Chris Prior from GNS Science explains radiocarbon dating, a method used to determine the age of organic materials by measuring the decay of carbon-14. The process involves preparing samples, converting them to graphite, and measuring them in an accelerator. The video covers suitable materials for dating, the limitations of the method, and the steps involved in sample preparation and measurement. The results are calibrated to provide a calendar age range, helping to verify the authenticity of historical artifacts.
