Radiation get dumped into the ocean Toxic radioactive substances have once again been detected in groundwater at the crippled Fukushima nuclear plant, its Japanese operator said on Sunday, the latest in a series of incidents at the tsunami-battered complex. Tokyo Electric Power Co (TEPCO) said tests showed that tritium, a radioactive isotope of hydrogen used in glow-in-the-dark watches, was present at levels 10 times the permitted rate. "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. "We continue efforts to prevent further expansion of contamination by construction works... and will strengthen monitoring of pollution comprehensively," it said. The new readings came after TEPCO said in late June that it had detected the highly toxic strontium-90, a by-product of nuclear fission that can cause bone cancer if ingested, at levels 30 times the permitted rate. At the time it had detected tritium at around eight times the allowed level, or 500,000 becquerels per litre. The substances, which were released by the meltdowns of reactors at the plant in the aftermath of the huge tsunami of March 2011, were not absorbed by soil and have made their way into underground water. hurriyetdailynews/toxic-radiation-again-in-groundwater-at-fukushima-tepco.aspx?pageID=238&nID=50196&NewsCatID=356
