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.

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.
