The radiocarbon-14 dating method is a technique defining, with significant accuracy, the age of objects which were once mainly made of a living material. This method was introduced in 1946, when Willard F. Libby, within the context of researching cosmic rays, predicted the creation of the radioisotopic carbon-14 in the atmosphere. Soon, by utilizing the first indications and experiments, he proved the possibilities emerging from the use of the forementioned scientific procedure. He was awarded with the Nobel prize for Chemistry “for his method of applying the carbon-14 for the definition of age in Archaeology, Geology, Geophysics and other scientific disciplines”. Simplified information and data are presented in this article for the best understanding of this method.
