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.

Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.

A man called Willard F Libby pioneered it at the University of Chicago in the 50's. This is now the most widely used method of age estimation in the field of archaeology.

Theoretically, if one could detect the amount of carbon-14 in an object, one could establish that object’s age using the half-life, or rate of decay, of the isotope.

In 1946, Libby proposed this groundbreaking idea in the journal Physical Review.

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.

After archaeologists have excavated the site completely, or to the extent the project planned, they fill the site back in and take the artifacts to be analyzed.A datum is a fixed reference point, often one placed by the U. The context of the artifact is just as important as the artifact itself, so the artifacts are always carefully mapped and documented.Archaeologists also look for features while excavating a site.A feature is evidence of a human activity that is not movable, and usually has a vertical component.An aspect of a site that is only horizontal, such as a road, is not a feature.
