High levels of radiation found at Japan nuclear plant, DPA, June 4, 2011:
High levels of radiation were detected at the damaged Fukushima Daiichi nuclear plant in north-eastern Japan, the operator said Saturday.
Tokyo Electric Power Co (TEPCO) said it sent a robot into the building of reactor 1 Friday and detected up to 4,000 millisieverts per hour at the south-east corner of the building. [...]
The operator also said late Friday two workers at the plant were confirmed to have received cumulative doses of radiation far higher than the official limit.
TEPCO, which has been criticized for its lax safety management, said more workers might have been exposed to large radiation doses. [...]
