Construction of a radioactive waste storage complex in a 16-square-kilometer area straddling the towns of Futaba and Okuma to start

Jan. 29, 2015
Japan’s environment ministry plans to soon start building initial facilities for storing radioactive waste stemming from decontamination work in Fukushima Prefecture, northern Japan.

They are part of the intermediate storage complex to be built in a 16-square-kilometer area straddling the towns of Futaba and Okuma.

The government earlier planned to start moving the waste to the site by the end of this month. But it canceled the plan due to delays in purchasing land and building facilities.

The government now plans to start the transport by March 11th, the 4th anniversary of the earthquake and tsunami that led to the nuclear accident in 2011.
The ministry says construction of 2 initial storage facilities, each 10,000 square kilometers, will start next Tuesday at industrial parks in the intermediate site.

The waste is to be kept there until intermediate storage facilities are completed. It remains unclear when their construction will begin, due to lack of progress in purchasing land.

Huge amounts of radioactive soil and other waste stemming from decontamination work have been kept in each municipality of the prefecture.

Municipalities are asking the government to provide a concrete schedule for transporting the waste.


31,000,000 Bq/m3 of Strontium-90 measured at the nearest boring well to Reactor 2

January 27, 2015
On 1/27/2015, Tepco announced they measured high density of Strontium-90 from groundwater in the seaside of Reactor 2.
It was 31,000,000 Bq/m3. The sampling point was the boring well, which is the closest to Reactor 2.
This is the highest density measured from this boring well, which is 10% more than the previous highest record.
The sampling date was last December. No Sr-90 data of January has been published.

Global consequences from Fukushima-like nuclear disaster; Many nations at risk of ‘great exposure’

January 28th, 2015

Study: Global consequences from Fukushima-like nuclear disaster; Many nations at risk of ‘great exposure’ — Transport of hot particles to US was especially effective during worst releases after reactor explosions — Radioactivity confined ‘close to surface’ due to seasonal factors

T. Christoudias and Y. Proestos of The Cyprus Institute, J. Lelieveld of Max Planck Institute of Chemistry (Germany), Dec 12, 2014 (emphasis added):

  • We estimate the contamination risks from the atmospheric dispersion of radionuclides released by severe nuclear power plant accidents… We present an overview of global risks… [These] risks exhibit seasonal variability, with the highest surface level concentrations of gaseous radionuclides in the Northern Hemisphere during winter [Fukushima crisis began with 10 days left in winter].
  • The model setup was evaluated… using emission estimates from… Fukushima
  • The risk posed from nuclear power plant accidents is not limited to the national or even regional level, but can assume global dimensions. Many nations may be subjected to great exposure after severe accidents.
  • Our model shows increased surface-level concentrations throughout the Northern Hemisphere during the boreal winter months compared to the summer… Not only the expected risk magnitude is higher, but the geographical extent of the high concentrations of transported radionuclides is more pronounced towards the northHorizontal advection [i.e. transfer] is more efficient in winter due to relatively stronger winds, and the concentrations are highest near the surface [and] surface level concentrations in the summer tend to be more localized in the emission region.
  • Our results illustrate that accidents… could have significant trans-boundary consequences. The risk estimate [shows] increased surface level concentrations of gaseous radionuclides in the Northern Hemisphere during winter and a larger geographical extent towards the north and the east… This is related to the relatively shallow boundary layer in winter that confines the emitted radioactivity to the lowest part of the atmosphere close to the surface…It is the view of the authors that it is imperative to assess the risks from the atmospheric dispersion of radioactivity from potential NPP accidents [for] emergency response planning on national and international levels.


JAMSTEC, Univ. of Tokyo, etc.: We show a numerical simulation for the long-range transport from the [Fukushima] plant to the US… Large-scale updraft [over] Japan from March 14 to 15 was found effective in lifting the particles [to the] jet stream that could carry the particles across the Pacific within 3 to 4 days [See study: On Mar. 15, Fukushima reactors emitted 100 quadrillion Bq of cesium into air — This one day was equal to total lifetime release from Chernobyl]… Some of the particles [had a] long-range atmospheric transport over — 10,000 km within 3 to 4 days… [R]adioactive materials were detected in that period over the east and west coasts of the U.S… In order for the particles to be transported with the jet stream, they must be lifted up from the surface boundary layer to the mid- or upper troposphere. Large-scale updraft was indeed observedon March 14 through 15[T]he westerlies in mid-March were thus particularly effective in the trans-Pacific transport of the radioactive materials…

Radioactive Baby Teeth The Cancer Link — A review

In the 50’s and 60’s there was a campaign to collect baby teeth from people around the St. Louis area driven by local doctors, scientists and teachers:

“The idea for the study was hatched in the mid-1950s during the build up of the Cold War. By then, the U.S. and Soviet Union had tested hundreds of nuclear weapons. Prevailing winds carried the radioactive debris from the U.S. tests, many of which were conducted in the desert regions of the West, to St. Louis and farther east.” [stl today article]

Using Grant Money these scientists decided to do the science:

“Funded by the U.S. Public Health Service and Leukemia Society of Missouri and Illinois, it entailed volunteers visiting schools, churches and PTA meetings, churches, libraries and dental clinics distributing registration forms. Parents mailed in their children’s baby teeth and information cards with names, addresses, birthdates and other information.” [stl today article]

The St. Louis study collected baby teeth from locals in the St. Louis area. Based on the results of sampling those teeth authorities and some of the general public realized that strontium, cesium and other contaminates were falling from the sky and getting into our food supply. People were drinking contaminated milk. What the study found was frightening:

“The study found that children born in St. Louis at the height of the Cold War in 1963 had 50 times as much strontium 90, a radioactive isotope found in bomb fallout and at nuclear reactors, in their teeth as children born in 1950 — before most of the atomic tests. Results ultimately contributed to the signing of an international treaty to ban atmospheric nuclear weapons testing.” [stl today article]

The concern that contributed to the Nuclear Test Ban Treaty should have led to efforts to end the use of nuclear energy worldwide. What the study showed was frightening,…

but the news was contained. The teeth had been sampled, but many remained in boxes. They wound up in a storage room. To be rediscovered later.

“85,000 baby teeth in shoeboxes in an ammunition bunker at Washington University’s Tyson Research Center. The teeth, packaged in small envelopes, were among those collected in the 1950s and ’60s but never analyzed for radioactive strontium.”

This has led to a follow up, epidemiological study found even more frightening data about the results of exposure to radiation.

“They were given to the Radiation and Public Health Project, which set out to advance the findings of the original study by looking at health effects on people who had elevated strontium 90 levels in their teeth as children.” [stl today article]

What they found was a correlation between baby tooth radiation levels and later cancers and mortality.

“In 2010, Mangano and Janette Sherman published a study in the International Journal of Health Services. It concluded men who grew up in the St. Louis area in the early 1960s and died of cancer by middle age had more than twice as much strontium 90 in their baby teeth as men born in the same time and area who were still living.”

Dealing with objections to the study

Of course people working in the nuclear industry jumped to defend themselves. When mainstream media published this story they usually interview Nuclear Power spokespersons who will say things like the study “confuses correlation with causation.” But we already have evidence that radioactive substances cause mutations. That mutations cause cancers. We have that from the lab. Simple deduction shows that If a person is exposed to radiation (even small amounts) there will be mutations. Given there are mutations there will be cancers.

Correlation establishes Evidence of Causation

The next objection is that a healthy immune system will deal with most mutated cells and incipient cancers. The body normally uses Killer T Cells to “order” the mutated cells to self destruct. It takes an accumulation of mutations and specific cancer generating processes for cancer to develop. So merely being exposed to cancer causing substances doesn’t mean that a particular mutagen caused a particular cancer. But laboratory evidence also shows that radiation impacts the immune system too. In severely radiated people they don’t die directly from radiation in some cases but from leukemias, cancers and Radiation induced Acquired Immune Deficiency (AIDS). So again the causation can be deduced from laboratory evidence and simple logic.

Now whether these effects are non-linear or linear is a matter for argument. I personally believe that the numbers will suggest non-linearity (Chaotic rather than purely random or simply determined). Non linearity suggests that there are probably thresholds beyond which odds start rising exponentially, but also suggests that normal curves don’t apply and that risk never falls to zero. In any case most of the arguments you hear from the officials are deceptive, simplistic and deliberately misleading. So I don’t believe the authors really believe what they are saying themselves. And the results of the Survey described in the book “Radioactive Baby Teeth Cancer Link” support that theory.

Therefore in this case correlation verifies causation.

Most of these scientists and technicians base their arguments on the notion that there is a threshold below which mutagen exposure is harmless. This is based on a much criticized study from the 1950’s, but it still gets cited. Anyway, the book “Radioactive Baby Teeth the Cancer Link” goes into detail on this:

AREVA filed a complaint against the South-East Antinuclear Coordination. 
We will not allow ourselves to be gagged !

The South-East Antinuclear Coordination has just been informed last Tuesday January 6, 2015 that a defamation suit has been filed by Areva against them for a report that they published on their website, denouncing the nuclear lobby’s penetration to the elected officials.

This attack on freedom of speech is taking place while the nuclear health crime continues here in the Rhône Valley of France, and in Fukushima, Japan.

By such attempt to gag opposition, the nuclear giant intends to silence dissent at a time when the Areva group is in financial and industrial decay (having lost 52% of its stock market value, failure of its EPR in Finland, risky investments, its Mox sales declining, especially in Japan, in question regarding its foreign budget financing etc), at a time when incidents are increasing at its ageing nuclear facilities in France and that thousands of Japanese children and adults will die slowly in Fukushima, Japan, and elsewhere as in Niger.

The South-East Antinuclear Coordination, apart fromany political party, bringing together concerned citizens acting for the immediate and unconditional cessation of the nuclear crime for public health reasons, denounces :
The fanatical ideological war that proponents of atomic destruction are waging against free thought and against the people, the arrogance and the imperialism of the nuclear lobby and of its ruling caste,
The populations health and life damages and the contamination of areas by radioactive releases in the air and in the water from each of the 125 civil nuclear facilities plus the military nuclear facilities on secret military bases located throughout the french territory. Damages deliberatedly done, and repeated daily, such as the manufacturing of the radioactive «depleted uranium» by Areva, used in weapons of war,
Neo-colonialist exploitation of Niger’s workers and resources, as well as the radioactive contamination of the territories and of the Tuareg people and other people life in this country,
The infiltation of the Stateinstitutions, and of the elected assemblies by a private interests group and their ideological relay to impose a dominant order and a state of nuclear terror on the country and the plane.

The South-East Antinuclear Coordination calls to mind that there is no harmless dose of artificial radiation.

The South-East Antinuclear Coordination calls for solidarity :
All the persons freedom-loving, attached to the right of speech and criticism,
All the collectives, groups and organizations,
To oppose this attack on freedom of speech,
To send support emails to the South-East Antinuclear Coordination :
To express their indignation to the authorities and to Areva by any way each person will define:
