Because the half-life of carbon-14 is 5,700 years, it is only reliable for dating objects up to about 60,000 years old.
How long can you date carbon-14 samples?
The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
Would carbon-14 dating be appropriate for dating?
Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials (not applicable to metals).
