WebApr 16, 2024 · Absolute dating or radiometric dating is a method used to determine the age of rocks by measuring its radioactive decay. A radioactive isotope in the rock decays into a stable daughter isotope. The decay occurs at a predictable rate, so the age of the sample could be determined. WebJan 6, 2011 · Radiometric dating is a technique that uses the change of one isotope, the parent, to another, the daughter, to determine the amount of time since the decay began. Carbon-14 is supposed to allow dating of objects up to 60,000 years.
