Radiocarbon 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.
Carbon dating , or carbon dating, is a method for comparing the ages of organic materials such as bones or artifacts made from anything that once lived. Unlike many other radiometric dating methods, carbon dating has been calibrated for historical periods and within that range can give reliable results. The technique is based on comparing the levels of 14 C and 12 C isotopes in the sample.
