New Innovation in Carbon Dating

According to Science Daily a new innovation in radiocarbon dating – or an extension of a previous method is being presented at the 239th National Meeting of the American Chemical Society.

According to Science Daily:

Rowe’s new method, called “non-destructive carbon dating,” eliminates sampling, the destructive acid-base washes, and burning. In the new method, scientists place an entire artifact in a special chamber with a plasma, an electrically charged gas similar to gases used in big-screen plasma television displays. The gas slowly and gently oxidizes the surface of the object to produce carbon dioxide for C-14 analysis without damaging the surface, he said.

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.

I’m still looking for more information…
