Abstract
Radiocesium dynamics in forests contaminated after Fukushima Daiichi Nuclear Power Plant (FDNPP) accident was studied during the early phase (ca. until 5 years). Despite the difference in climate and forest types, the major dynamics of radiocesium followed the case of Chernobyl Nuclear Power Plant (ChNPP). Because there were rather few observations of deformity of organisms, the radiocesium dynamics in forest ecosystem was organized by ecological interaction based on physicochemical cycling of elements in forest ecosystem. Biological differences of radiocesium translocation within plant bodies in canopy tree species were clearly shown by the detailed studies on physiology and ecology of trees, especially Japanese red cedar (Cryptomeria japonica). Coppice oak for edible mushroom cultivation was intensively damaged by a combination of strong absorption of radiocesium to bark and higher transfer factor of radiocesium by mushroom. Rehabilitation of contaminated forest ecosystem for human use was discussed.
