    "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.In theory, it could even be used to date the Shroud of Turin." Rowe explained that the new method is a form of radiocarbon dating, the archaeologist's standard tool to estimate the age of an object by measuring its content of naturally-occurring radioactive carbon.Scientists have developed a first-of-its-kind method for determining the age of ancient artifacts without causing damage to the objects.The method could help shed new light on the history of mummified bodies, old maps, cave paintings, and other treasures, they say.Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it.But there are many misconceptions about how radiocarbon works and how reliable a technique it is.The pretreatment of samples for radiocarbon measurements, transforming a variety of materials into graphite solid targets, represents a critical point in the accelerator mass spectrometry (AMS)procedure.

    The C-12 is a very stable element and will not change form after being absorbed; however, C-14 is highly unstable and in fact will immediately begin changing after absorption.Although it sometimes requires taking minute samples of an object, even that damage may be unacceptable for some artifacts.The new method does not involve removing a sample of the object.Scientists have developed a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.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.
