Radiation from Japan’s Fukushima No. 1 nuclear power plant disaster has been detected 400 miles offshore in the Pacific from where the facility underwent meltdowns last year.

While contamination of the isotope cesium-137 was up to 1,000 times above previous recorded levels, scientists asserted that the new readings are far below the levels that are considered harmful.

Ken Buesseler of the Woods Hole Oceanographic Institution told the biennial Ocean Sciences Meeting that the radiation was not dangerous to either the marine mammals in the contamination zone or to humans who eat seafood.

In a related development, the Tokyo Electric Power Co. says it will spread cement and clay over the seabed near the crippled plant to prevent the further spread of radioactive substances already deposited there.
