The accident of the Fukushima Daiichi Nuclear Power Station (hereinafter referred to 1F), Tokyo Electric Power Company Holdings, Inc. occurred due to the Great East Japan Earthquake, Sanriku offshore earthquake, of 9.0 magnitude and the accompanying tsunami. As a result, large amount of radioactive materials was released into the environment. Under these circumstances, JAEA has been conducting Long-term Environmental Dynamics Research concerning radioactive materials released in environment, especially migration behavior of radioactive cesium since November 2012. This report is a summary of the research results that have been obtained in environmental dynamics research conducted by JAEA in Fukushima Prefecture.

The Fukushima Daiichi Nuclear Power Station (FDNPS) Accident caused release of various radionuclides into the environment. About 70% of radioactive cesium deposited on forests in Fukushima prefecture far from living sphere so that they are not planned to be specifically decontaminated, meaning that radioactive cesium will remain in the forests in future. Japan Atomic Energy Agency (JAEA) has carried out the F-TRACE project in which the transport behavior of radioactive cesium from forests to the ocean via river systems in Fukushima Prefecture was investigated. In this study, understandings of transport behavior of radioactive cesium in the environment obtained in field activities and simulation were overviewed.
