Radiocarbon dating is a popular method used by archaeologists and scientists to determine the age of organic materials. However, radiocarbon can also be referred to as carbon dating, carbon-14 dating, or 14C dating. These synonyms all pertain to the same method, which involves measuring the levels of carbon-14 in a sample to determine its age. Other variations of radiocarbon dating include accelerator mass spectrometry (AMS) dating and potassium-argon (K-Ar) dating. While radiocarbon dating is most commonly associated with archaeology, it can also be used in geology, biology, and other scientific fields to date a variety of organic materials.
