The situation in Fukushima is bad enough that a Major Japanese News Outfit, the Asahi Shimbun reports that excessive radiation is killing Robots seeking to inspect the Fukushima Reactor #1. In an article titled "Nuke watchdog critical as robot failures mount at Fukushima plant" THE ASAHI SHIMBUN March 24, 2017, they report:
"These regulators are increasingly calling for a new survey methodology after recent investigations utilizing robots controlled remotely generated few findings and were quickly terminated." [http://www.asahi.com/ajw/articles/AJ201703240064.html]
The problem is not with the Robots, but with the regulators. They don't like what they are finding.
"The lower part of the reactor’s containment vessel is submerged in water where deposits of fuel debris are believed to reside below the surface after melting through in the 2011 nuclear disaster, triggered by the Great East Japan Earthquake and tsunami."
They essentially admit that all that is left is debris, that any corium left long melted through the containment and are located in water beneath it.
"At one location, the robot succeeded in placing a camera, which is combined with a dosimeter, to a depth 0.3 meter from the containment vessel floor."
But they are unable to proceed far.
"The probe measured underwater radiation levels from 3.0 to 11 sieverts per hour during the five-day survey. But it was unable to take images of the debris in the water.
A Gift that Keeps Giving
Apparently the Robots cannot get past the debris or withstand the radiation, and are dying before they are able to see any corium. Apparently these ruins are stil incredibly dangerous, still leaking large amounts of radiation, and still are a hazard to people around the world, but especially around the Pacific basin.

Nuke Experts: Fukushima plant must be entombed like Chernobyl — Reactors will remain a threat to world “for the rest of time” — “Humanly impossible” to clean up due to shockingly high radiation levels
EnviroNews World News, Feb 6, 2017 (emphasis added): The astronomical readings bring major concerns to a cleanup operation already spiraling out of control — flying blindly into territory previously uncharted in the history of nuclear power…. To top it off, 530 sieverts per hour might not be the worst cleanup workers have to worry about. TEPCO also stated that surface-level radiation readings from parts inside the plant’s pressure vessels can reach “several thousand sieverts per hour,” compounding what are already seemingly unsurmountable tasks in the decommissioning process. Esteemed nuclear expert, engineer, and former reactor operator Arnie Gundersen told EnviroNews World News in an email that the position of Fairewinds, his educational non-profit, is that radiation levels are presently way to high to remove the melted fuel, and that the reactors should be entombed, like was done with Chernobyl’s sarcophagus, for at least a century before attempting dismantlement. “[These readings do] make dismantling the facility almost impossible for 100 or more years, as the exposure to workers would be too significant,” Gundersen said.
Dr. Helen Caldicott, Feb 13, 2017: … it will be almost impossible to “decommission” units 1, 2 and 3 as no human could ever be exposed to such extreme radiation; and that this fact means that Fukushima Daichi will remain a diabolical blot upon Japan and the world for the rest of time, sitting as it does on active earthquake zones… Bottom line, these reactors will never be cleaned up nor decommissioned because such a task is humanly impossible…

Warning, this is not the result of an official study but the findings of the personal study of Kikko, a blogger who took as a base the number of hospitalized patients. But again we cannot expect the Japanese government to officially advertize it: "The number of patients diagnosed with leukemia in 2015 was about 7 times higher than the previous year."
Since 1978 when they began taking statistics, such high proportion never occured before.

The thyroid, a butterfly-shaped gland located in the front part of the neck, is responsible for producing thyroid hormones from iodine in the blood. These hormones affect your metabolism rate, which means they influence how fast or slow your brain, heart, muscles and liver work. So, yeah: They’re kind of important.

And it begins. Fukushima children forced to relocate are now speaking out as they are outcasted and bullied.
Wednesday, 13 July 2016
NHK reports that the decommissioning authority in charge of dealing with the aftermath of the Fukushima disaster is now considering a sarcophagus to entomb the failed reactors rather than attempting to remove the melted fuel, debris and buildings.
The authority told NHK they would still consider the two fuel removal techniques but they are adding the sarcophagus option to the list. They did not elaborate about why it is now being officially added to the considered options for the plant.
The idea of leaving the plant as is and creating a sarcophagus around the three melted down reactors is extremely problematic. The groundwater issue is just one problem that would be a permanent problem. Even the ice wall if it eventually works as planned can only operate for a few years. Erosion and groundwater flows would create a permanent problem for the ocean and the region around the plant. This would also leave the fuel and crumbling buildings in place. Building failures, radioactive dust and fuel debris would all still be in place. This would need to be managed not just due to aging but further natural disasters such as typhoons and tsunami. Current problems include fuel fragments that have been found in unit 1′s torus room basement water. These have been a concern as groundwater flows through these basements that if improperly managed, more of these fuel fragments could leave the basement into the groundwater.
At Chernobyl, the new cover building there is expected to be needed for 100 years while they attempt to eventually deal with the damaged building. When and how that happens is still vague decades later.

Cases of a debilitating disease that results in lesions on sea turtles off north Queensland are rising
Cases of a debilitating disease that results in lesions on sea turtles off north Queensland are rising, with a researcher suspecting a link between the disease and the health of the Great Barrier Reef.
Fibropapillomatosis caused by the herpes virus and results in lesions on the turtle's body
Lesions can grow on an animal's eyes so they cannot see predators and cannot catch food
"Hotspot" in Cockle Bay at Magnetic Island may provide clues to the disease, with turtles only 100 metres away unaffected by tumours
The disease, called fibropapillomatosis (FP), is caused by the herpes virus and results in lesions on the turtle's body.
The disease has been found across the world and more recently in places like Townsville.
James Cook University researcher Karina Jones has been studying the disease in turtles found near Magnetic Island off Townsville.
She said the disease could contribute to the death of turtles.
"It grows on their eyes, they can't see predators, they can't catch food, so sometimes they slowly starve to death — it's not a nice thing for the turtles to experience," she said.

Cleanup crews trying to mitigate Japan’s never-ending radiation crisis at Fukushima ran into more problems recently after sensors monitoring a drainage gutter detected a huge spike in radiation levels from wastewater pouring into the Pacific Ocean.
The Tokyo Electric Power Company says radiation levels were up to 70 times, or 7,000 percent, higher than normal, prompting an immediate shutdown of the drainage instrument.
The first readings came around 10 a.m. local time on February 22, setting off alarms not once but twice as radiation levels spiked to extremely high levels.
“The levels of beta ray-emitting substances, such as strontium-90, measured 5,050 to 7,230 becquerels per liter of water between 10:20 a.m. and 10:50 a.m.,” reported The Japan Times. “TEPCO requires radioactivity levels of groundwater at the plant discharged into the sea to remain below 5 becquerels.”
TEPCO shut off leaky gutter, but radiation continued to spike throughout day
The gutter was quickly decommissioned to prevent further radiation emissions, but the leaks reportedly continued throughout the day, with radiation levels hovering between 10 and 20 times higher than normal. TEPCO says it doesn’t know what caused the sudden radiation spikes.
“With emergency surveys of the plant and monitoring of other sensors, we have no reason to believe tanks storing radioactive waste water have leaked,” stated a plant official to the media. “We have shut the gutter [from pouring water to the bay]. We are currently monitoring the sensors at the gutter and seeing the trend.”

FUKUSHIMA, Japan— Ten months ago I arrived in Japan to cover a historic year—the 70th anniversary of the atomic bombings, the fifth anniversary of the 2011 earthquake and nuclear disaster, and the first visit by a sitting U.S. President to Hiroshima. I wanted to document the social impact nuclear technology has had on Japan.
Japan is the only country in the world to experience atomic war and a catastrophic nuclear meltdown. I have a unique family connection to Hiroshima and Nagasaki as a grandson of the only double crewman of the bomb missions, and I’ve spent the past five years in Japan meeting with the survivors of the bombs, or hibakusha as they are called in Japanese.
The hibakusha have been telling audiences their survival stories for decades. They experienced the bombing 71 years ago, and while they never forget their trauma and it never gets easier to describe it, each time they speak they spread their precious testimony in hopes of contributing to a world free of nuclear weapons. However when I turned my focus to Fukushima, I found it difficult to capture stories. Like Hiroshima and Nagasaki, everyone who was in Fukushima at the time of the disaster has a story, but unlike Hiroshima and Nagasaki many are struggling to find their voice.
The disaster is still fresh in the minds of the survivors. Many wish to speak out about their exposure to the radiation, or the dangers of nuclear power, but don’t know what to say, or how to describe what they went through. The following voices each depict a different aspect of the disaster and show how Fukushima has been diversely affected.
In the next few months I will finish editing the videos I have filmed in Hiroshima, Nagasaki, and Fukushima for my blogumentary that will be viewable on YouTube and Facebook at “Hibakusha The Nuclear Family.”

Have you seen images from Japan showing mountains of black bags filled with radioactive soil? You probably wondered what they are going to do with them, right?
Saturday, 2 April 2016
TOKYO – The Japanese government announced Wednesday it will recycle the material collected during the decontamination of the Fukushima nuclear plant for construction purposes if radiation levels are found to be sufficiently low.
The government plans to store the waste collected from the radiation-affected region and use it as construction material in places outside the prefecture in northeastern Japan, within 30 years, reported state broadcaster NHK.
According to the country’s environment ministry, residue showing less than 8,000 becquerel per kg could be used in future to pave roads, build anti-tsunami walls and in other public works.
Over 90 percent of the material, accumulated since the 2011 disaster, could be re-used if the contaminated elements are removed, according to the authorities, who are, however, yet to develop the technology to separate waste with high radiation levels.

With contaminated water from Japan’s crippled Fukushima nuclear complex continuing to pour into the Pacific, scientists are concerned about how that radioactivity might affect marine life. Although the ocean’s capacity to dilute radiation is huge, signs are that nuclear isotopes are already moving up the local food chain. by Elizabeth Grossman Over the past half-century, the world has seen its share of incidents in which radioactive material has been dumped or discharged into the oceans. A British nuclear fuels plant has repeatedly released radioactive waste into the Irish Sea, a French nuclear reprocessing plant has discharged similar waste into the English Channel, and for decades the Soviets dumped large quantities of radioactive material into the Arctic Ocean, Kara Sea, and Barents Sea. That radioactive material included reactors from at least 16 Soviet nuclear-powered submarines and icebreakers, and large amounts of liquid and solid nuclear waste from USSR military bases and weapons plants.
Still, the world has never quite seen an event like the one unfolding now off the coast of eastern Japan, in which thousands of tons of radioactively contaminated water from the damaged Fukushima Daiichi nuclear power plant are pouring directly into the ocean. And though the vastness of the ocean has the capacity to dilute nuclear contamination, signs of spreading radioactive material are being found off Japan, including the discovery of elevated concentrations of radioactive cesium and iodine in small fish several dozen miles south of Fukushima, and high levels of radioactivity in seawater 25 miles offshore.
How this continuing contamination will affect marine life, or humans, is still unclear. But scientists agree that the governments of Japan, the United States, and other nations on the Pacific Rim need to ramp up studies of how far this contamination might spread and in what concentrations.
“Given that the Fukushima nuclear power plant is on the ocean, and with leaks and runoff directly to the ocean, the impacts on the ocean will exceed those of Chernobyl, which was hundreds of miles from any sea,” said Ken Buesseler, senior scientist in marine chemistry at the Woods Hole Oceanographic Institution in Massachusetts. “My biggest concern is the lack of information. We still don’t know the whole range of radioactive compounds that have been released into the ocean, nor do we know their distribution. We have a few data points from the Japanese — all close to the coast — but to understand the full impact, including for fisheries, we need broader surveys and scientific study of the area.”
Buessler and other experts say this much is clear: Both short-lived radioactive elements, such as iodine-131, and longer-lived elements — such as cesium-137, with a half-life of 30 years — can be absorbed by phytoplankton, zooplankton, kelp, and other marine life and then be transmitted up the food chain, to fish, marine mammals, and humans. Other radioactive elements — including plutonium, which has been detected outside the Fukushima plant — also pose a threat to marine life. A key question is how concentrated will the radioactive contamination be. Japanese officials hope that a temporary fishing ban off the northeastern Japanese coast will be enough to avert any danger to human health until the flow of radioactive water into the sea can be stopped.......
