B11K:
Biogeoscience Processes Governing Radioisotope Transfers after Fukushima and Other Nuclear Accidents I


Session ID#: 8880

Session Description:
The Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident resulted in the largest release of radioactive material since Chernobyl. Characterizing post-accident radioisotope transfers is important for managing potential radiation exposure. Radioisotope transfers following nuclear accidents occur over a wide range of spatial and temporal scales: from forest and soil environments; to hillslope and riverine systems; up to oceanic and atmospheric scales. As a variety of biogeoscience processes govern these radioisotope transfers, often multi-disciplinary approaches are required to comprehensively quantify radioisotope dynamics. Further, radioisotopes from Fukushima and other nuclear accidents provide a unique opportunity to increase our understanding of material transfers. The goal of this session is to illustrate novel approaches across a range of disciplines and scales characterizing radioisotope transfers. Accordingly, we welcome all contributions advancing our understanding of transfers following nuclear accidents.
