But even he “realized that there probably would be variation”, says Christopher Bronk Ramsey, a geochronologist at the University of Oxford, UK, who led the latest work, published today in Science.Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.
Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.
And if the artifact is organic—like wood or bone—researchers can turn to a method called radiocarbon dating.
In it, Rodger Sparks, a carbon dating expert from New Zealand, and William Meacham, archaeologist and Shroud researcher from Hong Kong, debated some of the theories that have been proposed regarding possible inaccuracies in the 1988 carbon dating test results.
Anyone who still believes that C14 dating has proven the Shroud to be medieval should be quickly disabused of that notion.
Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
