Carbon dating and shroud of turin
(Phys.org) —An earthquake in Old Jerusalem might be behind the famous image of the Shroud of Turin, says a group of researchers led by Alberto Carpinteri of the Politecnico di Torino in Italy in an article published in Springer's journal Meccanica.
They believe that neutron radiation caused by an earthquake could have induced the image of a crucified man – which many people believe to be that of Jesus – onto the length of linen cloth, and caused carbon-14 dating done on it in 1988 to be wrong.

Garbling would be more difficult to explain if the numbers had been, say, 200 A. It's common for the reporting of an actual event to become garbled over time.
We have the blog set up that way in order to avoid having posts appear in old threads without our knowing of it. Often, a historical core of information will be surrounded by a lot of misinformation and contradictions (e.g., early reports of the death of Osama bin Laden).
Attempts to clarify these matters ought to be made sooner rather than later.
I can name some of the sources for my information below, but there are other sources I can't name for various reasons. In this case, there are some factors involved that help explain how poorly the story has been preserved.
"We believe it is possible that neutron emissions by earthquakes could have induced the image formation on the Shroud's linen fibres, through thermal neutron capture on nitrogen nuclei, and could also have caused a wrong radiocarbon dating," hypothesizes Carpinteri.

The researchers therefore believe that neutron emission from a historical earthquake in 33 A. in Old Jerusalem, which measured 8.2 on the Richter Scale, could have been strong enough to cause neutron imaging through its interaction with nitrogen nuclei.
On the one hand, this could have created the distinctive image on the Shroud through radiation imagery, while on the other, it could have increased the level of carbon-14 isotopes found on the linen fibres that could have confused the 1988 radiocarbon dating tests.The Shroud has attracted widespread interest ever since Secondo Pia took the first photograph of it in 1898: about whether it is Jesus' purported burial cloth, how old it might be, and how the image was created.According to radiocarbon dating done in 1988, the cloth was only 728 years old at the time.I don't claim to have even come close to resolving all of the difficulties.
