The development in the 1970s of new techniques for radio-carbon dating, which required much lower quantities of source material, prompted the Catholic Church to found the Shroud of Turin Research Project (S. Also present were Cardinal Ballestrero, four priests, archdiocese spokesperson Luigi Gonella, photographers, a camera operator, Michael Tite of the British Museum, and the labs' representatives.
group initially planned to conduct a range of different studies on the cloth, including radio-carbon dating. The six labs that showed interest in performing the procedure fell into two categories, according to the method they utilised: In 1982, the S. The blind-test method was abandoned because the distinctive three-to-one herringbone twill weave of the shroud could not be matched in the controls, and a laboratory could thus identify the shroud sample.
The Radiocarbon Dating Laboratory of the IFAO, which main purpose is to satisfy the needs of the archaeological community in Egypt began operations in 2006. The main purpose of such a laboratory, integrated in an archaeological institute, is to study series of samples with solid archaeological context in order to solve questions of absolute chronology.
We welcome all projects of collaboration with other archaeological organizations as well as with other radiocarbon dedicated laboratories.
In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly.
To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age.
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5730 years.
lack of blindness in the measurements is a rather insubstantial reason for disbelieving the result." (t)he Church must respond to the challenge of those who want it to stop the process, who would want us to show that the Church fears the science.
that radiocarbon measurements on the shroud should be performed blind seem to the author to be lacking in merit; …
Gove consulted numerous laboratories which were able at the time (1982) to carbon-date small fabric samples. [...] The pressure on the ecclesiastic authorities to accept the Turin protocol have almost approached illegality.
group published the list of tests to be performed on the shroud; these aimed to identify how the image was impressed onto the cloth, to verify the relic's purported origin, and to identify better-suited conservation methods. We are faced with actual blackmail: unless we accept the conditions imposed by the laboratories, they will start a marketing campaign of accusations against the Church, which they will portray as scared of the truth and enemy of science.
