A team at the University of Washington rigged up a detection system as soon as it became clear the Japanese reactors were damaged. Unlike some agencies, they have shared their full results with the public — including the newest measurements that show levels are now a tenth of what they were on March 20, when concentrations of radioactive material peaked in Seattle...(more)
