As part of "Long-Term Assessment of Transport of Radioactive Contaminant in the Environment of Fukushima" (F-TRACE project), JAEA have researched to expect the transportation of radioactive caesium from contaminated mountain forests to estuary and coast through dam, pond, river etc. based on survey data in Fukushima prefecture, and to implement technical information and remedial measures to prevent contamination of decontaminated areas and domestic water supply. In the forest area, it is considered that radioactive caesium existed in the tree canopies move to the surface of the ground through litter fall, through fall and stem flow. In this study, we report properties and distribution of radioactive caesium of the surface soils at stem base of Japanese cedar in the Ogi district of Kawauchi-mura to know the influence of the stem flow on soil.
