Japan nuclear crisis: Seawater radioactivity 'rises'

Seawater near Japan's crippled nuclear reactors is said to have a much higher level of radioactive iodine than previously reported.

Water near the Fukushima Daiichi plant's reactor 1 contained radioactive iodine at 3,355 times the legal limit, a government agency said.

Earlier samples had been put at 1,850 times the legal limit.

But an official said the iodine would have deteriorated considerably by the time it reached people.
