Radiocarbon dating measures radioactive isotopes in once-living organic material instead of rock, using the decay of carbon-14 to nitrogen-14.When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.Which illustrates that, contrary to popular belief, the dating methods are not the primary way that ages are decided. Their results are always ‘interpreted’ to agree with other factors, such as the evolutionary interpretation of geology and fossils.A technique for measuring the age of organic remains based on the rate of decay of carbon 14.
