  1. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
    en.wikipedia.org/wiki/Radiocarbon_dating
    In short, radiocarbon dating is a technique to measure the amount of carbon 14 (C14) isotope present in an organic sample (a seed, bone, or even piece of wood) to estimate how long ago that sample died or began to decompose.

    In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon. Known as radiocarbon dating, this method provides objective age estimates for carbon-based objects that originated from living organisms.

    Radiocarbon dating, or carbon-14 dating, is a scientific method that can accurately determine the age of organic materials as old as approximately 60,000 years. First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon-14 isotope.

    Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. It can be used on objects as old as about 62,000 years.

    The concept of radiocarbon dating relied on the ready assumption that once an organism died, it would be cut off from the carbon cycle, thus creating a time-capsule with a steadily diminishing carbon-14 count.

    Professor Willard Libby, a chemist at the University of Chicago, first proposed the idea of radiocarbon dating in 1946. Three years later, Libby proved his hypothesis correct when he accurately dated a series of objects with already-known ages. For nearly 70 years, archaeologists have been measuring carbon-14 levels to date sites and artifacts.

    Users may also refer to the IntCal calibration database, in which all data submitted to IntCal are publicly available 8. Radiocarbon dating is destructive and requires a certain amount of carbon, so careful consideration should be given before analysis of very rare or high-value materials.

    The ongoing decline is due mainly to increased fossil-fuel emissions, which contain carbon but no 14 C. This has consequences for radiocarbon dating. Radiocarbon dating in archaeology, for example, is based on the decay of 14 C over time. A low value for 14 C/C in recently formed materials could therefore incorrectly imply that these are aged.
