scales ranging from day to year in the ocean. Because the concentrations of radionuclides and particles are very low in the ocean, it is difficult to concentrate and fractionate the particulate matters with the filtration systems in seawater. The large volume in situ filtration and concentration system (LV-FiCS) was developed to collect various forms of trace radionuclides and particles in seawater. The LV-FiCS has been operated during several cruises in the coastal waters off Japan, and four to eleven m3 of seawaters were filtered through different kinds of filters and then pass through the adsorbents to concentrate radionuclides simultaneously. We report the vertical profiles of plutonium and thorium with the size-fractionated method and those of cesium and technetium. These results suggested the behavior of these nuclides in the ocean. | |||||
