Radiocarbon Dating Counting carbon 14 atoms in a bygone object to find its age The most common of the radioactive dating techniques currently in use involves the isotope 14 of carbon, the radiocarbon. This radioactive isotope of carbon is present in the atmosphere in trace amounts, and in chemical processes is indistinguishable from normal carbon 12. As a result, animal and plant life regularly assimilate carbon 14 atom together with the usual carbon 12. The carbon 14 present in the atmosphere is constantly renewed. The cosmic rays originating from the Sun collide with nuclei in the upper atmosphere and are capable of breaking off individual neutrons.

Print Radiocarbon Dating and Archaeology Radiocarbon dating lab scientists and archaeologists should coordinate on sampling, storage and other concerns to obtain a meaningful result. The sample-context relationship must be established prior to carbon dating. The radiocarbon dating process starts with measuring Carbon-14, a weakly radioactive isotope of Carbon, followed by calibration of radiocarbon age results to calendar years. History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.
