Mining of uranium and thorium
Mining of uranium and thorium today is not that much different from mining any other metal; the uranium itself generally has a very low level of radioactivity. Many uranium mines, especially in Australia and Canada, have ISO 14001 certification, which means they have adopted a set of international standards clarifying best practices for monitoring safety for workers and the environment.
Three-quarters of the world's uranium is mined in Kazakhstan, Canada, Australia and Namibia, with the remainder from another eleven countries.
Often, uranium is now being extracted by in situ leach methods, especially in the USA and Kazakhstan. This method of extraction is cheaper and also is widely seen as better environmentally than traditional mineral extraction methods such as those used in coal mining
