Radiation levels in sea water near Japan's damaged Fukushima nuclear plant have reached more than 3,000 times the legal limit, officials said, as efforts continue to bring the country's nuclear crisis under control.
Japan's nuclear safety agency said on Wednesday that water near the crippled plant's No. 1 reactor contained radioactive iodine at 3,355 times the legal limit.
Officials said they did not know what caused the radiation level to rise.
"The figures are rising further. We need to find out as quickly as possible the causes and to stop them from rising any higher," Hidehiko Nishiyama, the agency's deputy director-general, told a news conference.
But he also played down the danger, saying residents had been evacuated from the area and no fishing was taking place.
"Iodine 131 has a half-life of eight days, and even considering its concentration in marine life, it will have deteriorated considerably by the time it reaches people."
