Radiometric ages of about a million years older than the rest of the meteorite dating my cousin's daughter muziek Carbon dating is used to determine the age of biological artifacts. The short half-life of carbon-14 means it cannot be used to date fossils that are allegedly cannot give an exact age of the item. Radiometric dating methods give absolute ages ranging from decades to isotope has a characteristic, fixed, half-life. How are the age of rocks determined? How old is planet Earth? Ex: radiometric dating (# of half-lives)(known half-life of radioactive isotope) = Age of object RADIOMETRIC DATING: Age of substence based Radioactive decay.
