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. Because carbon decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

A technique for measuring the age of organic remains based on the rate of decay of carbon Because the ratio of carbon 12 to carbon 14 present in all living organisms is the same, and because the decay rate of carbon 14 is constant, the length of time that has passed since an organism has died can be calculated by comparing the ratio of carbon 12 to carbon 14 in its remains to the known ratio in living organisms.

A Closer Look In the late s, American chemist Willard Libby developed a method for determining when the death of an organism had occurred. He first noted that the cells of all living things contain atoms taken in from the organism's environment, including carbon; all organic compounds contain carbon.

Most carbon consists of the isotopes carbon 12 and carbon 13, which are very stable. A very small percentage of carbon, however, consists of the isotope carbon 14, or radiocarbonwhich is unstable. Through photosynthesis, plants absorb both forms from carbon dioxide in the atmosphere.
