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.

The debris, which is approximately 1 cubic meter in size, was transferred to a building on the south side of the Fukushima Daiichi complex for temporary storage, until it can be transferred to a solid waste storage site in the future.
