The results match those of conventional carbon dating techniques, they say.The chamber could be sized to accommodate large objects, such as works of art and even the Shroud of Turin, which some believe to be the burial cloth of Jesus Christ, Rowe said.The gas slowly and gently oxidizes the surface of the object to produce carbon dioxide for C-14 analysis without damaging the surface, he said.

Rowe's new method, called "non-destructive carbon dating," eliminates sampling, the destructive acid-base washes, and burning.

In the new method, scientists place an entire artifact in a special chamber with a plasma, an electrically charged gas similar to gases used in big-screen plasma television displays.

Under the Paris Agreement on climate change, the world committed to prevent global warming from going above 2C but also attempt to restrict it to as close as 1.5C as possible amid mounting evidence that dangerous effects could kick in sooner than previously thought.

The new study, described in a paper in the journal , is one of the first to use the new Feli X computer model, which includes social and economic factors along with environmental ones.

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.The figurine is small enough to fit into the chamber used for analysis.Funding for this project is provided by the National Science Foundation, the National Center for Preservation Technology and Training, and Texas A&M University.A geologist, accustomed to putting his lab’s high-tech nanoscale scanning electron microscope (nano SEM) to work evaluating the mineral composition of rocks and meteorites, has now been enlisted for ...
