TOKYO (TR) – Tokyo Electric Power Company workers have reported finding the highest levels of radiation so far from its No. 3 reactor at the Fukushima Daiichi nuclear power plant since the March 11, Great East Japan Earthquake and tsunami, Bloomberg reported.
The radiation, 620 millisieverts an hour, was found on the first floor of the reactor on November 3, Bloomberg said. Radiation at those levels increases the health risk for workers, the news service reported, citing World Nuclear Association recommendations.
The news comes as TEPCO announced over the weekend it has begun decontaminating radioactive water used to cool spent fuel rods at the plant’s undamaged No. 2 reactor, Bloomberg said.
The news agency reported last week TEPCO expects a 576 billion yen ($7.4 billion) full year loss for the year ending in March, citing a statement from a government-backed compensation fund. The forecast raised the company’s deficit from the nuclear disaster to 1.8 trillion yen ($23 billion).
