"Operators at the Fukushima Daiichi plant's Unit 1 scrambled ferociously to tamp down heat and pressure inside the reactor after the 8.9 magnitude quake and the tsunami that followed cut off electricity to the site and disabled emergency generators, knocking out the main cooling system.

Some 3,000 people within two miles of the plant were urged to leave their homes, but the evacuation zone was more than tripled to 6.2 miles after authorities detected eight times the normal radiation levels outside the facility and 1,000 times normal inside Unit 1's control room."
