Japanese ordered indoors in radiation leak crisis
Tokyo also reported slightly elevated radiation levels but officials said the increase was too small to threaten anyone in the capital.
In a nationally televised statement, Prime Minister Naoto Kan said radiation has spread from four reactors of the Fukushima Dai-ichi nuclear plant in Fukushima province, one of the hardest-hit in Friday's 9.0-magnitude earthquake and the ensuing tsunami that has killed more than 10,000 people.
"The level seems very high, and there is still a very high risk of more radiation coming out," Kan said. "We are making utmost efforts to prevent further explosions and radiation leaks."
This is the worst nuclear crisis Japan has faced since the atomic bombing of Hiroshima and Nagasaki during World War II. It is also the first time that such a grave nuclear threat has been raised in the world since a nuclear power plant in Chernobyl, Ukraine exploded in 1986.
Kan warned there are dangers of more leaks and told people living within 19 miles (30 kilometers) of the Fukushima Dai-ichi complex to stay indoors to avoid radiation sickness. Some 70,000 people had already been evacuated from a 12-mile (20-kilometer) radius and 140,000 remain in the zone for which the new warning was issued.
Three reactors at the power plant were in critical condition after Friday's quake, losing their ability to cool down and releasing some radiation. A fourth reactor that was unoperational caught fire on Tuesday and more radiation was released, Chief Cabinet Secretary Yukio Edano said, China Daily reports.
