（１）Measurement from the Sky

Abstract

Radioactive materials were diffused in the environment by the accident of the Fukushima Daiichi Nuclear Power Plant, TEPCO. Radiation monitoring from the sky is effective to find the contaminated areas quickly in Fukushima Prefecture, where 70% is occupied by the forests. In this report, it is given an outline about a monitoring technology from the sky using unmanned aerial vehicles and a new measuring technique under development as well as the aerial monitoring using the manned helicopter.
