238U decay chainalpha decaydecay datanuclear datahalf-livesNon-neutron nuclear data (half-lives, transition intensities, radiation energies and emission probabilities) have been re-evaluated for the radionuclides that constitute the decay chain of uranium-238 on the basis of new absolute measurements ...
238U decays to stable206Pb via a series of α and β decays. If the decay chain is undisturbed, it reaches a steady state called secular equilibrium, and the abundance of short-lived intermediate nuclides is then controlled by their half-lives. However, this secular equilibrium can be perturbe...
An example is the natural decay chain of Uranium-238 which decays, through alpha-emission, with a half-life of 4.5 billion years to Thorium-234, which decays, through beta-emission, with a half-life of 24 days to Protactinium-234, which decays, through beta-emission, with a half-life of...

Related to Decay series:uranium decay series decay chain n. A sequence of radioactive decay processes in which the decay of one element creates a new element that may itself be radioactive, and continuing until the sequence ends with stable, nonradioactive atoms. ...
Non-neutron nuclear data (half-lives, transition intensities, radiation energies and emission probabilities) have been evaluated for the radionuclides constituting the decay chain of uranium-238. A selection of the many recommended data are presented that may be useful in several applications (e.g. ...

Radioactive decayof Uranium and Thorium isotopes at constant rates provides a tool to determine the age ofspeleothemswith high precision and accuracy. As with any dating method a fundamental prerequisite is the lack of post-depositional alteration, that is, no gain or loss of isotopes within the...
