Camera Can “See” Radiation
JAXA and the JAEA have developed a camera that can spot radiation. Here is a video that shows some examples:
The new camera detects gamma rays emitted by radioactive cesium and other substances, and creates a wide range of images of radioactive contamination.
The total amount of gamma rays emitted by cesium 137 and 134 are captured in six different colors in an image taken with a wide-angle lens, with red representing the highest and yellow second highest radiation levels.
