Ancient Uranium Mining In Libya
Sep 19, 2019 The proportion of uranium-235 relative to uranium-238 in an ore has been changing since the earth formed because uranium is radioactive and decays to other elements over time. Uranium-238 decays at a much slower rate it has a half-life of 4.5 billion years than uranium-235 half-life of 700 million years, so uranium-235 was ...
