Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay. Measuring the amount of 14 C in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calculate when the animal or plant died.

Radiocarbon dating is used to date obuhov.info - Professional Personal Trainer Association | PROPTA

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science. It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50, years ago - about when modern humans were first entering Europe. For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue. As explained below, the radiocarbon date tells us when the organism was alive not when the material was used. This fact should always be remembered when using radiocarbon dates. The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.

For years, the standard way to date ancient organic items for history was to use radiocarbon dating. It has been an important dating tool available to scientists and archaeologists who deal with organic matter regularly and are often required to date these items accurately to place them within context and timelines. Also called carbon dating or carbon dating, this method involves isolating the radioactive carbon within organic matter to determine the age of it. By locating the radioactive isotope carbon in organic matter, scientists could determine the age of an item.
