This dramatically improves accuracy, and reduces the amount of carbon required from about 10 grams to only a few milligrams.In recent years, dating methods based on cosmogenic isotopes other than carbon (such as beryllium-10 and chlorine-36) have been developed, which allow for the dating of a wider variety of objects over much longer time scales.Radiocarbon dating—also known as carbon-14 dating—is a technique used by archaeologists and historians to determine the age of organic material.It can theoretically be used to date anything that was alive any time during the last 60,000 years or so, including charcoal from ancient fires, wood used in construction or tools, cloth, bones, seeds, and leather.In this way, calibration tables have been developed that eliminate the discrepancy.Despite its usefulness, radiocarbon dating has a number of limitations.
