In this study we investigated that the influence of Cs-137 concentration in shallow groundwater systems in forest slopes. Our results showed that the average concentration of dissolved Cs-137 in shallow groundwater was 0.64 Bq/L, which was higher than that in surface water (average 0.10 Bq/L). Furthermore, it was also observed that a part of the shallow groundwater on the slope moves toward the river channel at the time of water runoff. This suggests that shallow groundwater may have flowed into the surface water during the outflow and contributed to the increase of Cs-137 in the surface water.
