Camera detects radioactive hotspots


Using radiation meters to map out radioactive hotspots is a time consuming process. To assist the cleanup efforts around Fukushima City, Japan, Toshiba has developed a portable video camera that provides real-time visualisations of where those dangerous hotspots might be.

By combining a camcorder with a gamma ray detector, the unit can display real-time overlays indicating radiation levels using a red (dangerous) to blue (less dangerous) color scale.

The camera will be field tested in and around the damaged Fukushima nuclear power plant in December 2011. Toshiba will promote its use to local governments of Japan in early 2012 so the unit can be used across the country to determine how far the leaks may have spread.
