Carbon dating metal

Radiocarbon dating is one of the most widely used scientific dating methods in archaeology and environmental science. It can be applied to most organic materials and spans dates from a few hundred years ago right back to about 50, years ago - about when modern humans were first entering Europe. For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue. As explained below, the radiocarbon date tells us when the organism was alive not when the material was used. This fact should always be remembered when using radiocarbon dates.

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. Traditional carbon dating involves removing and burning small samples of the object.
