After the nuclear accident caused by the Great East Japan Earthquake, numerous nosebleed cases in children in the prefecture of Fukushima raised immediate worries.
しかし、東日本大震災の被災地では、原発から飛散した放射性セシウムなどが金属粒子と結び付き拡散したことが気象庁気象研究所の観測などで確認され た。東 日本一円で医療機関のエックス線フィルムが粒子で感光する現象もみられ、当初から健康への影響を疑う声が聞かれていた。
郷地所長は金属粒 子が鼻の粘膜に付着したのが引き金となった可能性を指摘しており、実際に福島原発事故では原発から飛散した放射性物質が金属粒子と結び付いているのが発見 されています。放射能を含んだ金属粒子は1日100ミリシーベルトを超える放射線を放出する物もあるようで、これが鼻の粘膜等に付着することで鼻血のよう な急性被ばく症状が発生するようです。

by Richard Wilcox, PhD
Anyone with a brain could have told you back in 2011 at the time of the Fukushima nuclear triple meltdown that Tokyo Electric (Tepco) was lying about the true condition of the Fukushima Nuclear Power Plant No. 1 (“Dai-ichi”). Four years later, Tepco officials have finally admitted that it may not be technologically possible to decommission the plant.
The long history of the criminal insanity and negligence of the nuclear industry is revealed in our book, Fukushima: Dispossession or Denuclearization? (edited by Nadesan, Boys, McKillop & Wilcox) which was published last year, and includes detailed chapters from a number of writers who document the nuclear crimes.
In the case of Tepco (Tipkill), the facts are overwhelming that not only was Fukushima an “accident waiting to happen” but rather “a foregone conclusion.” The location of the plant on soft fill soil at a low altitude near the ocean in a tsunami zone was the first big mistake of the planners, who must have graduated from the Homer Simpson school of donutology. Cost-cutting, corruption and incompetence is part of the well-documented history, which ultimately led to the triple meltdowns.
Will the destroyed reactors ultimately need to be buried in a sarcophagus as has been done with Chernobyl which now has the world’s largest moveable “building” covering it (at no small expense)? One big problem — Chernobyl was just one reactor and rests on rock-solid ground, so the radiation can’t go too far downward. At Fukushima the reactors rest on a mushy place next to the ocean which is also atop an underground aquifer/river deep below it. It is theoretically possible that the radiation could leak into that aquifer and reach Tokyo someday.
If they have to build a sarcophagus it will be Mission Impossible since the shielding would have to be underground as well. Nuclear engineer, Arnie Gundersen proposed this as the only solution and noted a complicated underground piping system would have to be installed to process the leaking radiation before it escapes to the ocean. He also said it may take 500 years to decommission Fukushima.
One of the main technical problems with retrieving the melted fuel is that it must constantly be cooled in water, but the containers are full of holes and leaks. However, as our friend Nancy Foust of the Simply Info website points out, “the International Research Institute for Nuclear Decommissioning (IRID) already includes a ‘no water’ option in their rough planning. If that is the route they will have to go then they will need to put all their effort into that research” (personal communication, April, 2015).
Focusing effort into the right research is good advice, however IRID also made the dubious claim that the fuel could be retrieved within ten years which contradicts the pessimism of other officials and draws into question IRID credibility. Somebody ought to get the story straight.
The level of BS at Fukushima is almost as deep as how far the fuel may have melted underground. One scenario from the International Atomic Energy Agency (IAEA) describes the melted fuel in a state whereby it “erodes sideways…. The final size of the pooling maximum case is 10 to 15 meters in diameter, and 6-7 meters deep– or even deeper” (3).
Fukushima Diary reports that “Tepco and the government of Japan have been saying though molten fuel had a core-concrete reaction in [the] pedestal, but [has] stopped sinking in the concrete.” Now Tepco is starting to admit the fuel may be “outside of [the] pedestal, Tepco needs to investigate the sub-basement floor of Reactor 1. It is reported that the feasibility of inspection would be confirmed in the end of 2015” (4). Maybe they are now getting ready to admit it is indeed outside the concrete floor.
Foust told me that the location of the fuel could have been determined back in 2012 using “muon” cosmic ray scanners. Apparently this was not done because Homer Simpson, who is in charge of Fukushima decommissioning, spent the funds on donuts.
Seriously, not only is this a kind of gross incompetence (which is reminiscent of the way nuclear operations have been carried out throughout most of the world since the technology was adopted) but also appears to be a blatant political cover-up. Prime Minister Shinzo Abe and the Liberal Democratic Party (LDP) want to keep news of the actual location of the fuel secret until after they have restarted a number of the currently idled reactors in Japan. Politicians lie, governments lie, corporations are amoral killing machines. Abe even admitted he lied to the Olympic committee in order to get the 2020 Olympics bid when he told them “everything is under control” at Fukushima.
Could it be these admissions by Tepco of the dire situation are part of a psychological conditioning to get more money out of the government? One should never take statements from powerful individuals or governments/corporations at face value. On the other hand, the new chief of decommissioning, Mr. Masuda, may be a more honest and intelligent engineer and sincere about getting at the problem.
Foust provides us with a useful overview and summary of the sorry situation:
At some point the true state of Daiichi will have to be made public. The true state must be known and understood in order to do the needed research towards whatever resolution is determined to be the end goal. Right now that is fuel retrieval so the buildings could eventually be torn down. The muon scans are a step in that direction. They can use those to establish if any fuel is left in the reactors or not. If you remember back to 2011 TEPCO was insisting that most of the fuel was still in the reactor vessels. As more data is completed TEPCO is forced to admit reality. The next step after the muon scans for units 1-3 is to put the Hitachi shape changing robot into containment. If that goes as planned it will tell them where the fuel is, or isn’t. That is going to be the huge bit of data. Once the fuel is located and disclosed the extent of the meltdowns will have to be admitted. IMHO this is why LDP is so intent on getting reactors restarted right now.I must remind readers that alternative energy is viable, it is here and now. Even Forbes magazine published an article by the world’s leading alternative energy expert, Amory Lovins, proving irrefutably that Japan could be a rich source for solar and wind power which could significantly diminish the need for carbon let alone nuclear energy sources.
What is problematic in all of this is that TEPCO is still involved. Because TEPCO is involved and also ultimately responsible for the bill for the entire mess, it is a conflict of interest. They want to deal with the problem but as cheaply as possible. You can’t have a challenge of international proportion and a self serving company who only cares about profits. TEPCO has a documented habit of taking concepts put forth by contractors or outside researchers then trying to do them on the cheap. Then the project doesn’t perform as planned and the money is wasted. The holding ponds are a perfect example of that.
Some of these efforts really are experiments. Nobody has tried these things before in this context. So it should be expected that some things won’t work as hoped right out of the box, some might need adjustments. But when you add TEPCO cost cutting to that challenge is becomes very problematic.
As far as the condition of the reactors. We had a pretty good idea in 2011 about what took place in the three melted down units. TEPCO won’t admit the possibility of something until there is no denying it so it is a slow process of enough evidence that some facet can no longer be ignored.
Ultimately nuclear power is rooted in the liberal ideology of unleashing nature’s potential as an inevitable process of human development. However, as Russia’s leading political philosopher, Alexander Dugin points out, “liberalism” in its truest form leads to the ultimate destruction of humanity: by replacing traditions with corporate hegemony; by replacing nature with artificial reality; and by replacing humans with robots (transhumanism) (5).
It could be argued that the wind and sun are natural sources of energy in keeping with his conservative ideology. In that sense, Dugin states correctly:
If you are in favor of global liberal hegemony, you are the enemy.References

New tests show almost all of the fuel inside one of the Fukushima nuclear plant’s reactors has melted, its operator said Thursday, the latest step in the clean-up after Japan’s worst ever nuclear crisis.
Tokyo Electric Power Co (TEPCO) said the technology, which uses elementary particles called “muon” to create x-ray style images, gave the most concrete evidence yet the fuel had dropped to the bottom of No. 1 reactor.
The data, though largely expected...
Engineers have not been able to develop a machine to directly see the exact location of the molten fuel, hampered by extremely high levels of radiation in and around the reactors.
“While our previous analysis have already strongly suggested that fuel rods had melted down, the latest study provided further data that we like to regard as progress in our effort to determine the exact locations of the debris,” said a TEPCO spokesman.
TEPCO plans to eventually use robots to locate the fuel debris as part of the decommissioning process, which is expected to take three to four decades to complete.

The Researchers Joseph Mangano* and Janette D. Sherman, working for the Radiation and Public Health Project, New York, USA, published an article titled:
Changes in Congenital Anomaly Incidence in West Coast and Pacific States (USA) after Arrival of Fukushima Fallout
The Article begins:
"Radioactive fallout after the March 2011 Fukushima nuclear meltdown entered the U.S. environment within days; levels of radioactivity were particularly elevated in the five western states bordering on the Pacific Ocean." [http://www.scirp.org/Journal/PaperInformation.aspx?PaperID=54828#.VQtsu47F9Ai]
This is an acknowledgement that fallout was falling at high levels, at least along the coast, and that public health officials knew of it. The article then asks the scientific question:
"The particular sensitivity of the fetus to radiation exposure, and the ability of radioisotopes to attach to cells, tissues, and DNA raise the question of whether fetuses/newborns with birth defects with the greater exposures suffered elevated harm during the period after the meltdown." [http://www.scirp.org/Journal/PaperInformation.aspx?PaperID=54828#.VQtsu47F9Ai]
Research like this ought to be using rhetorical questions. But there has been so much propaganda and disinformation on the subject that researchers have to act like they don't already have evidence on the subjects. And sure enough:
"increase of 13.00% in the five western states is significantly greater than the 3.77% decrease for all other U.S. states combined (CI 0.030 - 0.205, p < 0.008). Consistent patterns of elevated increases are observed in the west (20 of 21 comparisons, 6 of which are statistically significant/borderline significant), by state, type of birth defect, month of birth, and month of conception. While these five anomalies are relatively uncommon (about 7500 cases per year in the U.S.), sometimes making statistical significance difficult to achieve, the consistency of the results lend strength to the analysis, and suggest fetal harm from Fukushima may have occurred in western U.S. states." [http://www.scirp.org/Journal/PaperInformation.aspx?PaperID=54828#.VQtsu47F9Ai]
The PDF of the article contains the following [http://www.scirp.org/Journal/PaperDownload.aspx?paperID=54828]
- The Authors looked at a list of particularly gruesome birth defects and anomolies:
- Cleft palate or cleft lip,
- Down syndrome,
- Spina Bifida/meningocele
"is that the 2010-2011 rate change of these five anomalies increased more sharply in the five Pacific/West Coast states than the rest of the U.S., based on the presence of elevated levels of fallout from the Fukushima meltdown in the period following March 2011, and the well-documented pattern of risk to humans irradiated in utero." [http://www.scirp.org/Journal/PaperDownload.aspx?paperID=54828]
There was no question for them that we were hit with considerable fallout:
"The only measure of radioactivity with large numbers of measurements in the period just after Fukushima, when environmental radiation was highest (March 15-April 30, 2011), along with the prior year, is not a specific isotope, but airborne beta emitters, or “gross beta”. During this 47 day period, well over 1000 samples with detectable concentrations were collected by the EPA at over 100 U.S. stations."
And note this is a proxy, but under-reports radiation exposure. And they present the statistics in a table:
They then note about the first table:
"For most of the period January 1 to October 4, the ratio of 2011 to 2010 beta averages was similar across the U.S. (0.983 for 18 sites in the western states, 1.018 for 31 non-western U.S. sites). But in the period March 15 to April 30, immediately after Fukushima fallout arrived, the 2011/2010 ratio for the 18 sites in the western states (7.345), was considerably higher than the 31 non-western U.S. sites (2.397). Although this is not a comprehensive assessment of dose by geographic area, it supports the belief that the greater exposures from the meltdown occurred in the five western states, using a broad measure of radiation such as gross beta. Appendix 1 shows the radiation measurement sites used. The group that will be most susceptible"
Again the wiggle words, imposed on scientists due to the confidential nature of their sources and the clamp of top security placed on all things nuclear, including those things that affect whether we know they are killing us, damaging our babies before they are born, or not.
Then they provide associated rates of Birth rates, before and after, in a second table as a baseline:
This allows them to use reported birth defect data and correlate it against the period April to November 2010 and 2011. They measured:
"A 2010-2011 increase in birth defect rates was observed for each of the five states, including Alaska (+69.52%), California (+11.88%), Hawaii (+3.90%), Oregon (+8.87%), and Washington (+15.53%). Compared to the −3.77% decline for all other U.S. states, only the California increase achieved statistical significance (CI0.001 - 0.167, p < 0.05), as 58% of the birth defects in the five states occur to California residents. The unusually large rise in Alaska is countered by the small number of cases (10 and 15 for each year), rendering the change not statistically significant."
But here's the thing. They make claims of statistical correlation and then discount them for Alaska as "not statistically significant" for lack of numbers. This may be valid scientific-speak. But if someone observes a 69% increase in incidents of birth defects even in a small population I'm not sure the validity of the math they are using. But you see that all over science from this subject. They'll deny significance of data at the drop of a hat. They weren't forced to do that in this case. The overall evidence is "statistically significant." I'm just surprised they were allowed to publish the report. And more importantly they were allowed to admit that.
"Our hypothesis that areas in the U.S. which received elevated levels of environmental radioactivity from the Fukushima meltdown are at risk for increased birth defects is based on the documented evidence of cellular damage from radiation exposure, the particular sensitivity of the fetus to radiation, and numerous reports of elevated congenital anomaly rates after exposure to fallout from atomic bomb detonations and nuclear reactor meltdowns.
And the report sustains that hypothesis:
"We find a consistent pattern of excess 2010-2011 increases in birth defect rates in the five West Coast/Pacific states, compared to the rest of the U.S., for the eight-month period April-November. The April-November 2011 birth cohort was exposed to Fukushima radioactivity while in utero."
So the truth comes out, with buzzwords, weasel words, and caveats. But the truth always comes out.
