New Method Could Revolutionize Dating of Turin Shroud
by Rossella Lorenzi
Wednesday, March 24, 2010

"In the case of the shroud of Turin, we would roll the cloth into as tight a package as we can make it," Rowe said.

The Turin shroud already underwent carbon-14 dating in 1988. At that time, three reputable laboratories in Oxford, Zurich and Tucson, Ariz., concluded that the cloth on which the smudged outline of the body of a man is indelibly impressed was a medieval fake dating from 1260 to 1390, and not the burial cloth wrapped around the body of Christ.

However, the radiocarbon dating did not prevent many scholars from formulating various hypotheses over the validity of the carbon-14 tests, including the possibility that they were conducted on a sample taken from a medieval patch.

Rowe's method could finally put aside such speculation since it could place the date for the entire shroud.

Nobody bring up the dinosaurs dep’t — I know it’ll come up, so:

[snp] Radioactive carbon, produced when nitrogen 14 is bombarded by cosmic rays in the atmosphere, drifts down to earth and is absorbed from the air by plants. Animals eat the plants and take C14 into their bodies. Humans in turn take carbon 14 into their bodies by eating both plants and animals. When a living organism dies, it stops absorbing C14 and the C14 that is already in the object begins to disintegrate. Scientists can use this fact to measure how much C14 has disintegrated and how much is left in the object. Carbon 14 decays at a slow but steady rate and reverts to nitrogen 14. The rate at which Carbon decays (Half-life) is known: C14 has a half-life of 5730 years. Basically this means that half of the original amount of C14 in organic matter will have disintegrated 5730 years after the organisms death; half of the remaining C14 will have disintegrated after another 5730 years and so forth. After about 50,000 years, the amount of C14 remaining will be so small that the fossil can’t be dated reliably. [nsnp]

There’s nothing that could convince some folks here that the earth is over 10,000 years old.

They were conducted on a sample taken from a medieval patch. I wonder what this technique would do to other evidence such as pollen. Wash it away?
