Radiocarbon dating helped verify the authenticity of the Dead Sea scrolls.. Radiocarbon dating (also called carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of carbon-14 (radiocarbon, 14 C), a radioactive isotope of carbon.
The calculation of radiocarbon dates determines the age of an object containing organic material by using the properties of radiocarbon (also known as carbon-14), a radioactive isotope of carbon. Radiocarbon dating methods produce data based on the ratios of different carbon isotopes in a sample that must then be further manipulated in order to ...
C in the sample at the time the tree ring was formed – and hence the 14 C / 12 C ratio in the atmosphere at that time. [1] Armed with the results of carbon-dating the tree rings, it became possible to construct calibration curves designed to correct the errors caused by the variation over time in the 14 C / 12 C ratio.

Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date ...
Radiocarbon dating is also simply called carbon-14 dating. Carbon-14 is a radioactive isotope of carbon, with a half-life of 5,730 years [ 28 ] [ 29 ] (which is very short compared with the above isotopes), and decays into nitrogen. [ 30 ]
Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.
The Hallstatt plateau or the first millennium BC radiocarbon disaster, as it is called by some archaeologists and chronologists, [1] is a term used in archaeology that refers to a consistently flat area on graphs that plot radiocarbon dating against calendar dates.
Samples used for radiocarbon dating must be handled carefully to avoid contamination. Not all material can be dated by this method; only samples containing organic matter can be tested: the date found will be the date of death of the plants or animals from which the sample originally came.
