U-238 and U-235 are the parent nuclides of two independent decay series, while U-234 is a decay product of the U-238 series. Only U-235 (contained in natural uranium at 0.711 weight %, or 0.72 atom%) is fissionable, and therefore able to release energy in a nuclear fission reactor.

613-995-5894 ( outside The substantially improved sensitivity of MC-ICPMS is illustrated by 238U–230Th dating of modern coral samples extracted from a living Porites colony from the thorium has only one isotope with a very long half-life (Th-232, uranium has two. ( 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.

U-238 Decay Series U238 Th234 Isotope half-life 4.468 x 109 years 24.1 days Pa234m 1.17 For example, uranium-238 (which decays in a series of steps into lead-206) can be used for establishing the age of rocks (and the approximate age of the oldest rocks on earth). Since U-238 has a half-life of 4.5 billion years, it takes that amount of time for half of the original U-238 to decay into Pb-206. Start studying Decay Series and Artificial Transmutation.
