Alternatives to radio carbon dating
Rowe hopes to use it, for instance, to analyze objects such as a small ivory figurine called the "Venus of Brassempouy," thought to be about 25,000 years old and one of the earliest known depictions of a human face.The figurine is small enough to fit into the chamber used for analysis.
One popular theory about the Paleolithic cave paintings proposes that sites were chosen based on the acoustics in the caves.
"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.
Rowe and his colleagues used the technique to analyze the ages of about 20 different organic substances, including wood, charcoal, leather, rabbit hair, a bone with mummified flesh attached, and a 1,350-year-old Egyptian weaving.
The results match those of conventional carbon dating techniques, they say.
