How Carbon Dating Works

What information does carbon dating provide

History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Before deciding on using carbon dating as an analytical method, an archaeologist must first make sure that the results of radiocarbon dating after calibration can provide the needed answers to the archaeological questions asked. Living organisms from today would have the same amount of carbon as the atmosphere, whereas extremely ancient sources that were once alive, such as coal beds or petroleum, would have none left. Aluminum containers with screw caps are safe, but it is still best to consult the radiocarbon laboratory for the best containers of carbon dating samples. The implication of what is represented by the carbon 14 activity of a sample must be considered. Levels of 14C are affected significantly only by the passage of time. The calculations involve several steps and include an intermediate value called the "radiocarbon age", which is the age in "radiocarbon years" of the sample: When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.

Among the first objects tested were samples of redwood and fir trees, the age of which were known by counting their annual growth rings. In other words, things that were living. In this method, the carbon 14 content is directly measured relative to the carbon 12 and carbon 13 present. Top of page The Keeling Curve The carbon cycle features prominently in the story of chemist Ralph Keeling, who discovered the steadily increasing carbon dioxide concentrations of the atmosphere.
