Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock.As uranium decays radioactively, it becomes different chemical elements until it stops at lead.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.The uranium and thorium decay systems offer a multitude of radiometric dating options.

Therefore, without accurately known decay half-lives, all radioisotope ages cannot be accurately determined or be considered absolute ages.

The reason for stopping at lead is because lead is not radioactive and will not change into a different element.

It may sound straight-forward, but there are many variables that have to be considered.

U decay constants and half-lives have been made using direct counting experiments and geological age comparisons, as well as by critical reviews and reevaluations of those determinations. “Natural Reactor Studies.” In Uranium in the Pine Creek Geosyncline.

By 1971 the direct counting experiments had provided U half-life values with small uncertainties which ever since have been the recommended values used in all U-Pb age calculations.

Uranium comes in two common isotopes with atomic weights of 235 and 238 (we'll call them 235U and 238U).
