Engineering researchers at the University of Michigan have released a prototype of the “Polaris-H”, a radiation detector that not only works faster than its predecessors, but is also less expensive. The detector is actually a camera that sets a gamma-ray map over the view of the room. This lets users see radiation, at least on the screen. Unlike older versions of radiation detectors, this device can function at room temperature and be left alone to pick up information. The data on radiation is then stored to a USB drive, which can be inserted into a computer to analyze later. Previous methods of collecting radiation data could take weeks, but the “Polaris-H” can get the job done in half an hour. This commercialized innovation is already at work at NASA and the Department of Defense, besides, of course, nuclear power plants.
