| Outline of Final Research Achievements |
To predict the future distribution of fallout Cs-137 released from Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, we investigated distribution of global fallout Cs-137 that had deposited to forest soils all over Japan during 1950-60s. Larger depositions of global fallout were observed at the Sea of Japan side along Tohoku to Hokuriku Districts because of large winter precipitation and aerological conditions. We revealed that most part of deposited global fallout remained at the initially deposited place after fifty years by comparing our estimation of radiation inventory with the meteorological observation. We anticipate that fallout Cs-137 from FDNPP will also remain over a long period in the forests.
