Fractionation dating method
An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.
The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.
American physical chemist Willard Libby led a team of scientists in the post World War II era to develop a method that measures radiocarbon activity.
Background samples analyzed are usually geological in origin of infinite age such as coal, lignite, and limestone.Standard errors are also reported in a radiocarbon dating result, hence the “±” values.These values have been derived through statistical means.It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.
