The age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to closure temperature. Wetherill has shown that the two points on the Concordia curve intersected by this straight line will represent the time of initial crystallization and the time of the subsequent lead loss. After one half-life has elapsed, dating uranium, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay dating uranium.

Uranium-Lead Dating Ages determined by radioactive decay are always subject to assumptions about original concentrations of the isotopes. The natural radioactive series which involve lead as a daughter element do offer a mechanism to test the assumptions. Of all the isotopic dating methods in use today, the uranium-lead method is the oldest and, when done carefully, the most reliable. Unlike any other method, uranium-lead has a natural cross-check built into it that shows when nature has tampered with the evidence. uranium dating.
