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.

There's quite a few, all of which are types of radioactive dating. They include potassium-argon dating, that's useful for rocks over , years old. There's also uranium-lead dating, which has an age range of It can be used for such long time spans because the half-life of uranium turning into lead is billions of years, in the order of the age of the Earth at 4. Mike, from Cambridge, also called in to remind us about thermo-luminescence which can be used in pottery, also obsidian hydration and uranium trail dating when you observe the trails left behind by uranium decomposition.

Is Carbon Dating Accurate?

Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: in , he won a Nobel Prize in Chemistry for the invention.

Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark -- calling into question historical timelines. Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions.
