“Japan suspended operations to prevent a stricken nuclear plant from melting down Wednesday after a surge in radiation made it too dangerous for workers to remain at the facility.
Chief Cabinet Secretary Yukio Edano said work on dousing reactors with water was disrupted by the need to withdraw.
The level of radiation at the plant surged to 1,000 millisieverts early Wednesday before coming down to 800-600 millisieverts. Still, that was far more than the average
‘So the workers cannot carry out even minimal work at the plant now,’ Edano said. ‘Because of the radiation risk, we are on standby.'”
