Comparison of Germanium Semiconductor Detector and NaI Scintillation Detector in Brown Rice Analysis Relative to Accident of Tokyo Electric Power Company, Fukushima Daiichi Nuclear Power Station

Abstract

The nuclear accident of Fukushima Daiichi Nuclear Power Station scattered radioactive cesium, following the Tohoku earthquake on March 11, 2011. In the present work, alternative radioactivity data obtained from NaI(Tl) scintillation analyzers and a Ge semi-conductor detector were compared and evaluated with respect to the correlation of those values, the accuracies and the sensitivities using as an actual agricultural product, brown rice which was contaminated by Fukushima Daiichi Nuclear Power Station accident.
