Radiation Monitoring after the Fukushima Dai-Ichi Reactor Incident and Its Metadata Archiving

Abstract

Due to the severe accidents at the Fukushima Dai­Ichi nuclear power plant caused by the large earthquake on March 11, 2011, huge amounts of radioactivity emitted from the plant contaminated the environment. After the incident, many efforts by government, companies and citizens have been made for radiation monitoring.

While various data are available on the internet, an effort was also made to create a metadata­base in the in the form of a whole data catalogue that would archive all available data. In this article, I report the status of various radiation monitoring and data archiving effort since the Fukushima nuclear accident. Also discussed is theideaofametadata­basetoarchiveall the data, including data sets created by citizens, which are scattered around on internet sites.
