What are the different types of carbon dating

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.

Gamma radiation releases the most energy, followed by Beta and then Alpha. It takes a few inches of solid lead to block Gamma rays. When atoms decay, they emit three types of radiation, alpha, beta and gamma. The alpha and beta radiation consist of actual matter that shoots off the atom, while gamma rays are electromagnetic waves. All three kinds of radiation are potentially hazardous to living tissue, but some more than others, as will be explained later on.

British Broadcasting Corporation Home. Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon there is left in an object. In , he won the Nobel Prize for Chemistry. This is now the most widely used method of age estimation in the field of archaeology.
Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14 C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists. By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age.
