What Is the Half-Life of Uranium?
 · Uranium-238, the most prevalent isotope of uranium, has a half-life of 4.46 billion years. This means that in 4.46 billion years, only half of the uranium would have decayed. Uranium-235 and Uranium-234 have half-lives of 704 million and 245,000 years, respectively.

Half-Life of Uranium (234)
Abstract The half-life of U 234 has been determined by two independent methods. The first method involves a re-measurement of the relative isotopic abundance of U 234 and U 238 in normal uranium; from this measurement the half-life of U 234 can be obtained in terms of the known half-life of U 238..
