An anonymous reader writes: The Telegraph reports, "The Turin Shroud may not be a medieval forgery after all, after scientists discovered it could date from the time of Christ. ... a new study claims that an earthquake in Jerusalem in 33AD may have not only created the image but may also have skewed the dating results. The Italian team believes the powerful magnitude 8.2 earthquake would have been strong enough to release neutron particles from crushed rock. This flood of neutrons may have imprinted an X-ray-like image onto the linen burial cloth, say the researchers. In addition, the radiation emissions would have increased the level of carbon-14 isotopes in the Shroud, which would make it appear younger. ... Carpinteri's team have hypothesized that high-frequency pressure waves generated in the Earth's crust during earthquakes are the source of such neutron emissions. The scientists base the idea on research into piezonuclear fission reactions which occur when brittle rock is crushed under enormous pressure."
