Revolutionary nuclear radiation detector hits the market

ANN ARBOR — 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. (more…)

ANN ARBOR, Mich.— While exposed spent fuel rods at the failing nuclear reactors in Japan pose new threats, the worst-case scenario would still be unlikely to expose the public to catastrophic amounts of radiation, says a University of Michigan nuclear engineering professor who is an expert on this particular kind of reactor.

“For the public, I don’t believe it would be much higher than two additional chest x-rays,” said John Lee, a professor in the Department of Nuclear Engineering and Radiological Sciences, citing the results of the Three Mile Island accident. (more…)
