Toshiba Corporation developed the Portable Gamma Camera, which enables to easily find radiation hotspots. The company will have a field test of the camera in collaboration with Fukushima City within December 2011 and begin to promote its use to the central bureaucracy and local governments in Japan in early 2012. The Portable Gamma Camera combines gamma ray data measured by its radiation sensor and an image taken by its camcorder with a signal processing device. And it shows the amount of radiation in different colors. It uses red color for high amounts of radiation and yellow, green and blue colors for lower radiation levels. The amount of radiation is not homogeneous in each area, and there are hotspots, where radiation level is locally high.

And it takes time to find hotspots by using radiation meters. The camera measures 380 x 110 x 241mm and weighs 9.8kg. It is equipped with 128 semiconductor detection elements as radiation sensors. Its view angle is 60°. It can be powered by either an AC100V power source or batteries. When it is powered by batteries, it can be operated for three hours.
