Radioactivity levels high in the sea off Japan nuclear plant - latimes.com: "Even as engineers tried to pump puddles of radioactive water from the power plant 150 miles north of Tokyo, the nuclear safety agency said tests Friday showed radioactive iodine had spiked 1,250 times higher than normal in the seawater just offshore from the plant.
Officials said iodine 131 levels in seawater 19 miles from the coastal nuclear complex were within acceptable limits established by regulations and the contamination posed little risk to aquatic life.

'Ocean currents will disperse radiation particles and so it will be very diluted by the time it gets consumed by fish and seaweed,' said Hidehiko Nishiyama, a senior official from Japan's Nuclear and Industrial Safety Agency.
Despite that reassurance, the disclosure may well heighten international concern over Japanese seafood exports. Several countries have already banned milk and produce from areas around the Fukushima Daiichi plant, while others have been monitoring Japanese seafood."
