Radiation levels inside a stricken reactor at Japan’s Fukushima nuclear plant have hit a record high capable of shutting down robots, in the latest challenge to efforts aimed at dismantling the disaster-hit facility.

Radiation levels inside the plant’s No. 2 reactor were estimated at 530 sieverts per hour at one spot, Tokyo Electric Power Co (TEPCO) said Thursday after analyzing images taken by a manually operated camera that probed the deepest point yet within the reactor.

Even after taking a 30-percent margin of error into account, the radiation level was still far higher than the previous record of 73 sieverts per hour detected by sensors in 2012 though at a point not as deep, TEPCO said. Radiation exposure at 530 sieverts per hour would effectively shut down TEPCO’s planned robot camera probe in under two hours.

But TEPCO said the high reading focused on a single point, with levels estimated to be much lower at other spots filmed by the camera. It added that the planned robot probe would not sustain severe damage because it was unlikely to linger for too long at a single point.

The three cameras mounted on a caterpillar-type robot are designed to withstand up to 1,000 sieverts in total. TEPCO said the radiation is not leaking outside the reactor. A massive undersea earthquake on March 11, 2011 sent a huge tsunami barrelling into Japan’s northeast coast, leaving more than 18,000 people dead or missing, and sending three reactors into meltdown at the Fukushima plant in the worst such accident since Chernobyl in 1986.

Japan’s government said in December that it expects the total costs – including compensation, decommissioning and decontamination – to reach 21.5 trillion yen ($190 billion) in a process likely to take decades as high radiation levels have slowed operations.

TEPCO has said it plans to eventually use robots to locate the fuel debris as part of the decommissioning process.

Images of the wreckage inside the No. 2 reactor captured by the camera show that the metal grating under the pressure vessel which contained nuclear fuel has largely sunken in, causing a hole about one metre wide.

Black debris that could be melted fuel is also seen in the images. Fuel may have melted through the vessel and damaged the grating but the exact cause was not determined, TEPCO spokesman Tatsuhiro Yamagishi said Friday. “It may have been caused by nuclear fuel that would have melted and made a hole in the vessel, but it is only a hypothesis at this stage,” he told AFP.

“We believe the captured images offer very useful information, but we still need to investigate given that it is very difficult to assume the actual condition inside,” he said.

Tokyo Contaminated & Not Fit for Habitation, Doctor Says

All 23 districts of Tokyo contaminated with radiation, worse than at Chernobyl after the accident, and blood cells of children under ten are showing worrying changes; the WHO, the IAEA & the Japanese government cannot be trusted.

by Susie Greaves

In July 2014 Dr Shigeru Mita wrote a letter to his fellow doctors to explain his decision to move his practice from Tokyo to Okayama city in the West of Japan [1]. In it, he appeals to their sense of duty to answer the anxieties of parents in Japan who do not believe the information coming from the authorities. He says “I must state that the policies of the WHO, the IAEA or the Japanese government cannot be trusted.” and “if the power to save our citizens and future generations exists somewhere, it does not lie within the government or any academic association, but in the hands of individual clinical doctors ourselves.”

Mita claims that all 23 districts of Tokyo are contaminated, with the eastern area worst affected — up to 4 000 Bq/kg. (The becquerel is a unit of radioactivity. One Bq is the activity of a quantity of radioactive material in which one nucleus decays per second.) These findings confirm what the nuclear physicist Arnie Gundersen of Fairewinds Nuclear Education found in 2012, when he picked up five random soil samples in Tokyo from between paving stones, in parks and playgrounds. The levels of contamination were up to 7 000 Bq/kg; in the US, anything registering these levels would be considered nuclear waste [2].

While practising in Tokyo, Mita also discovered changes in the white blood cells of children under 10.

Independent science & independent reporting in Japan outlawed

In December 2013, the Japanese parliament passed a bill whereby public officials and private citizens could face ten years in prison for divulging “special state secrets”, and journalists, five years, for seeking to obtain classified information. The bill is widely interpreted as a way of preventing sensitive information about Fukushima (among other topics) reaching the Japanese public and by extension the rest of the world [3].

The independent organisation Reporters without Borders has downgraded Japan in its world press freedom index from 22nd place in 2012, to 53rd in 2013 and to 59th in 2014, following the passing of the state secrets bill. Reporters without Borders say that Japan“has been affected by a lack of transparency and almost zero respect for access to information on subjects directly or indirectly related to Fukushima”

The Secret Ingredients of Everything From smart phones to hybrid vehicles to cordless power drills,

Devices we all desire are made with a pinch of rare earths—exotic elements that right now come mostly from China.

Most of us would be hard-pressed to locate Inner Mongolia, Jiangxi, or Guangdong on a map. Yet many of the high-tech devices we depend on—cell phones, laptops, and hundreds of others—would not exist without an obscure group of elements mined, sometimes illegally, in those three and other regions of China.

Rare earths, as the elements are called, were discovered beginning in the late 18th century as oxidized minerals—hence “earths.” They’re actually metals, and they aren’t really rare; they’re just scattered. A handful of dirt from your backyard would probably contain a smidgen, maybe a few parts per million. The rarest rare earth is nearly 200 times more abundant than gold. But deposits large and concentrated enough to be worth mining are indeed rare.

The list of things that contain rare earths is almost endless. Magnets made with them are much more powerful than conventional magnets and weigh less; that’s one reason so many electronic devices have gotten so small. Rare earths are also essential to a host of green machines, including hybrid cars and wind turbines. The battery in a single Toyota Prius contains more than 20 pounds of the rare earth element lanthanum; the magnet in a large wind turbine may contain 500 pounds or more of neodymium. The U.S. military needs rare earths for night-vision goggles, cruise missiles, and other weapons.

“They’re all around you,” says Karl Gschneidner, a senior metallurgist with the Department of Energy’s Ames Laboratory in Ames, Iowa, who has studied rare earth elements for more than 50 years. “The phosphors in your TV—the red color comes from an element called europium. The catalytic converter on your exhaust system contains cerium and lanthanum. They’re hidden unless you know about them, so most people never worried about them as long as they could keep buying them.”

Now a lot of people are worried.

China, which supplies 97 percent of the world’s rare earth needs, rattled global markets in the fall of 2010 when it cut off shipments to Japan for a month during a diplomatic dispute. Over the next decade China is expected to steadily reduce rare earth exports in order to protect the supplies of its own rapidly growing industries, which already consume about 60 percent of the rare earths produced in the country.

Fears of future shortages have sent prices soaring. Dysprosium, used in computer hard drives, now sells for $212 a pound, up from $6.77 eight years ago. Over just two months last summer, prices on cerium jumped more than 450 percent. World demand will probably exceed supply before the end of 2011, says Mark A. Smith, president and CEO of Molycorp, an American company that reopened a rare earth mine at Mountain Pass, California, last year.

“We’re in a supply crunch right now, and it’s a pretty severe one,” says Smith. “This year the demand will be 55,000 to 60,000 tons outside of China, and everyone’s best guess right now is that China will be exporting about 24,000 tons of material. We’ll survive because of industry inventories and government stockpiles, but I think 2011 will be a very, very critical year in terms of supply and demand.”

Tokyo – The operator of the nuclear plant in Fukushima in Japan , destroyed by a tsunami in March 2011, announced Tuesday that he could not freeze radioactive water on site.

Tokyo Electric Power (Tepco), the operator of Fukushima, plans to freeze a portion of the 11,000 tons of toxic water stored in pits under two reactor buildings of the plant. Implementation of this project began in April, but the water can not freeze.

According to a spokesman for Tepco, fluctuating water levels in the tunnel under the building number two reactor prevent it from freezing into ice.

Tepco has another project in Fukushima: underground construction of an ice wall 1.4 km long around buildings four reactors to prevent radioactive water from leaking into the Pacific Ocean.
The ice wall uses the same technology as the project pits and uses the same company, the construction group, Kajima.

I’m breathing in the chemicals

I’m breaking in, shaping up, then checking out on the prison bus
This is it, the apocalypse

Enough to make my systems blow
Welcome to the new age, to the new age
Welcome to the new age, to the new age
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive

I raise my flags, don my clothes
It’s a revolution, I suppose
We’ll paint it red to fit right in
Whoa

I’m breaking in, shaping up, then checking out on the prison bus
This is it, the apocalypse
Whoa

I’m waking up, I feel it in my bones
Enough to make my systems blow
Welcome to the new age, to the new age
Welcome to the new age, to the new age
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive

All systems go, the sun hasn’t died
Deep in my bones, straight from inside

I’m waking up, I feel it in my bones
Enough to make my systems blow
Welcome to the new age, to the new age
Welcome to the new age, to the new age
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive
Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I’m radioactive, radioactive

It’s usually one of the mysteries of the deep – but an elusive giant squid has been found in a fishing net off the coast of Japan.
