An intensive field monitoring campaign has been started, immediately after the Fukushima NPP accident including detailed monitoring site in upstream (Yamakiya site), and 30 monitoring sites in downstream river sites. In this presentation, I will present the summary of four years environmental transfer studies after the Fukushima NPP accident. The detailed monitoring of activity concentration of radiocesium and their flux, which can be applicable for the fate and flux of the radionuclide transfer in humid temperate environment. We also found that land use controls most of the transport and then fate of Cs-137 in terrestrial environment.
