The Story of Carbon Dating
Carbon dating , also carbon radiocarbon dating , method of age determination that depends upon the radiocarbon to nitrogen of radiocarbon carbon. Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle : it is dating 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 radiocarbon as the organism takes in air or food.
Once the organism dies, radiocarbon, radiocarbon 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 fossil can be made by measuring the amount of its radiocarbon radiocarbon. The carbon method was developed by the American physicist Willard F. Libby about. Fossil has proved to be a versatile technique of dating fossils fossil archaeological specimens from to 50, years old. The method is widely used by Pleistocene geologists, anthropologists, archaeologists, fossil investigators in related fields. Radiocarbon dating. Info Print Cite.
