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.

Explainer: what is radiocarbon dating and how does it work?

Carbon dating , also known as radiocarbon dating, is a scientific procedure used to date organic matter. It depends upon the radioactive decay of carbon 14 C , an unstable isotope of carbon which is continually synthesized in the upper atmosphere by cosmic rays. Plants take up atmospheric 14 C for as long as they live, through the process of photosynthesis. Animals take up atmospheric 14 C indirectly, by eating plants or by eating other animals that eat plants.
