Shroud of turin carbon dating wrong

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.

In October 1987, the offers from three AMS laboratories (Arizona, Oxford and Zurich) were selected by the Archbishop of Turin, Pontifical Custodian of the shroud, acting on instructions from the Holy See, owner of the shroud. Samples weighing 50 mg from two of the three controls were similarly packaged.Testore of Department of Materials Science, Turin Polytechnic and G. If the samples had been unravelled or shredded rather than being given to the laboratories as whole pieces of cloth, then it would have been much more difficult, but not impossible, to distinguish the shroud sample from the controls.Vial of Musée des Tissues and Centre International d'Étude des Textiles Anciens in Lyon), Dr M. Tite of the British Museum, representatives of the three radiocarbon-dating laboratories (Professor P. (With unravelled or shredded samples, pretreatment cleaning would have been more difficult and wasteful.) Because the shroud had been exposed to a wide range of potential sources of contamination and because of the uniqueness of the samples available, it was decided to abandon blind-test procedures in the interests of effective sample pretreatment.But the three laboratories undertook not to compare results until after they had been transmitted to the British Museum.Also, at two laboratories (Oxford and Zurich), after combustion to gas, the samples were recoded so that the staff making the measurements did not know the identity of the samples. On the basis of the Islamic embroidered pattern and Christian ink inscription, this linen could be dated to the eleventh to twelfth centuries AD. Linen from the collection of the Department of Egyptian Antiquities at the British Museum, associated with an early second century AD mummy of Cleopatra from Thebes (EA6707).Even for the first investigation, there was a possibility of using radiocarbon dating to determine the age of the linen from which the shroud was woven.The size of the sample then required, however, was ~500cm, which would clearly have resulted in an unacceptable amount of damage, and it was not until the development in the 1970s of small gas-counters and accelerator-mass-spectrometry techniques (AMS), requiring samples of only a few square centimetres, that radiocarbon dating of the shroud became a real possibility. The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.At the same time, the British Museum was invited to help in the certification of the samples provided and in the statistical analysis of the results. The age of the shroud is obtained as AD 1260-1390, with at least 95% confidence. The three containers containing the shroud (to be referred to as sample 1) and two control samples (samples 2 and 3) were then handed to representatives of each of the three laboratories together with a sample of the third control (sample 4), which was in the form of threads.The procedures for taking the samples and treating the results were discussed by representatives of the three chosen laboratories at a meeting at the British Museum in January 1988 and their recommendations = standard deviation) errors, of the Shroud of Turin and control samples, as supplied by the three laboratories (A, Arizona; O, Oxford; Z, Zurich) (See also Table 2.) The shroud is sample 1, and the three controls are samples 2-4. The sampling of the shroud took place in the Sacristy at Turin Cathedral on the morning of 21 April 1988. All these operations, except for the wrapping of the samples in foil and their placing in containers, were fully documented by video film and photography."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.Explore further: Age test of Shroud of Turin planned More information: Carpinteri, A. Is the Shroud of Turin in relation to the Old Jerusalem historical earthquake?


  1. Chemistry Today vol 26 n4/Jul-Aug 2008, "Discrepancies in the radiocarbon dating area of the Turin shroud,". It may well go down as the biggest radiocarbon dating mistake in history; not because there is anything wrong with the measurement process there may not have been; not because there is anything inherently.

  2. Feb 11, 2014. An earthquake in Jerusalem in AD 33 may have caused an atomic reaction which created the Turin Shroud and skewed radiocarbon dating results. image formation on the Shroud's linen fibres, through thermal neutron capture on nitrogen nuclei, and could also have caused a wrong radiocarbon dating,".

  3. New Shroud of Turin scientific evidence and tests prove Shroud of Turin is original burial cloth of Jesus. 1988 Shroud carbon testing dates wrong because samples tested were from repaired corners of the Shroud.
