In dating: Fission-track dating …during the spontaneous fission of uranium-238. In this unique type of radioactive decay, the nucleus of a single parent uranium atom splits into two fragments of similar mass with such force that a trail of crystal damage is left in the mineral. The Uranium 238 Dating Method. By Paul Nethercott.

2019-02-10 · In a 704-million-year-old rock, 235U is at its half-life and there will be an equal number of 235U and 207Pb atoms (the Pb/U ratio is 1). In a rock twice as old there will be one 235U atom left for every three 207Pb atoms (Pb/U = 3), and so forth. With 238U the Pb/U ratio grows much more slowly with age, but the idea is the same.
