TOKYO - The consistently high levels of radiation found in the sea outside Japan's tsunami-damaged nuclear plant complex may mean that radiation is leaking out continuously, Japan's nuclear watchdog said on Thursday.
He added that regulators and engineers did not know where the leaks may be.
Radioactive Iodine in seawater near the drains running from the Fukushima Daiichi nuclear plant was 4,385 times more than the legal limit, the highest recorded since the crisis was triggered by an earthquake and tsunami on March 11.
