Development and Current Status of a Carborne Gamma-Ray Survey System, Kurama-II

A carborne gamma-ray survey system, named KURAMA (Kyoto University RAdiation MApping system), was developed as a response to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant in 2011. A CompactRIO-based system KURAMA-II has been developed as the successor of KURAMA, and served for various activities on the radiation monitoring in Eastern Japan. We continue developing KURAMA-II as a tool not only for the current monitoring activities, but also for the immediate responses in nuclear incidents in future. The current status and on-going developments of KURAMA-II will be introduced along with the recent status of the east Japan.
