Washington Post, Oct. 22, 2013: [...] Japan’s effort to clean up what remains of the complex is turning into another kind of disaster. [...] 400 tons of toxic groundwater is flowing daily into the Pacific Ocean [...] the flow of radioactive water amounts to a slow-burning environmental disaster with implications for Japan’s wildlife and its food chain. [...] The coastal Fukushima plant is on an old riverbed [...] rainfall from across the region would funnel toward the plant [...] Both the government and Tepco say the ocean contamination is confined mostly to a man-made harbor around the plant. But some scientists say that assurance plays down significant long-term concerns about marine life and the food chain. Cesium levels are still hundreds of times the pre-accident norm in areas beyond the harbor, said Ken Buesseler, a senior scientist with the Woods Hole Oceanographic Institution who has monitored waters around the nuclear plant, most recently last month. [...] “It’s a serious concern for internal doses. (Radionuclides) are now on the seafloor and could stay in the food chain for years, if not decades.” [...]
NHK WORLD, Oct. 21, 2013: [Tepco] has announced plans to monitor offshore radiation around the clock [...] many experts have been calling for 24-hour monitoring to allow faster responses to unexpected leaks and provide a clearer idea of how much water has escaped. [...] The nuclear regulators have proposed expanding the offshore monitoring from the current 300 kilometers to between 1,000 and 3,000 kilometers. [...] the agency will ask the operators of oceangoing vessels to collect data for northern Pacific Rim countries that are worried about radioactive leaks.
NHK Newsline, Oct. 21, 2013: “Nuclear regulators proposed increasing the distance they’re monitoring from 300 kilometers to up to 3,000 kilometers”
