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.

We can indirectly date glacial sediments by looking at the organic materials above and below glacial sediments. Radiocarbon dating provides the age of organic remains that overly glacial sediments. It was one of the earliest techniques to be developed, during the s.
This essay will consider both the inherent strengths and weaknesses of Radiocarbon dating and Dendrochronology, and also the ways in which these techniques can be applied inappropriately. As might be expected, each of the techniques has limitations and conditions under which it can be applied; it is when the technique is applied to conditions outside these limitations, perhaps for reasons of interpretative determinism, that the integrity of the technique is undermined. Additional to these factors could be a multitude of other considerations not strictly properties of the technique itself. For example, the processes by which the technique is performed and the associated skills and knowledge required to produce accurate determinations will necessarily impact the availability of the technique, but availability and the associated monetary cost is not an intrinsic property of the technique itself.
