How does carbon dating work
Reporting at the 239th National Meeting of the American Chemical Society (ACS), they said it could allow scientific analysis of hundreds of artifacts that until now were off limits because museums and private collectors did not want the objects damaged."This technique stands to revolutionize radiocarbon dating," said Marvin Rowe, Ph. "It expands the possibility for analyzing extensive museum collections that have previously been off limits because of their rarity or intrinsic value and the destructive nature of the current method of radiocarbon dating.All the while they have to keep their skin wet to enable oxygen absorption.Scientists have developed a first-of-its-kind method for determining the age of ancient artifacts without causing damage to the objects.Rowe's new method, called "non-destructive carbon dating," eliminates sampling, the destructive acid-base washes, and burning.
paper, the researchers wrote: “Roughly speaking, and based on current technologies, energy sector emissions will need to peak within the next decade.
Comparing the C-14 levels in the object to levels of C-14 expected in the atmosphere for a particular historic period allows scientists to estimate the age of an artifact.
Both the conventional and new carbon dating methods can determine the age of objects as far back as 45,000 to 50,000 years, Rowe said.
One of the researchers, Dr Michael Obersteiner, of the International Institute for Applied Systems Analysis near Vienna, said: “The Feli X model ...
provides a unique systemic view of the whole carbon cycle, which is vital to our understanding of future climate change and energy.
