What is Carbon Dating? The age of archaeological specimens can be calculated by looking at the amount of carbon - 14 in a sample. The method is a form of radio dating called carbon dating. Radio dating can also be used to date rocks. How is Carbon - 14 formed? The isotope carbon - 14 is created at a constant rate in the upper atmosphere by cosmic rays acting on nitrogen. The carbon - 14 which is formed is radioactive and decays to produce nitrogen again.

Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14 C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists. By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age. However, many objects were found in caves, frozen in ice , or in other areas whose ages were not known; in these cases, it was clear that a method for dating the actual object was necessary.
