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.. The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960

Image 1 illustrates the IntCal 2013 atmospheric radiocarbon calibration curve as related to standard radiocarbon age (Reimer et al., 2013). If not for factors influencing radiocarbon production and cycling, the curve would be a straight line. Image 1. The IntCal 13 radiocarbon calibration curve. Image taken from https://c14.arch.ox.ac.uk/oxcal/OxCal.html Hence, a single NH 14 C calibration curve (IntCal), constructed mainly from known-age wood from central and northern Europe and North America, has become the basis for calendar dates for pre- and protohistory and for other work requiring an accurate absolute time scale (1-4). This calibration curve is assumed as relevant for everywhere in the midlatitudes of the NH, including the Mediterranean, home of Old World prehistory. Intercomparisons between laboratories invariably indicate. The IntCal working group, which is responsible for internationally agreed radiocarbon data for calibration curves was led by Paula Reimer here at QUB.
