The key difference between carbon dating and uranium dating is that carbon dating uses radioactive isotopes of carbon, whereas uranium dating uses uranium , which is a radioactive chemical element. Carbon dating and uranium dating are two important methods of determining the age of different organic materials. We call them isotopic dating methods. The oldest method among them is Uranium-Lead dating method.

The Carbon 14 Myth

Carbon - Wikipedia

Carbon dating , known also as radiocarbon dating , is a method for determining the age of an object containing organic material by using the properties of radionuclide carbon In spite of this short half-life compared to the age of the earth, carbon is a naturally occurring isotope. Its presence can be explained by the following simple observation. Our atmosphere contains many gases, including nitrogen

Radiocarbon dating

Carbon 14 C , or radiocarbon , is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues to date archaeological, geological and hydrogeological samples. Its existence had been suggested by Franz Kurie in The primary natural source of carbon on Earth is cosmic ray action on nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide. However, open-air nuclear testing between and contributed to this pool.
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 As a result, animal and plant life regularly assimilate carbon 14 atom together with the usual carbon 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.
