International Alarms Go up As Fukushima Alert Level Raised

By Jon Queally
In the most serious action since the nuclear plant was first damaged in 2011, Japan's Nuclear Regulatory Authority is on the verge of raising the international alarm-and the official threat level-over the spiraling crisis at the Fukushima Daiichi plant.

By elevating the severity status from level 1 to level 3 on the eight-level International Nuclear and Radiological Event Scale (INES), the NRA has made a clear indication that the situation is worsening more than two years after the initial disaster and following recent reports of newly discovered leaks of highly radioactive water from several sources.

As Reuters reports, the U.N.'s International Atomic Energy Agency (IAEA) said on Wednesday it viewed the situation at Fukushima "seriously" and was ready to help if called upon, while nearby China said it was "shocked" to hear contaminated water was still leaking from the plant, and urged Japan to provide information "in a timely, thorough and accurate way".

Shunichi Tanaka, head of the NRA, told reporters that the plant has become an amusement park's house of horror, with newly discovered leaks and and repeated failings by the plant's owner TEPCO to make meaningful progress in the cleanup.

"I don't know if describing it this way is appropriate, but it's like a haunted house and, as I've said, mishaps keep happening one after the other," he told reporters. "We have to look into how we can reduce the risks and how to prevent it from becoming a fatal or serious incident."

As the Japan Times reports:

The NRA said about 300 tons of highly radioactive water has leaked from tank No. 5 in the H4 area of the damaged plant. In total, it said, the nuclear materials released into the environment has been estimated at several thousand terabecquerels, converted into radioactive molybdenum 99.

"This is comparable to level 3, given the standards for the radiation barriers and management of a facility," the NRA said in a document released Wednesday.

Raising the severity rating would be one of the most serious actions taken since the March 11, 2011, mega-quake and tsunami led to three reactor meltdowns.

"I'm concerned most about how such tanks with high levels (of radioactive water) are increasing rapidly," said Tanaka, referencing more than 1,000 water storage tanks now spread out around the crippled facility.

Fukushima Radiation Alarms Doctors

By Dahr Jamail
Scientists and doctors are calling for a new national policy in Japan that mandates the testing of food, soil, water, and the air for radioactivity still being emitted from Fukushima's heavily damaged Daiichi nuclear power plant.

"How much radioactive materials have been released from the plant?" asked Dr Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo's Radioisotope Centre, in a July 27 speech to the Committee of Health, Labour and Welfare at Japan's House of Representatives.

"The government and TEPCO have not reported the total amount of the released radioactivity yet," said Kodama, who believes things are far worse than even the recent detection of extremely high radiation levels at the plant.

There is widespread concern in Japan about a general lack of government monitoring for radiation, which has caused people to begin their own independent monitoring, which are also finding disturbingly high levels of radiation.

Kodama's centre, using 27 facilities to measure radiation across the country, has been closely monitoring the situation at Fukushima - and their findings are alarming.

According to Dr Kodama, the total amount of radiation released over a period of more than five months from the ongoing Fukushima nuclear disaster is the equivalent to more than 29 "Hiroshima-type atomic bombs" and the amount of uranium released "is equivalent to 20" Hiroshima bombs.

Kodama, along with other scientists, is concerned about the ongoing crisis resulting from the Fukushima situation, as well as what he believes to be inadequate government reaction, and believes the government needs to begin a large-scale response in order to begin decontaminating affected areas.
