Today, most of the methods utilized for chronometric dating of fossils are radiometric. Radiometric dating, in general, refers to the dating of material by using the known rate at which certain radioactive isotopes decay, or at what rate there are collective changes due to radioactivity. Even though isotopes of an element can be different when it comes to atomic mass, the atomic number of the isotope is always the same. Radioactive elements decay at unique rates, dependant on the isotope. By measuring this decay, and knowing the half life of an element, scientists can date a sample. One of the most common forms of radiometric dating applied today is radiocarbon, or Carbon dating.

Radiocarbondatierung , ist ein Verfahren zur radiometrischen Datierung kohlenstoffhaltiger , insbesondere organischer Materialien. Der zeitliche Anwendungsbereich liegt zwischen und etwa Lebende Organismen sind von diesem Effekt nicht betroffen, da sie ständig neuen Kohlenstoff aus der Umwelt aufnehmen, der wieder den normalen Anteil an 14 C-Atomen einbringt. Entwickelt wurde die Radiokarbondatierung von Willard Frank Libby , [1] der für diese Leistung mit dem Nobelpreis für Chemie ausgezeichnet wurde. Die Radiokarbondatierung wird in der archäologischen Altersbestimmung , Archäobotanik und Quartärforschung angewandt. In der Natur kommen drei Isotope des Kohlenstoffs vor: Wenn die kosmische Strahlung auf Atome der Atmosphäre trifft, werden durch Spallation Neutronen freigesetzt.
