Reply #21: Do you discount this out of hand then?

Fiction: Alpha particles can't penetrate clothes and skin.

Fact: This statement ignores the most prevalent and dangerous pathway for uranium to get into the human body. Inhaled uranium can remain in the lungs and bones for years where it continues to emit alpha, beta and gamma radiation. Each alpha particle can traverse up to several hundred cells causing somatic and genetic alterations. Multiply this by billions of such particles and a huge amount of cellular damage becomes possible. The majority (50-70%) of the airborne DU particles sampled during the testing of 105 mm DU projectiles were in the respirable range and capable of reaching the non-ciliated bronchial tree. Studies also indicate that the half-time in the lungs is up to 5 years.

Soluble DU compounds have rapid access to the bloodstream with consequent toxic effects on the target organs and the bone where it is incorporated. Mass spectrometry results of deceased Canadian veteran, Captain Terry Riordon, confirmed that depleted uranium was present in his bone. From there it can compromise the immune system and affect the stem cells that travel throughout the body thereby affecting many other organs. Soldiers inside a tank or armoured vehicle can inhale tens of milligrams of DU after the shell goes through the tank. Compare this to the maximum allowable yearly dose in the U.S. for inhaled uranium is 1.2 milligrams per year.

As I mentioned in the post above the Uranium Medical Research Centre works in close cooperation with a former Head of Nuclear Medicine at a US Veterans Affairs' medical facility, Dr. Asaf Durakovic. He has also served as head of nuclear medicine at Georgetown University in Washington DC. It's not likely they would put up anything on the web site that Dr. Durakovic would not agree with.

And then there is also this as well.

Despite all that evidence of the harm done by DU, governments on both sides of the Atlantic have repeatedly claimed that as it emits only ‘low level’ radiation DU is harmless. Award winning scientist, Dr Rosalie Bertell who has led UN medical commissions, has studied ‘low level’ radiation for 30 years.(2 )She has found that uranium oxide particles have more than enough power to harm cells, and describes their pulses of radiation as hitting surrounding cells ‘like flashes of lightning’ again and again in a single second.(2) Like many scientists worldwide who have studied this type of radiation, she has found that such ‘lightning strikes’ can damage DNA and cause cell mutations which lead to cancer. Moreover, these particles can be taken up by body fluids and travel through the body, damaging more than one organ. To compound all that Dr Bertell has found that this particular type of radiation can cause the body’s communication systems to break down, leading to malfunctions in many vital organs of the body and to many medical problems. A striking fact, since many veterans of the first Gulf war suffer from innumerable, seemingly unrelated, ailments.

In addition, recent research by Eric Wright, Professor of Experimental Haematology at Dundee University, and others, have shown two ways in which such radiation can do far more damage than has been thought. The first is that a cell which seems unharmed by radiation can produce cells with diverse mutations several cell generations later. (And mutations are at the root of cancer and birth defects.) This ‘radiation induced genomic instability’ is compounded by ‘the bystander effect’ by which cells mutate in unison with others which have been damaged by radiation – rather as birds swoop and turn in unison. Put together, these two mechanisms can greatly increase the damage done by a single source of radiation, such as a DU particle. Moreover, it is now clear that there are marked genetic differences in the way individuals respond to radiation – with some being far more likely to develop cancer than others. So the fact that some veterans of the first Gulf war seem relatively unharmed by their exposure to DU in no way proves that DU did not damage others.

In 1996 and 1997 UN Human Rights Tribunals condemned DU weapons for illegally breaking the Geneva Convention and classed them as ‘weapons of mass destruction’ ‘incompatible with international humanitarian and human rights law’. Since then, following leukaemia in European peacekeeping troops in the Balkans and Afghanistan (where DU was also used), the EU has twice called for DU weapons to be banned.

Yet, far from banning DU, America and Britain stepped up their denials of the harm from this radioactive dust as more and more troops from the first Gulf war and from action and peacekeeping in the Balkan and Afghanistan have become seriously ill. This is no coincidence. In 1997, while citing experiments, by others, in which 84 percent of dogs exposed to inhaled uranium died of cancer of the lungs, Dr Asaf Durakovic, then Professor of Radiology and Nuclear Medicine at Georgetown University in Washington was quoted as saying, ‘The Veteran Administration asked me to lie about the risks of incorporating depleted uranium in the human body.’ He concluded, ‘uranium… does cause cancer, uranium does cause mutation, and uranium does kill. If we continue with the irresponsible contamination of the biosphere, and denial of the fact that human life is endangered by the deadly isotope uranium, then we are doing disservice to ourselves, disservice to the truth, disservice to God and to all generations who follow.’ Not what the authorities wanted to hear and his research was suddenly blocked.
