Radiation off Japan's shores not harmful for sealife

Radioactivity from Japan's power plant disaster last March has been detected as far as 400 miles offshore in the Pacific Ocean.

Scientists say ocean water readings showed up to 1,000 times the prior levels of Cesium-137 leaked from the Fukushima nuclear power plant, but they also say the new readings are far below levels considered harmful to marine mammals and people who eat seafood.

The information was released Tuesday at the Ocean Sciences meeting in Salt Lake City. The data was measured from water samples taken three months after the deadly Japanese earthquake and tsunami last March.
