CG: n CT:  Carbon-14 dating Radiocarbon dating, or carbon-14 dating, is a method for determining the age of a substance containing organic molecules by using the properties of radiocarbon, 14C, a radioactive isotope of carbon. The technique was developed in the late 1940s at the University of Chicago by Willard Libby,

CG: n CT: Carbon is the main element of all biological processes. Natural carbon consists predominantly of the stable isotope 12C. The isotopes 10C and 11C have half-lives, 19 s and 20.5 min, respectively, and half-life of 14C is 5730 years. At its decay, 14C emits only beta particles with the
