Stabilization work at Fukushima Daiichi nuclear plant has been temporarily halted, once again, because of high radiation levels.

Reactor 3 began emitting levels above 100 millisieverts per hour.  The government raised the safe limit from 100 to 250 millisieverts per hour, but workers at the damaged nuke plant refused to implement the higher limit.

Tokyo Electric Power Company sent nine workers into Reactor 3 on 10 June 2011.  TEPCo said they are trying to limit workers to just 9 millisieverts per hour.  After only 20 minutes the radiation levels far exceeded the original 100 millisieverts limit!

High radiation levels have made stabilization work almost impossible.  TEPCo has acknowledged that it will take much longer to get the plant under control.

Two workers have tested positive for as much as 678 millisieverts of radiation.  The National Institute of Radiological Sciences confirmed the exposure.  The two men were in the control rooms of reactors 3 & 4, when Reactor 1 blew up on 12 March 2011.  A third man is undergoing testing.
