Japan radiation spike report 'mistaken'

The operators of a stricken Japanese nuclear plant have apologised for a "mistake" in reporting a radiation spike 10 million times above normal.

Tokyo Electric Power Company, which has previously been criticised by officials for its handling of the crisis at the plant, said it got the readings wrong.

Despite the mistake, the radiation spike at reactor 2 was still very high and enough to evacuate workers.
