Prior to the development of radiocarbon dating , it was difficult to tell when an archaeological artifact came from. Unless something was obviously attributable to a specific year -- say a dated coin or known piece of artwork -- then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item. The excavator might employ relative dating, using objects located stratigraphically read: buried at the same depth close to each other, or he or she might compare historical styles to see if there were similarities to a previous find. But by using these imprecise methods, archeologists were often way off.
Radiocarbon dating gets a postmodern makeover
December 15, by Russell Lee. I recently shared a story that included radiocarbon dating. By happy coincidence, December 17 is the birthday of Willard Libby , the American chemist who invented it. The element carbon exists in several different isotope forms carbon, carbon and carbon , depending on the number of neutrons in its atom. Carbon is constantly being formed in the atmosphere as cosmic rays interact with nitrogen gas, and it gets absorbed by every living thing on Earth.

How Carbon-14 Dating Works
British Broadcasting Corporation Home. Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon there is left in an object. In , he won the Nobel Prize for Chemistry. This is now the most widely used method of age estimation in the field of archaeology. Certain chemical elements have more than one type of atom.
Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine. Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive.
