More accurate picture of Fukushima radiation with new camera

New Camera Sees Japan’s Radiation Threats Innovation News Daily   30 March 2012  One year after Japan’s nuclear disaster, the invisible threat of radiation still lurks around homes and businesses near the Fukushima Dai-ichi power plant. Now, a new camera based on Japanese space technology has allowed humans to see the radioactive contamination around the nuclear plant’s emergency evacuation zone.

Such camera technology works by detecting radioactive particles that give off gamma rays — the highest-energy form of light in the universe. The Japan Aerospace Exploration Agency (JAXA) originally developed the technology for an upcoming X-ray observation satellite, called ASTRO-H, but successfully adapted the camera to spot Earthly radiation threats  such as Cesium 137 and Cesium 134.

The camera’s wide 180-degree vision showed radioactive particles spread across the ground and  on rooftops of the village in the Fukushima Prefecture during a field test Feb. 11. Its results proved more accurate and capable of capturing a broader snapshot of the
radioactive zone than existing cameras…. http://www.space.com/15113-camera-sees-japan-radiation.html
