Vertical distributions of global fallout Cs-137 and C-14 were investigated in a Japanese forest soil in 2001. Even 38 years after the fallout, Cs-137 was still observed mostly in the uppermost 5 cm. A preferential accumulation of Cs-137 was found in a 1-cm-thick transition layer between organic-rich A and underlying B horizons. This unique observation indicated that Cs-137 migrated through the A horizon at a rate of 0.20 % year(-1) and the transition layer acted as a barrier for Cs-137 migration to deeper layers. The vertical distributions of Cs-137 and C-14 were significantly correlated, suggesting a coupled downward migration of Cs-137 and organic matter on a time scale of decades, along the same physical pathways.
