Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts.

What is radioactive dating used for?

Dr Fiona Petchey is using carbon C to date artefacts of historical importance excavated from the Wairau Bar archaeological site in Blenheim. However, pre samples that are less than years old or older than 60, years cannot be accurately dated. The reason for this has to do with the concentration of C in living materials as well as the half-life of the C isotope. Atomic bomb detonations since have boosted the amount of C in the atmosphere and, as a result of this, a method has been devised to date recent samples. Once formed, the C reacts with oxygen to form 14 CO 2.

Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale.
