SALT LAKE CITY - Radioactive contamination from the Fukushima power plant disaster has been detected as far as almost 400 miles off Japan in the Pacific Ocean, with water showing readings of up to 1,000 times more than prior levels, scientists reported Tuesday.
...The results are for water samples taken in June, about three months after the power plant disaster, Buesseler said. In addition to thousands of water samples, researchers also sampled fish and plankton and found cesium-137 levels well below the legal health limit.
"We're not over the hump" yet in terms of radioactive contamination of the ocean because of continued leakage from the plant, Buesseler said in an interview before Tuesday's talk. He was chief scientist for the cruise that collected the data.
