Carbon dating shroud turin
[Correction: reader Dan Porter from the website called to my attention that the original article incorrectly cited a 2005 paper published by Benford and Marino.
I am an Australian evangelical Christian in my 70s. Which is about the length of the Ninety Mile Beach in Victoria, Australia, only a part of which is shown right. M., 2012, "New Photographs of Arizona Radiocarbon Dating Laboratory Samples," Shroud.com, November 21.
We can allow that based on this new evidence, we can assert that we believe the shroud is authentic, but we cannot claim to it’s real.
Between May and August 1988, three radiocarbon dating laboratories at universities in Arizona, Zurich and Oxford, all using the same new Accelerator Mass spectrometry (AMS) method, radiocarbon dated samples that had been cut from the Shroud on 21 April 1988. Oxford laboratory did find some old cotton threads in their sample, but they were only "two or three fibres". Hall estimated that it would require "65 per cent of the mass of the shroud ...
At a press conference in the British Museum, on 13 October 1988, following leaks that the Shroud had been dated "1350", Prof. to give a date of 1350 to a fabric originally dating from the time of Christ" but there was "less than 0.1 per cent" of such contamination in the Shroud (my emphasis).

Instead, Rogers found powerful evidence suggesting Benford and Marino had been absolutely correct in saying the material for the original carbon dating tests had been taken from a contaminated section of the shroud, identifying cotton fibers in the sample not found in the rest of the shroud.
He proposed testing the scorch marks on the shroud for more accurate carbon dating.
The new tests have recently been performed, putting the shroud in the right time frame so that it could be authentic.
