TOKYO Radiation levels have risen above the safety limit around Tokyo Electric Power Co's (TEPCO) nuclear plant hit by a massive earthquake and the company has informed the government of an "emergency situation," Kyodo agency reported on Sunday.
It did not mean an immediate threat to human health, the company said.
The company said earlier that it had started releasing steam from a reactor at the plant. A similar rise in radiation levels occurred after the company released radioactive steam from another reactor to let go of pressure. Then again the company was obliged to inform the government of an "emergency situation."
