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.

Radiocarbon dating - Wikipedia

The use of carbon, also known as radiocarbon, to date organic materials has been an important method in both archaeology and geology. The technique was pioneered over fifty years ago by the physical chemist Willard Libby, who won the Nobel Prize for his work on 14 C. Since then, the technique has been widely used and continually improved. This paper will focus on how the radiocarbon dating method works, how it is used by scientists, and how creationists have interpreted the results.

Radiocarbon dating

Charcoal and wood are two of the most widely used materials for accelerator mass spectrometry AMS radiocarbon dating. AMS labs prefer to carbon date charcoal and wood because these materials do not need complex pretreatment. Willard Libby, the pioneer of radiocarbon dating , identified charcoal to be the most reliable material to carbon date. The time-width of an organism refers to its total growth and exchange period with the biosphere. The time-width affects the way radiocarbon age is converted into calendar age for a sample.

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.

It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences.
