What does radiocarbon dating mean

Radiocarbon dating was invented in the late s, and in the many decades since, archaeologists have discovered wiggles in the radiocarbon curve—because atmospheric carbon has been found to fluctuate over time. Adjustments to that curve to correct for the wiggles "wiggles" really is the scientific term used by the researchers are called calibrations. Radiocarbon dating is one of the best known archaeological dating tools available to scientists, and most people have at least heard of it. But there are a lot of misconceptions about how radiocarbon works and how reliable a technique it is; this article will attempt to clear them up. All living things exchange the gas Carbon 14 abbreviated C 14 , 14C, and, most often, 14 C with the environment around them—animals and plants exchange Carbon 14 with the atmosphere, while fish and corals exchange carbon with dissolved 14 C in sea and lake water. Throughout the life of an animal or plant, the amount of 14 C is perfectly balanced with that of its surroundings.

A method of estimating the age of an artifact or biological vestige based on the relative amounts of the different isotopes of carbon present in a sample. Radiocarbon dating is a technique that uses the decay of carbon to estimate the age of organic materials, such as wood and leather, up to about 58, to 62, years. Carbon dating was presented to the world by Willard Libby in , for which he was awarded the Nobel Prize in Chemistry. The dating method is based on the fact that carbon is found in various forms, including the main stable isotope and an unstable isotope. Through photosynthesis, plants absorb both forms from carbon dioxide in the atmosphere.
