Radiocarbon dating of metal marilyn quayle dating
Until this century, relative dating was the only technique for identifying the age of a truly ancient object.
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.The originators of the theory reported a causal connection between the ...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 ...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.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.
"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.
