Toxic radiation ‘in groundwater’ at Fukushima via France24

AFP – 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.


TEPCO said last week it would ask Japan’s nuclear watchdog for the green light to re-fire two of the seven units at the world’s biggest Kashiwazaki Kariwa nuclear plant in Niigata prefecture, a move rebuked by local leaders.

Tens of thousands of people were forced from their homes by the threat of radiation after the tsunami and Fukushima disaster, with some still unable to return.

Although the nuclear accident is not officially recorded as having directly killed anyone, the natural disaster claimed more than 18,000 lives and was one of Japan’s worst ever peacetime tragedies.
