Six more workers at the Fukushima No.1 nuclear plant may have exceeded the radiation exposure limit, bringing the total to eight, the Japanese government said.
Three men are control room operators and five worked to restore power that was knocked out by the earthquake and tsunami on March 11. Tokyo Electric Power Company (TEPCO) said the men would require long-term monitoring.
Soon after the disaster, the government raised the radiation limit for men to 250 millisieverts from the standard 100 millisieverts so workers could tackle the emergency.

TEPCO has admitted that workers in the earliest moments of the crisis did not wear masks and lacked dosimeters to monitor their radiation exposure.
