Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts…When we think of the last 50,000 years of prehistory, particularly the “Ice Age”, extinct species such as the woolly mammoth and woolly rhinoceros often spring to mind.
This discussion is a simplified introduction to radiocarbon dating.
C-12 and C-13 are stable but C-14 decays at a known rate, with a half-life of 5,568 years.
University of Leicester archaeologists took four small samples from one of the ribs of the Greyfriars skeleton and sent them to two specialist units with the facilities to analyse them: the Scottish Universities Environmental Research Centre (SUERC) at the University of Glasgow, and the Oxford Radiocarbon Accelerator Unit, part of the University of Oxford’s Research Laboratory for Archaeology and the History of Art.
Radiocarbon dating may only be used on organic materials.
Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.
It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.
Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.
There are exceptions to the theories and relationships introduced below that are beyond the scope of this discussion.
Carbon is the basis of life and is present in all living things.
But if they are earlier than 1485, then they can’t be Richard’s remains.
Radiocarbon dating is a commonly used technique which relies on the fact that, although 99% of carbon atoms have six protons and six neutrons (carbon-12), about 1% have an extra neutron (carbon-13) and about one atom in a trillion has two extra neutrons (carbon-14).
