Japan’s massive quake has a dangerous nuclear fallout: Two power plants struggled to cool their core radioactive material Saturday, a Japanese government official said, while a small leak of atomic material has been reported at one of those facilities. At one plant, radiation levels in the control room reached 1,000 times their normal level. Authorities ordered residents within three kilometers of the Fukushima Daini plant to evacuate as a precaution. Friday’s massive 8.9-magnitude earthquake caused problems at power plants across the country, with a fire being reported a third facility and several plants being shut down. Tokyo has declared a state of atomic power emergency.
