The 137Cs concentrations of suspended sediment were 2.4–49 kBq/kg. The 137Cs concentrations of coarse organic matter were 0.85–14 kBq/kg. The annual proportions of contribution of 137Cs discharge by suspended sediment were 96–99%. The total annual 137Cs discharge from the catchment was 0.02–0.3% of the deposition.
