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 th 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. 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.
Radiometric dating - Wikipedia
Social Science. The approximate age of ancient artifacts can be determined as long as the artifact is not older than 50, years. This would be wood, plants, animals and of course humans. Carbon is used for dating because it is radioactive and considered unstable. They collide with the N atoms and convert them into C atoms. This collision changes a proton into a neutron. The C then combines with oxygen to form carbon dioxide, CO

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon
On the Atlantic coast of the U. In Morocco, paleontologists excavated the fossils of a dinosaur that roamed Earth million years ago. How did the researchers determine these ages?
