Carbon dating shroud of
Chemical analysis, all nicely peer-reviewed in scientific journals and subsequently confirmed by numerous chemists, shows that samples tested are chemically unlike the whole cloth.
It was probably a mixture of older threads and newer threads woven into the cloth as part of a medieval repair.
"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.
Christopher Ramsey, the director of the Oxford Radiocarbon Laboratory, thinks more testing is needed. This is because there are significant scientific and non-religious reasons to doubt the validity of the tests.
One of the new articles quoted Pope John Paul II in 1998 saying continued research should be done.
I think researchers have done their part in continuing research but one can only do so much with the 1978 data.
It would have been nice if some of that time, energy and money could have been put in another multi-disciplinary study.
We now have Barberis saying another C-14 test should be done. Louis conference, there is a lot of debate among researchers whether it should be done.
