How is uranium extracted from the earth
WebThere are 27 known isotopes of uranium ranging in atomic weights 217–219, 222–240 and 242, with half-lives of from billions of years to a few nanoseconds. Naturally occurring uranium consists of three major isotopes: 238 U (99.28% abundance), 235 U (0.71%), and 234 U (0.0054%). WebUranium is an element which exists naturally in the Earth’s crust; specifically in sedimentary rocks, such as sandstone. In its elementary state uranium is only weakly radioactive due …
