What is carbon dating wikipedia

Carbon 14C is unstable, and degrades exponentially over time. When an organism dies, the intake of 14C ceases, and what was left in the organism begins a measurable disintegration. This analysis provides a radiocarbon age of the sample, which must then be calibrated in accordance with a radiocarbon dating calibration curve such as the one pictured below.

A variety of factors have caused the amount of 14C present in the atmosphere to vary over time, resulting in deviations between the age predicted by radiocarbon dating and the absolute date of a specimen. Carbon dating produces the most reliable results when multiple samples can be tested to ensure accuracy and limit potential interferences.

Alternative dating techniques such as dendrochronology may be employed to confirm the results of radiocarbon dating. I was always curious about the carbon dating.

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.

Carbon dating is something that you hear about in the news all the time. Find out how carbon dating works and why carbon dating is so accurate! Because deep-sea cores reveal that carbon dioxide levels are much higher today than at any time in the past 15 million See “Radiocarbon Dating,” Wikipedia.
