Radiation levels have fallen at Japan's earthquake-stricken Fukushima Daiichi nuclear plant, the government says.
The announcement was made after a fire was extinguished at the plant.
The government had earlier warned that radiation leaks from the plant had reached harmful levels.
Weather reports indicate winds are dispersing radiation from the plant to the east, over the Pacific Ocean, but the government has ordered people living within 20km (12 miles) to leave.
Officials have warned people within 20-30km of the plant to either leave the area or stay indoors.
Japan has also announced a 30-km no-fly zone around the plant to prevent planes spreading the radiation further afield.
