Carbon dating , also called radiocarbon dating , method of age determination that depends upon the decay to nitrogen of radiocarbon carbon Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle : it is absorbed from the air by green plants and then passed on to animals through the food chain. Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food. Once the organism dies, however, it ceases to absorb carbon, so that the amount of the radiocarbon in its tissues steadily decreases.

How Does Carbon Dating Work
Radiocarbon dating - Wikipedia
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.

Does carbon dating prove the earth is millions of years old?
Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things.
In the s W. Libby and others University of Chicago devised a method of estimating the age of organic material based on the decay rate of carbon Carbon dating can be used on objects ranging from a few hundred years old to 50, years old. Carbon is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms :.
