Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (u) in a sample: uranium-234 (234 u) and uranium-238 (238 u) it is one of several radiometric dating techniques exploiting the uranium radioactive decay series, in which 238 u undergoes 14 alpha and beta decay events on the way to the stable.
