Carbon dating shroud
These results therefore provide conclusive evidence that the linen of the Shroud of Turin is mediaeval. The radiocarbon measurements were done, not at one laboratory, but at three highly regarded institutions. The results provide not just evidence but conclusive evidence. Finally Ray Rogers, who had accepted the carbon dating, decided to disprove a crazy explanation from what he called the lunatic fringe.
After the results had been leaked, twenty-one scientists from the University of Oxford, the University of Arizona, the Institut für Mittelenergiephysik in Zurich, Columbia University, and the British Museum wrote in a peer-reviewed paper published in Nature in 1989: The results of radiocarbon measurements at Arizona, Oxford and Zurich yield a calibrated calendar age range with at least 95% confidence for the linen of the Shroud of Turin of AD 1260 - 1390 (rounded down/up to nearest 10 yr).
According to radiocarbon dating done in 1988, the cloth was only 728 years old at the time.
Other researchers have since suggested that the shroud is much older and that the dating process was incorrect because of neutron radiation – a process which is the result of nuclear fusion or nuclear fission during which free neutrons are released from atoms – and its interaction with the nuclei of other atoms to form new carbon isotopes.
The author concludes that, although the procedures followed differed substantially from those recommended at a workshop organized by the Pontifical Academy of Sciences, the results are credible.
It is suggested that steps should be taken to conserve the shroud and that permission should be given for its examination by experts in medieval art.
However, no plausible physical reason has yet been proposed to explain the origin of this neutron radiation.
Now Carpinteri's team, through mechanical and chemical experimentation, hypothesizes that high-frequency pressure waves generated in the Earth's crust during earthquakes are the source of such neutron emissions.
Does this not suffice to answer the students’ questions? The crazy idea was that the Shroud had been mended and the samples were from that mending job.
What Rogers discovered was that the crazy idea seemed to be right.
