Radioactive dating used for dating the turin shroud

The author dismisses 1988 carbon-14 dating tests which concluded that the linen sheet was a medieval fake.

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.

It was this material that was responsible for an invalid date being assigned to the original shroud cloth, he argues.

New scientific tests on the Shroud of Turin, which went on display Saturday in a special TV appearance introduced by the Pope, dates the cloth to ancient times, challenging earlier experiments dating it only to the Middle Ages.

Pope Francis sent a special video message to the televised event in the Cathedral of Saint John the Baptist in Turin, Italy, which coincided with Holy Saturday, when Catholics mark the period between Christ's crucifixion on Good Friday and his resurrection on Easter Sunday.

This flood of neutrons may have imprinted an X-ray-like image onto the linen burial cloth, say the researches.

In addition, the radiation emissions would have increased the level of carbon-14 isotopes in the Shroud, which would make it appear younger.

The third was a multi-parametric mechanical test based on five different mechanical parameters linked to the voltage of the wire.

But Cesare Nosiglia, the Archbishop of Turin and "pontifical custodian of the shroud," said the special display on Holy Saturday "means that it represents a very important testimony to the Passion and the resurrection of the Lord," The Telegraph reported.

The burial shroud purports to show the imprint of the face and body of a bearded man.

The machine used to examine the Shroud's fibres and test traction, allowed researchers to examine tiny fibres alongside about twenty samples of cloth dated between 3000 BC and 2000 AD.

"Final results show that the Shroud fibres examined produced the following dates, all of which are 95% certain and centuries away from the medieval dating obtained with Carbon-14 testing in 1988: the dates given to the Shroud after FT-IR testing, is 300 BC 400, 200 BC 500 after Raman testing and 400 AD 400 after multi-parametric mechanical testing.
