A handheld radiation camera developed by University of Michigan engineering researchers offers nuclear plant operators a faster way to find potentially dangerous hot spots and leaky fuel rods.
The new 'Polaris-H' detector lays a gamma-ray map over an image of a room, pinpointing radiation sources with unprecedented precision. At least four U.S. nuclear power plants are using versions of the camera, which is now available commercially through the U-M spinoff company H3D.
"This technology enables people to 'see' radiation," said Zhong He, a professor of nuclear engineering and radiological sciences at U-M and CEO of H3D. "This should enable the early detection of leaks by locating abnormal radiation, a much better understanding of radiation sources to protect workers, and it could be a tool for the cleanup effort of nuclear waste and fallout, such as in Fukushima in Japan."
