The Japan Times: Tokyo Electric Power Co. said Sunday that 600,000 becquerels per liter of tritium has been detected in groundwater at the crippled Fukushima No. 1 nuclear plant. It’s the first time such a high level of tritium, an isotope of hydrogen, has been measured in the plant’s groundwater, Tepco said [...] A Nuclear Regulation Authority official recently said contaminated groundwater from the plant, which is being fed cooling water from outside, may be seeping into the ocean and that the matter must be addressed carefully because data is limited.
AFP: [...] “From test samples on July 5… we detected a record high 600,000 becquerels per litre” of tritium, 10 times higher than the government guideline of 60,000 becquerels per litre, TEPCO said in a statement. [...] Subsoil water usually flows out to sea, meaning [strontium and tritium] could normally make their way into the ocean, possibly affecting marine life and ultimately impacting humans who eat sea creatures.
