本発表では、福島県川俣町及び浪江町の森林を対象として、福島原子力発電所事故から8年間の森林環境での放射性セシウムの移行状況の調査結果について報告するとともに、雨水や落葉等に伴う詳細な移行プロセスと放射性セシウム濃度の長期変化傾向の形成について考察した。

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.
