Depleted Uranium (DU) is a highly toxic and mildly (although some people say not so mild!) radioactive substance, which is a by-product that is produced when Uranium is being turned into fuel for both nuclear power stations, and for nuclear bombs. Whilst this kind of 'clean' waste uranium is found in high amounts in DU bombs, there is a constant argument over just how much reprocessed spent nuclear reactor fuel is being packed into DU bombs too. And this is a big issue, because if reprocessed uranium is present in DU, it may be considered much more dangerous to humans, with higher levels of radioactivity present, plus the possible inclusion of other harmful substances, which were produced/used during the original nuclear fission process.

There is a long list of health effects, birth defects and cancers which have been associated with exposure to high levels of uranium, including so-called 'Gulf War Syndrome' - DU is thought to be the singular cause of this condition. The most recent known bulk uses of DU internationally, are by Coalition and NATO forces, with DU dropped over places like Iraq, Afghanistan and the Balkans, contaminating the land and population for hundreds, if not millions, of years. If the radioactivity levels are as expected in some DU bombs - high and dangerous to human beings, to other living things and to the environment - then western forces must be stopped from using them immediately. And furthermore, instead of dropping our DU waste over invaded countries, we must find ways to store it safely, or else we must stop producing it. For the sake of our survival, we also need to clean up the nuclear waste which we have dumped underwater and underground.
