How abundant is uranium
WebIn natural uranium and in uranium ore, 234 U occurs as an indirect decay product of uranium-238, but it makes up only 0.0055% (55 parts per million) of the raw uranium because its half-life of just 245,500 years is only about 1/18,000 as long as that of 238 U. Thus the rate of 234 U to 238 WebUranium 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.
