tritiated water

Japan is planning to release tons of water from the Fukushima nuclear site into the Pacific Ocean – water contaminated with tritium, a radioactive form of hydrogen. This has led to protests by China, South Korea, Russia, and other nations; an outcry from a variety of environmental groups … not to mention seafood lovers concerned about the safety of their sushi. Given these concerns, it seems reasonable to dig into the subject a tad to see how serious a concern this is.
