Challenges for Fukushima environmental restoration; JAEA's perspective

Iijima, Kazuki  ; Miyahara, Kaname  

This presentation provides a concise overview of knowledge and experience gained from the activities for environmental remediation after the Fukushima Daiichi (1F) accident to establish the technical basis for strategic, off-site response to nuclear incidents. It reflects JAEA's key role in the research associated with both remediation of contaminated areas and also the natural contamination migration processes in non-remediated areas. This presentation also provides a perspective on the future actions required to remediate all areas outside the 1F site, where continuing R&D is essential to facilitate return of residents to the most contaminated zones from the standpoint of environmental chemistry and radiochemistry with special emphasis on associated waste management.
