Chronometric Dating in Archaeology pp Cite as. Uranium decays through a number of radioactive daughter isotopes, some of which have half-lives comparable to the time scale of prehistoric archaeology. The growth of these isotopes in naturally occurring materials at archaeological sites can be used to determine the age of sites. The growth of Th from its parent, U, can be used over a time range from a few hundred to half a million years.

Uranium series: Any of the radioactive decay products produced from either of two long-lived isotopes of uranium U found in nature U and U resulting in a sequence of shorter-lived radioactive daughter isotopes that can be used to provide age information based on the well-characterized decay constants for each isotope in the decay series and the fact that they can be fractionated due to differences between their chemical or nuclear properties. Over the past few decades, uranium decay series has emerged as a fundamental tool for dating recent geological events with an extremely wide range of applications. There have been several recent reviews about the geochronological applications of these isotopic tools e.
