内容記述To assess the uptake of Cs-137 (137Cs) by freshwater fish, we developed a compartment model for the migration of 137Cs on the catchment scale from forests to river water. We modelled a generic forest catchment with Fukushima-like parameters to ascertain the importance of export pathways of 137Cs from forests to river water for the uptake of 137Cs by freshwater fish. The results suggest that the decreasing trend of 137Cs in river water and freshwater fish was due to combination of the decreasing trend in the forest leaves/needles and litter compartments, and the increasing trend in soil. The 137Cs concentrations within these forest compartments plateau at around ten years after the fallout due to 137Cs circulation in forests reaching an equilibrium state.
