Kyodo News, September 1, 2013: Very high radiation levels were observed Saturday at three tanks and one of the pipes connecting them at the troubled Fukushima Daiichi nuclear plant, pointing to the possibility that radioactive water may have newly leaked, Tokyo Electric Power Co. said. The radiation readings were from 70 to 1,800 millisieverts per hour [...]
JIJI PRESS, Aug. 31, 2013: Saturday’s highest reading [of 1,800 millisieverts per hour] was measured at one of the two tanks, with the radiation level jumping from 100 millisieverts.
CBS News, Aug. 28, 2013 (Emphasis Added): “What’s important is not the number itself but to give a basic idea about the extent of the problem,” authority chairman Shunichi Tanaka said [...] Tanaka said there is a much larger ongoing problem at the plant: massive amounts of contaminated ground water reaching the sea. But that problem cannot even be rated under the IAEA’s International Nuclear and Radiological Event Scale because it is unknown exactly how much ground water is escaping, how contaminated it is and what effect it is having on the sea and marine products. [...] “I’m baffled,” he said.
WSJ, Aug. 28, 2013: “It could be much more or much less,” [Shunichi Tanaka, chairman of the Nuclear Regulation Authority] added, saying that Tepco calculated the amount based on the assumption that the tank had been full. [...] A Tepco spokeswoman said “it’s true that we calculated 300 tons. We cannot say whether we will or we won’t change it later.”
NHK, Aug. 30, 2013: Major leak [...] releasing several quadrillion becquerels of radioactive particles [...] the government needs to take charge entirely.
