A second assumption is that the sample being dated has not experienced any loss or contamination of C over its history. At the core are extensive treatments of the radiocarbon dating technique and the history of its discovery by physicist Willard Libby and coworkers.…Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure. How scientists can use radioactive decay to find the age of certain materials. continue reading » Time-saving video on carbon dating.
