A little about the video
Carbon Dating:. Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but teachers should note that this technique will not work on older fossils like those of the dinosaurs which are over 65 million years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharohs among other things. What is Carbon?

Luminescence Dating in Archaeology

Carbon C , nonmetallic chemical element in Group 14 IVa of the periodic table. Although widely distributed in nature, carbon is not particularly plentiful—it makes up only about 0. In the isotope carbon was selected to replace oxygen as the standard relative to which the atomic weights of all the other elements are measured. Carbon , which is radioactive , is the isotope used in radiocarbon dating and radiolabeling. Only hydrogen , helium , oxygen , neon , and nitrogen are atomically more abundant in the cosmos than carbon.

Luminescence Dating

Radiocarbon dating—also known as carbon dating—is a technique used by archaeologists and historians to determine the age of organic material. It can theoretically be used to date anything that was alive any time during the last 60, years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather. It cannot be applied to inorganic material such as stone tools or ceramic pottery.

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.
