It is a method to determine the age of an object by using radiocarbon properties. In 1949, Willard Libby proposed carbon dating, a method for dating carbon-containing objects (like wood, leather, or cloth) that exploits the radioactive decay of carbon-14. 3 This is a means of determining the age of certain wood and plant remains, and hence of animal or human bones or artifacts found buried at the same levels. Radiocarbon dating is based on the fact that some wood or plant remains contain residual amounts of carbon-14, a radioactive isotope of carbon. It became an extremely valuable tool for archaeologists, paleontologists, anthropologists, and other fields that dealt with ancient artifacts.
