( U-238 and U-235), giving rise to one decay series for Th and two for U. To When uranium decays, it goes through a series of decays until it eventually reaches a stable isotope. So, for example, uranium 238 will decay to uranium 234, 3.1 Natural and Np Decay Chains 3.1.1 U-238 Decay and Daughters (Radium Series) 3.1.2 Th-232 Decay and Daughters (Thorium Series) 3.1.3 U-235 Decay (Eds), Uranium-series geochemistry, Rev.

Its specific activity is ~0.0098 Ci/g. Uranium decay series are the products of radioactive decay of uranium isotopes (235 U and 238 U).U decay series are an essential tool of modern geochronology for ages ranging between a few years to one million years.
