IUR International Workshop Worldwide harmonization of radioecology networks 18-20 Jun 2014 La Baume Aix en provence Introduction of Institute of Environmental Radioactivity At Fukushima University Kenji NANBA IER at FU
Fukushima Univ. • Smallest among national universities: small number of faculty member for science but widely scattered range of expert fields After the accident • Started projects to measure radiation and map borrowing survey meters as there were no equipment for radiology. • Helped decontamination activities done by JAEA • Studied on agriculture and helped farmers through measurements of radiation and concentration in soil, water and products. • Studied river and lake environment. Held courses of environmental radioactivity in collaboration with other • universities. • Established FURE (Fukushima Future Center for Regional Revitalization) in May 2011 • Requested national government to have an institute for radiological study
IER established in Jul. 2013
Ins tute of Environmental Radioac vity at Fukushima University Research Prospectus Current Needs Among Scien fic Research strategies are chosen by a commi ee of partner research ins tu ons Communi es: ⇒ Projects will take place in a variety of environmental se ngs, including forests, rivers, lakes, and the sea A research base close to observatory sites in Fukushima ⇒ Models for predic ng future radioac ve material transfer within these environments will be established by integra ng collected data The ins tute will be made available for shared use by universi es, ins tutes, and Collec on of data and researchers from Japan and around the world. the crea on of predic ve models related to ○ Inves ga ons, observa ons dynamics of and experiments in Fukushima radionuclides within the ○ Primary processing of environment samples ○ Analysis of samples ○ Archives of early samples ○ Provision of the archives ○ Archives of data and documents ○ Modeling for predic on ○ Convening scien fic mee ngs Rivers and Lakes Long-term dynamics of radionuclides in forests Forest Expected Users （ NIRS, Tsukuba University, Hiroshima University, ● Interna onal Organiza ons Long-term dynamics of radionuclides in rivers and lakes Fukushima University, Nagasaki University, Fukushima IAEA （ Tsukuba University, Fukushima University, NIRS ） Pref.
