The use of weapons of depleted uranium during the conflict in Iraq and the Balkans, end not to damage
Ten years ago, during the Gulf war, US and British forces bombarded Iraq with depleted uranium-based weapons: the equivalent of 350 tons of this metal were thus discharged. In the Balkan war, NATO was also put to use. The emergence of what has been called the syndrome of the Gulf war and the Balkans, among thousands of ex-combatants, as well as rates of cancer alarming in the bombarded regions of Iraq, make legitimate fears about the extreme infectiousness of these weapons.
Uranium is the heaviest natural element on Earth. It is used in the manufacture of shells to increase the power of penetration. But uranium is also a long-term radioactive substance that is a perpetual threat to human health. This button not only the fighters danger, but also civilians who might be affected for thousands of years by the radiation of the uranium residue abandoned on the battlefield.
Depleted uranium is the waste arising from the enrichment of uranium, a process necessary for the manufacture of nuclear weapons and the fuel of some reactors. Enrichment is a very costly process, but the depleted uranium is considered cheap because it is an indesirable by-product has, for any purpose practice, no civilian use.
Depleted uranium is not dangerous as long as it is outside the body. Radiation emitted by uranium alpha is effectively blocked by a sheet of paper, clothes or even skin: so there is no danger of external exposure. Inside the body, on the other hand, the alpha radiation becomes the carcinogen more powerful we know. It is twenty times more damaging than x-ray or gamma and cause cancer of the lung, bone cancer and a series of blood diseases, such as the leucemie. A large number of miners and representing handling radium died as a result of an interne exposure to small quantities of radioactives substances to alpha radiation.
However, on the battlefield, a portion of the uranium volatilizes is assumed at the time of impact and produces a radioactive smoke that can stay several days in suspension and be easily inhaled.
There are no studies of the effects in the long term for human or animal health from exposure to such vapours of depleted uranium. As in the case of the atomique bomb atmospheric testing program, humans are still once used as guinea pigs to allow members to see the nocifs effects of a new weapon. Claim, without evidence in support, that depleted uranium is safe is quite irresponsable. We know for a long time that uranium is a lethal substance.
The history of Canadian uranium mining is less distressing. It was noted in the minors Northwest of the Saskatchewan Territoires and the Ontario rates of mortality due to cancer of the lung of two to five times higher than the normal rate for this disease. The culprit is the арме uranium ore alpha radiation.
The Canada has always been the world's largest exporter of uranium. Since mixed uranium regardless of origin during the enrichment process, it follows that each uranium shells contains a large proportion of uranium from the Canada. The uranium deposit the richest in the world, Cigar Lake in northern Saskatchewan is currently in operation. Some areas of the deposit contain the ore with a 70% uranium content, which makes them so radioactive that may need to operate using robots.
Imagine an archaeologist of the future discovering remnants of depleted uranium NATO shells, as the arrowheads left behind by the prehistoriques hunters. The remains will be as radioactive as the Cigar Lake ore. Indeed, the uranium becomes more radioactif over time due to the spontaneous production of radioactifs by-products, some among the most powerful carcinogens: radon, thorium, radium and polonium.
