Effacer Fukushima

censureLes faits présentés ci-dessous sont réels. Ils ont servi et servent à atténuer l’impact d’informations dramatiques sur l’industrie nucléaire, voire à faire oublier aux hommes qu’une catastrophe de grande ampleur a lieu sur la Terre, celle qui a commencé il y a un an à Fukushima.
Toutes les astuces utilisées pour cacher les données, pour minimiser les dangers, pour éviter de reconnaître les responsabilités seront évidemment réutilisables pour la prochaine catastrophe qui ne manquera pas d’arriver bientôt, selon les lois statistiques, à l’un des 440 réacteurs répartis tout autour de la planète.

Depleted Uranium Contamination: A Crime

Depleted Uranium Contamination: A Crime against Humanity




Global Research, March 26, 2012

This article is part of a longer essay on Depleted Uranium weapons, nuclear reactors and their environmental health impacts.

In this article the long term consequences of radiation contamination from unilateral aggression of the US and NATO countries on South and West Asia are discussed. Afpak region is being bombed daily and the cold blooded murder of nine kids out of the seventeen killed is just a small blip when billions are done in.

The world needs a public trial of political leaders for war crimes and genocide. 

Depleted Uranium or DU [1] encased bombs that have been used since 1991 by US and NATO forces knowing well that the use of DU weapons is illegal being weapons of mass destruction [WMD] and amounts to War Crimes. These weapons were used in Gulf War 1 against Iraq, then in the Balkans and later, after 9/11 events, in Afghanistan, Iraq, North Africa, Libya and now being used in Drone bombings in Pakistan.

“When 20 years ago I stated at the United Nations Conference on the Environment and Development in Rio de Janeiro that a species was in danger of extinction, I had fewer reasons than today for warning about a danger that I was seeing perhaps 100 years away.” Fidel Castro Ruz - March 21, 2012
Area Deniability Weapon

‘Depleted Uranium’ has nothing depleted about it: when this potent hard metal hits a solid surface like concrete or a battle tank, the temperature at the point of impact reaches over 40000C and turns the projectile into uranium oxide gas. These gases are picked up by the wind and carried all over the world creating vast areas of secondary contamination. Based on the population within the contamination map [Map 1], over 35% of India’s population received a heavy dosing of DU aerosolized uranium nano particles within months of the start of Afghan and Iraq wars. [2]

The total estimated population within the two circles is nearly a billion[3] ‘The capitals of 19 countries are within 1000 mile radius and include New Delhi (621 miles), Islamabad (232), Bishkek (651), Beirut (515), Cairo (806), Ankara (785), Jerusalem (546), Damascus (468), Kuwait City (347), Nicosia (643), Teheran (429), Abu Dhabi (856), Amman (503), Riyadh (615), Ashgabat (645) and so on.’ [3] Countries like India, Pakistan, Nepal, Afghanistan, Iraq, and some Central Asian States do not even have well established, dependable cancer screening facilities, let alone determining whether the illness is due to depleted uranium contamination or careless handling of toxic pesticides in the farms as was fobbed off by a very ‘respectable’ Indian environmental group. If you think that the population of contaminated regions has gone up, think again; it may have dropped significantly and not even India conducts honest Census operation. Asia, Europe and North Africa are slowly becoming sterile; the only virile bastards are those very leaders who screw 4 or 5 year old boys and girls, white boys and girls, often kidnapped by their own police. [4]

The total land area of earth is about 57.3 million square mile, which implies that roughly 8% of total land area is now contaminated. Add another 6-8% of the landmass within 1000 mile radius of Bosnia, Kosovo, Libya, and Sudan and you can guess that the entire West, Central and South Asia, half of Northern Africa and almost entire Europe is contaminated with DU aerosolized nano particles. While the spineless idiots in bureaucracy, foreign services, and the army worldwide are merrily radioactive, those “dumb stupid” soldiers from US and NATO forces are dying. Even the Indian armed forces are using these lethal weapons and they won’t even know why they died in peacetime. According to one report DU weapons have been sold to 27 countries and India is one of them.

According to Admiral Vishnu Bhagwat:  
“The long-term effects from over a decade of DU exposures are emerging in Southern Iraq. They are devastating. The increased quantities of radio-active material (including non-depleted uranium), used in Afghanistan are 3 to 5 times greater than Iraq 1991. In Iraq 2003 they are already estimated to be 6 to 10 times 1991 and will travel through a larger area and affect many more people, babies and unborn. Countries within a 1000 mile radius of Baghdad and Kabul are being affected by radiation poisoning that includes the Capital, New Delhi, where the ruling elite lives. … If we think cancer is a problem now wait until more DU is released in wars against terror and for ‘regime change’, on ‘mistaken’ Intelligence reports.” [5] 
The Wind Carries these Deadly Particles and Gas

Each time southwesterly air currents rise up over North Africa and West Asia, they pick up radioactive nano particles and blow right across India. These winds also blow across the Himalayas where these particles are rained out or snowed out. These particles are carried by the perennial Himalayan Rivers irrigate the agriculture lands that feed 1.6 billion Asians. I know these parts. 

 “Nine days after the start of the American president's 2003 ‘shock and awe’ uranium bombing campaign in Baghdad, an invisible radioactive uranium oxide gas cloud swept through Britain's towns and countryside and throughout Europe.” Scientists like Dr. Chris Busby and Saoirse Morgan, shocked Europe in a Sunday Times of London article on Feb. 19, 2006 that Aldermaston radiation monitoring centre which Dr. Busby oversaw, had shown high level of radiation. By tracking airflow pattern from West Asia to Europe during the time period, they came to a conclusion that the radiation level was high from the bombing raids over Iraq. 
[6]
 
Bob Nichols says, “The deadly uranium oxide gas measured about 48,000 radioactive particles per square meter. The average radioactive dose, according to official government index based calculations, was about 23 million radioactive particles for the average adult male in Britain and Europe.” That is sufficient dosing to turn the entire population sterile. [7] Just one nice and juicy ‘government defined depleted uranium’ is lethal enough.

In so far as India, South Asia, and the Himalayas are concerned, the airflow patterns from West Asia are regularly reported in major national dailies. What they don’t report is that these air currents carry depleted uranium particles at low, medium, and high altitude, from West Asia, North Africa, Afghanistan and Pakistan across India, the Himalayas into China.  This typical airflow pattern continues across Asia, and is carried around the world mixing with the global atmosphere within weeks. Further evidence comes from scientists [who have expressly forbidden me to disclose their name and place of work] who have tracked abnormal air current movements from the Gulf to Delhi, sometimes under “bone-dry” conditions. In Image 3, I have given the normal cloud movement from the same source. In Image 4, one can clearly see that while there is no cloud cover and there was a strong surface wind towards the mid-Arabian Sea, the streak was found moving towards Delhi. The same scientist further notes that the time for such “incursions” is normally between 6PM and 6AM.

So, the question is: what is going on? Meteorological experts suspect that some entities are regularly attempting to modify South Asian weather pattern. These have been tracked during Monsoon months too and these scientists say that ‘someone there is trying to inflict untimely weather change over the Indian peninsula.’ [8]

It actually means that someone is artificially directing air currents from West Asia to pass over Northern India, particularly Delhi. It is also well known that weather modification technologies have been in existence for many decades and one is known as HAARP. [9]

The Equation

Uranium isotope U238 is a natural substance and all life forms have trace amounts from ingesting food and water. Another isotope of uranium U235 is also naturally occurring substance. The ratio of naturally occurring U238 to U235 is 137.88. Human body can cope with this ratio. However, the use of depleted uranium, the primary waste product of the uranium enrichment process, in weapons upsets this ratio. Enriched and depleted uranium are both mutagenic materials; they attack DNA structure and alter it. Exposure to radiation from nuclear explosions and to the subsequent dust cloud is serious enough. The insidious aspect of the nano-particles of U235 dust is that they are very easily ingested, and being so tiny, they find their way into individual cells in the body, wreaking havoc from their constant radiation, and as a highly toxic heavy metal.



It means that the use of depleted uranium weapons can compromise the future quality of human population and all life forms. Responsible scientists had warned that DU weapons are WMD and must not be used. Yet DU weapons are being extensively used in Afghanistan particularly in the eastern parts, including the heavily populated Kabul and Jalalabad. Studies conducted by Uranium Medical Research Centre (UMRC) showed a ratio of 237 times in returning Gulf War I British soldiers, which ‘indicated the presence of 30-50% of DU mixed with natural uranium.’ [10]

During 2002 the UMRC research team conducted a series of field tests in Afghanistan. In Jalalabad it found concentrations of 400 to 2000% above normal level. At Nangarhar, the concentration was 100 to 400 times; every person donating urine sample was contaminated. Doug Westerman met the research team and this is what he reports: ‘In Afghanistan, unlike Iraq, UMRC lab results indicated high concentrations of NON-DEPLETED URANIUM, with the concentrations being much higher than in DU victims from Iraq. Afghanistan was used as a testing ground for a new generation of "bunker buster" bombs containing high concentrations of other uranium alloys.’ [11]

Discussions and email exchanges with UMRC team clearly showed that they were shocked by the public health impact of the use of these weapons. Dr Miraki says that every bombsite that he has visited and investigated, he finds that people are ill. The civilian population presents symptoms consistent with internal contamination by uranium." “Asaf Durakovic, UMRC’s president and a former US army adviser, believes that exposure to DU weapons may have brought a rise in birth defects as well as “symptoms of muscular-skeletal pains, immune system disorders, lung disease, and eventually cancer. “ It is an excellent way to kill a large number of people without gas chamber. And Punjab, Haryana, Himachal and Delhi are all in that juicy soup.

The Punjab Conundrum

The uranium contamination in Punjab confirms what has been well known around the world. Tests on children’s hair showed high level of uranium but lower than some tested in Himachal Pradesh. Elements like copper, chromium, zinc, lead, mercury, and uranium and poisons such as arsenic, show up in the hair. The important thing in the Punjab case is that Dr Carin Smit, a South African toxicologist associated with ‘Defeat Autism Now’ [DAN][and autism in children is directly related to the mercury poisoning from enforced vaccinations of poor households] found uranium in hair but the Punjab Government said that it is Central Government’s problem!! DAN has a solid reputation for in-depth study; the Punjab Government has a reputation for being one of the most corrupt and inhuman. [12]

Toxic elements don’t just appear in children’s hair because it is “Central Government’s” problem. These bastards should know that it their problems too; their own fucked up lives are highly radioactive.

I conclude this essay by warning the people around the world that (a) the US and NATO forces have indiscriminately used DU bombs and bullets and often DU mixed with enriched uranium [U235 and U234] and they continue to use these weapons in all war zones, and (b) the Pentagon is planning to use GBU-57A/B which is also known as Massive Ordnance Penetrator or MOP designed to penetrate 60 meters of concrete. It is for this reason that I had republished my 2006 paper in which I had warned that nuking Iran could kill millions across South Asia, in Iran, Afghanistan, Pakistan and India. [13]
I again quote Fidel Castro Ruz, “the United States is about to commit and lead the world towards the greatest mistake in its history.

Notes[1] “Depleted uranium (DU) is a man-made, radioactive, heavy metal derived from uranium ore. Naturally occurring uranium ore (rock in which the uranium concentration is approximately 1,000 or more parts per million) is mined and processed to yield a much more concentrated substance, one that is virtually pure uranium. Natural uranium exists in three isotopic forms and contains 99.274% U238, 0.72% U235, and 0.0057% U234 by weight. DU, a by-product of uranium enrichment, has an isotopic content of 99.75% U238, 0.25% U235, and 0.005% U234. As part of the effort to secure fissile uranium, many thousand tons of DU have been generated.” Since DU is 1.7 times denser than lead, it penetrates hard surfaces. [The authors] “reviewed toxicological data on both natural and depleted uranium. We included peer reviewed studies and gray literature on birth malformations due to natural and depleted uranium. Our approach was to assess the "weight of evidence" with respect to teratogenicity of depleted uranium.” The authors conclude that “animal studies firmly support the possibility that DU is a teratogen. While the detailed pathways by which environmental DU can be internalized and reach reproductive cells are not yet fully elucidated, again, the evidence supports plausibility. To date, human epidemiological data include case examples, disease registry records, a case-control study and prospective longitudinal studies.”

[2] The term ‘Area deniability weapons’ was coined by John McCarthy who is Vietnam veteran and who now spends much of his time to expose the fraudsters who run the US Government from Washington DC. While illegal wars were unilaterally declared by the US under mentally challenged Baby Bush guided by that scoundrel Tony Blair, our spineless leader Atal Bihari Vajpayee wanted to be a party to this mayhem. And later Manmohan Singh continued to promise billion dollar businesses to the paedophiliac western leaders. Manmohan smiles only in their company; for Indians he has pasted a scowl across his non-existent mouth.

The Punjab Government knows that DU contamination is going on. The Indian armed forces and their top generals also know this. The Government of India also knows this. The people should know that their lives are at stake and they should seek to try these elected criminals for collusion with war criminals.

Svolta nell'inchiesta su Quirra


Svolta nell'inchiesta su Quirra che vede 20 indagati

Le analisi del perito della procura rilevano la presenza di cerio e torio. Tra gli indagati militari, sanitari e anche il sindaco di Perdasdefogu Walter Mura
    di Valeria Gianoglio, La nuova Sardegna PERDASDEFOGU. La grande novità si chiama «cerio». È un metallo delle cosiddette “terre rare” che viene utilizzato nella fabbricazione artificiale del torio. Per il consulente del pm Domenico Fiordalisi, Evandro Lodi Rizzini, non ci sono dubbi: c’era anche cerio, nelle ossa della maggior parte dei pastori riesumati nell’ambito dell’inchiesta su Quirra. Era nelle tibie analizzate, in buona compagnia con il torio, come già si sospettava da tempo. Il torio era in «una quantità che presenta un andamento crescente con l’età per i deceduti che hanno esercitato pastorizia nel poligono».

    Ma è stata proprio la presenza del cerio, ad allarmare la procura: perché in quanto elemento artificiale e non comune in natura, non ci si aspettava di trovarlo nelle salme degli allevatori. Ha una svolta tutta chimica, dunque, l’inchiesta sul poligono di Quirra condotta dal procuratore Domenico Fiordalisi. Una svolta che è approdata avant’ieri con venti avvisi di chiusura delle indagini notificati dalla squadra mobile nuorese e dalla forestale ad altrettanti indagati eccellenti. Sei generali indagati per omissione dolosa aggravata di cautele contro infortuni e disastri: Fabio Molteni, Alessio Cecchetti, Roberto Quattrociocchi, Walter Maulon, Carlo Landi, Paolo Ricci. Due colonnelli comandanti del distaccamento di capo San Lorenzo accusati anch’essi dello stesso reato dei primi sei militari: Gianfranco Fois e Fulvio Ragazzon, insieme al responsabile del servizio di prevenzione e protezione del poligono dal 2000 fino al 2008, Walter Carta. Tre componenti della commissione del ministero della Difesa accusati di omissione dolosa aggravata di cautele contro infortuni e disastri: Giuseppe Di Donato, Vittorio Sabbatini, Vincenzo Mauro. Quattro docenti universitari e tecnici dell’istituto di scienze ambientali di Siena, Francesco Riccobono, Giuseppe Protano, Fabio Baroni, Antonello Luigi Di Lella. Due chimici dell’Sgs, Gabriella Fasciani e Gilberto Nobile, già indagati dalla prima ora per falso ideologico e adesso anche per ostacolo aggravato alla difesa di un disastro. Il medico del lavoro e docente universitario, Pierluigi Cocco, accusato, insieme al sindaco Walter Mura, tra le altre cose, anche di favoreggiamento aggravato.
    I bambini malformati. Tre generali, in particolare, ovvero Molteni, Cecchetti e Quattrociocchi, tutti ex comandanti del poligono di Quirra, sono accusati anche di aver «ostacolato l’opera di difesa in caso di disastro e omesso di riferire alle Aziende sanitarie di Lanusei e di Cagliari, e ai sindaci di Escalaplano e di Villaputzu e alle altre autorità competenti, che da molti anni avvenivano, con modalità illecite, brillamenti nel poligono in una zona che per le particolari caratteristiche orografiche poteva corrompere, adulterare o addirittura avvelenare le due sorgenti di acqua di Escalaplano e della frazione di Quirra». In quelle zone, si legge nell’avviso di chiusura indagini emesso dal procuratore Fiordalisi, «si erano più volte verificati casi di bambini gravemente malformati» e si cita il caso di una donna di Escalaplano «ancora in vita tra incredibili sofferenze. Poco prima della nascita, la sua abitazione è stata raggiunta dalle polveri dei brillamenti militari portate dal vento».
    I radar “citotossici”. Qualche novità, rispetto alle indagini degli ultimi mesi, emerge anche intorno alle analisi fatte sulle emissioni elettromagnetiche delle postazioni radar del poligono. I test, in quella occasione, ovvero nel giugno scorso, non avevano trovato nulla di anomalo o di potenzialmente pericoloso per la salute umana. Ora, tuttavia, la procura ogliastrina dice di aver scoperto il perché: qualche addetto alle postazioni aveva abbassato la potenza dei radar prima del test che risultò, dunque, secondo la procura, assolutamente falsato.

    «Nessuna cautela». I docenti universitari e tecnici senesi indagati, Riccobono, Protano, Baroni e Di Lella, sono invece accusati di aver contribuito «a esporre alla radioattività militari, civili e pastori, nonché i numerosi animali da allevamento, con l’artificio di presentare come indagine tossicologica l’indagine geochimica effettuata, senza denunciare il grave pericolo delle anomale concentrazioni di torio riscontrate nelle aree che sono considerate “ad alta intensità militare”».

    Cancellation of the Belene nuclear plant

    “Nuclear Banks, No Thanks!” coalition welcomes cancellation Belene nuclear plant

    Cancellation Bulgarian nuclear power plant sends clear signal to banks that nuclear industry is a dying business; the future is in renewables

    Nijmegen, Mar 29 2012 | Coalition “Nuclear Banks, No Thanks!”
    Yesterday, the Bulgarian government officially announced the cancellation of the Belene nuclear power project. BankTrack and other members of the “Nuclear Banks, No Thanks!” coalition applauds this decision after years of uncertainty around the project.
    Jan Haverkamp, nuclear expert consultant for Greenpeace, comments : “We are extremely happy that Bulgaria finally pulled the plug from the Belene nuclear power project. The power station was to be built in a seismic active zone, where in 1977 120 people lost their lives in an earthquake only 14 km from the planned site, in the town of Svishtov. Finally, the Bulgarian government has seen that the facts on safety, high costs and energy dependency from Russia cannot be ignored. This is a great day for all that kept the debate and opposition alive over the 25 years it took from the first ideas to the final out."
    The project was already canceled once in 1992, after fierce local opposition on environmental grounds and an economic downturn after the fall of communism. When in 2002 plans were revived to construct Belene this again sparked strong local opposition. The situation became especially tense in 2004 when local organic farmer and Greenpeace activist Albena Simeonova received death threats after Greenpeace joined court proceedings against the flawed Environmental Impact Assessment.
    Heffa Schücking, from the German NGO urgewald, continues: “The opposition to Belene went international from 2006 onwards when Western potential investors and financiers were approached. We had to fight against RWE as 49% strategic investor, who quit the project in 2009, as well as the involvement of French bank BNP Paribas, which finally withdrew its involvement in 2010. Other banks and utilities we had to pressure to stay out of the project included Deutsche Bank, UniCredit, Citi, E.ON, Electrabel and recently HSBC that acted as advisor to the Bulgarian government. Today is really a huge success and a great achievement for Bulgarian and international civil society.”
    Yann Louvel, climate and energy campaign coordinator for the BankTrack network, concludes: “The official cancellation of the Belene nuclear power plant project sends a clear signal to banks that, after the Fukushima nuclear catastrophe, the nuclear industry is a dying business, It has never been more risky to fund nuclear plants, both financially and in terms of reputational risk with customers. Banks need to draw a clear lesson and stop funding nuclear and invest instead in the future, in energy efficiency and renewables. They need to immediately abandon the worst nuclear dodgy deals around the world, such as Mochovce (Slovakia), Temelin (Czech Republic), Angra 3 (Brazil) and Jaitapur (India). As with Belene, we will continue to confront them until this happens.”

    Fukushima Pref. deleted 5 days of data


    Fukushima Pref. deleted 5 days of radiation dispersion data just after meltdowns


    The SPEEDI system is demonstrated at the Nuclear Safety Technology Center in Tokyo. (Pool)

    The Fukushima Prefectural Government revealed on March 21 that it deleted five days of early radiation dispersion data almost entirely unread in the wake of the meltdowns at the Fukushima No. 1 nuclear plant.
    The data from the System for Prediction of Environmental Emergency Dose Information (SPEEDI) -- intended to predict the spread of radioactive contamination, information vital for issuing evacuation advisories -- was emailed to the prefectural government by the Ministry of Education, Culture, Sports, Science and Technology.
    According to the prefecture's disaster countermeasure office, just after the March 2011 quake and tsunami, its dedicated SPEEDI terminal was unable to receive data due to effects of the disasters. Therefore, prefectural officials asked the Nuclear Safety Technology Center, which operates SPEEDI, to send data via email on March 12, 2011 -- one day into the nuclear crisis. The Nuclear Safety Technology Center then sent the data hourly starting at 11:54 p.m. that day. The Fukushima Prefectural Government, however, deleted all the data it received from March 12 to about 9 a.m. March 16.
    The prefectural government's nuclear center in Okuma, one of the towns hosting the Fukushima No. 1 plant, received emailed data once at midnight on March 11, but the disaster countermeasure office in the prefectural capital was not aware of it.
    "We failed to share the information amid all the confusion, and the fact that we had asked for the information to be sent by email hadn't been shared within the countermeasure office," said Yoshihiro Koyama, head of the prefecture's nuclear safety measures section. "We have not been able to confirm when the data was deleted and by who."
    At around 10:30 a.m. on March 13, 2011, the disaster countermeasure office confirmed for the first time that it had received data from the central government's Nuclear and Industrial Safety Agency by fax. But the disaster countermeasure office judged that "the data is useless because the predicted amount of released radiation is unrealistic."
    The Fukushima Prefectural Government also failed to give the data to the people of the prefecture and local municipalities partly because the central government was supposed to release such data in the first place.

    US Gov’t: Widespread contamination throughout northern Japan



    US Gov’t: Widespread contamination throughout northern Japan, including Tokyo — “Entire region would be required to be posted as radiological area”


    Dr. [Deanne J. Idar, CIV OSD POLICY],
    Given that much of the call was spent describing the current radiological status on the ground in Japan, I think a short summary of that status would be useful in the telecon summary. Here is a proposed paragraph:
    “The nuclear accident in Japan has resulted in widespread deposition of radioactive contamination throughout the northern part of Japan, including the metropolitan Tokyo area. Surface contamination levels in this entire region would be required to be posted as radiological area if they were at a U.S. licensed facility or DOE site. Any materials leaving Japan have the potential for low levels of radioactive contamination. Thus, the discussion about materials in DOD possession is indicative of similar materials that are entering commerce from Japan. In the DC and IPC meetings earlier this week, it was agreed that the limit of 4 Bq/cm2 for commerce was going to be acceptable and posed no health risk.”
