Archive Soil Samples Collected in Fukushima Prefecture and Surrounding Areas after TEPCO Fukushima Daiichi Nuclear Power Plant Accident and Construction of Archive Soil Database System

Archive Soil Samples Collected in Fukushima Prefecture and Surrounding Areas after TEPCO Fukushima Daiichi Nuclear Power Plant Accident and Construction of Archive Soil Database System Takahiro Tatsuno1, †, Aya Inada1, 2 and Hirofumi Tsukada1: 1 Institute of Environmental Radioactivity, Fukushima University, 2 Faculty of Wellness Studies, Kwassui Women’s University, † t.tatsuno@ier.fukushima-u.ac.jp Institute of Environmental Radioactivity (IER) at Fukushima University stores approximately 18,000 soil samples received from the Nuclear Regulation Authority, which were collected after the Fukushima Daiichi Nuclear Power Plant accident. The IER is providing a loan service of the archive soil samples and using a database system for the samples. The database system consists of two parts: a data set of the soil samples collected during the first to seventh survey, and a system called ARASO (Assessment Database System for Radioactivity in Soil) which allows us to view and search the soil data from the first survey on a map. ARASO has useful functions, such as, calculating of radioactivity in the specified area and searching for the soil samples according to the research object. It is highly expected that ARASO will promote the utilization of archive soil samples and contribute to the research progress on the radioactivity assessment as well as the fate of radioactive materials in the environment.
