How radioactive is carnotite
NettetUranium ore refers to naturally occurring rock or mineral deposits that contain a sufficient concentration of uranium, a radioactive element, to make its extraction economically viable. Uranium is a relatively rare element and is typically found in trace amounts in the Earth's crust.
