TOKYO, March 31 (Reuters) - The Japanese government must consider whether to expand the evacuation zone around the earthquake-wrecked Fukushima Daiichi nuclear plant, the country's nuclear safety agency said on Thursday.
The U.N. nuclear watchdog has suggested that Japan consider widening the zone.
Currently, those within a 20-km (12-mile) radius from the plant have been ordered to leave. The government has encouraged those living in a 20-30 km ring to leave but has not ordered them to do so, advising only that they remain indoors.
