Fukushima Daiichi Nuclear Power Plant Disaster: Generally Applicable Implications from Measurements of Radioactive Contaminations in Some Areas of Ibaraki and Fukushima

摘要

References(3) Cited-By(2) The March 11 earthquake and tsunami led to the failure of the Fukushima Daiichi Nuclear Power Plant (FDNPP) of Tokyo Electric Power Company (TEPCO), which contaminated wide areas with radioactive substances. Although working for Shujitsu University in Okayama City, the author's home is in Moriya City, Ibaraki Prefecture, 180 km southwest of FDNPP. On several trips to Moriya City from Okayama City, radioactivity of some areas was measured. From July 13 to 18, 2011, the author conducted volunteer activities for screening of the radioactivity of temporary returnees from the evacuation zone area—within a 20 km radius from FDNPP. Making use of this opportunity, the author measured radioactivity in several areas in Fukushima Prefecture. These sporadic and arbitrary measurements yielded generally applicable implications and the results were briefly presented here.
