how much of the world's uranium does australia have?
6. 9 %
normal functioning of the kidney, brain, liver, heart, and other systems can be affected by uranium exposure, because, besides being weakly radioactive, uranium is a toxic metal. uranium is also a reproductive toxicant. radiological effects are generally local because alpha radiation, the primary form of u decay, has a very short range, and will not penetrate skin. alpha radiation from inhaled uranium has been demonstrated to cause lung cancer in exposed nuclear workers. uranyl () ions, such as from uranium trioxide or uranyl nitrate and other hexavalent uranium compounds, have been shown to cause birth defects and immune system damage in laboratory animals. while the cdc has published one study that no human cancer has been seen as a result of exposure to natural or depleted uranium, exposure to uranium and its decay products, especially radon, are widely known and significant health threats. exposure to strontium-90, iodine-131, and other fission products is unrelated to uranium exposure, but may result from medical procedures or exposure to spent reactor fuel or fallout from nuclear weapons.
uranium
around 99.284% of natural uranium is uranium-238, which has a half-life of 1.41×10 seconds (4.468×10 years, or 4.468 billion years). depleted uranium has an even higher concentration of the u-238 isotope, and even low-enriched uranium (leu), while having a higher proportion of the uranium-235 isotope (in comparison to depleted uranium), is still mostly u-238. reprocessed uranium is also mainly u-238, with about as much uranium-235 as natural uranium, a comparable proportion of uranium-236, and much smaller amounts of other isotopes of uranium such as uranium-234, uranium-233, and uranium-232
