Carbon-14 is used for radio dating of organic materials

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died. An isotope is a form of an element with a certain number of neutrons, which are the subatomic particles found in the nucleus of an atom that have no charge. While the number of protons and electrons in an atom determine what element it is, the number of neutrons can vary widely between different atoms of the same element. Nearly 99 percent of all carbon on Earth is Carbon, meaning each atom has 12 neutrons in its nucleus.

Carbon is a radioactive isotope used to date organic material. Its consistent rate of decay allows the age of an object to be determined by the proportion of carbon to other carbon isotopes. This process is called radiocarbon dating. Carbon is also used as a radioactive tracer for medical tests. Carbon dating works by comparing the amount of carbon in a sample to the amount of carbon Because organisms stop taking in carbon at death, the age of the material can be precisely determined by this ratio of carbon isotopes.

Radiocarbon, or Carbon, dating is probably one of the most widely used and best known absolute dating methods. It was developed by J. Arnold and W. Libby in , and has become an indispensable part of the archaeologist's tool kit since. It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences.
