Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, radiocarbon dating invention the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: inhe won a Nobel Prize in Chemistry for the invention. It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not. Shy of a date stamp on an object, it is still the best and most accurate of dating techniques devised.
Radiocarbon dating is the use of radiocarbon dating invention naturally occurring isotope of carbon in radiometric dating to determine the age of organic materialsup to ca. Within archaeology it is considered an absolute dating technique. Carbon has two stable isotopes: carbon 12 Cand carbon 13 C. In addition, there are tiny amounts of the unstable radioactive isotope carbon 14 C on Earth.

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.
