Highly radioactive debris recovered from atop crippled Fukushima Daiichi reactor

Workers at Fukushima Daiichi were working this week to remove rubble from atop the crippled Fukushima Daiichi Unit 3 reactor building with remote-controlled cranes, when they discovered the radiation dose from a piece of debris they removed from the 5th floor of the reactor building was highly radioactive and releasing a dose rate over 540 millisieverts per hour.  The maximum allowable exposure for radiation workers in the U.S. is 50 millisieverts per year.
