The operator of a Japanese nuclear power plant where a reactor’s containment building exploded says radiation levels at the unit are within legal limits.
Tokyo Electric Power Co. says radiation levels at Unit 3 of the stricken Fukushima Daiichii plant were 10.65 microsieverts on Monday, significantly under the 500 microsieverts at which a nuclear operator is legally bound to file a report to the government.
There was a hydrogen explosion at the unit earlier in the day.
Officials have been racing to stave off multiple reactor meltdowns after a devastating quake and tsunami incapacitated the Fukushima plant.
More than 180,000 people have evacuated the area, and up to 160 may have been exposed to radiation.
