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.
The shroud, which bears the faint image of a blood-covered man, is believed by some to be Christ's burial cloth.
Raymond Rogers says his research and chemical tests show the material used in the 1988 radiocarbon analysis was cut from a medieval patch woven into the shroud to repair fire damage.
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 idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.
Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.
It was, as far as logic went, like making a printing press and printing a Bible to show that Leonardo might have invented printing.This is based on their research into piezonuclear fission reactions, which are triggered when very brittle rock specimens are crushed under a press machine.In the process, neutrons are produced without gamma emissions.Nathan Wilson, an English teacher at a small mid-western college, very much convinced that the shroud was fake because it contradicted his literal reading of the Gospel of John, created an interesting shroud-like image by sun-bleaching unbleached linen with a mask painted on a piece of glass.But it, too, failed to reproduce many of the shroud’s features, in fact most of them.
The 4m-long linen sheet was damaged in several fires since its existence was first recorded in France in 1357, including a church blaze in 1532.
