Summary

Radioactive materials emitted from the Fukushima Daiichi Nuclear Power Station (FDNPS) were deposited on soils and trees in forested areas, agricultural land and urban areas. It is expected that the radioactively polluted soils and radioactive materials would spread through erosion of soils from mountains and rivers. In this chapter, we first examine the behaviour of radioactive materials deposited on the ground in upcountry districts. Second, we discuss the movement of radioactive materials from various types of flatlands and forests in mountainous areas based on their chemical forms in soils and on trees. Finally, we report on the accumulation and transfer of radioactive materials to vegetation such as trees.
