Carbon dating laboratories
The radiocarbon lab at Geochron uses gas proportional counters to measure methane derived from relatively small samples.
We also offer liquid scintillation analysis using an extra low background Quantulus 1220 for high precision measurements on benzene.
U of I researchers should specify U of I funds (i.e., CFOP) to be used for payment during sample submission.
External submitters should receive a UIUC Banner account prior to sample submission. Payment can be made online by going to and logging in with the UIUC Banner account number assigned to your department, group, or business.
The idea of scientifically dating the shroud had first been proposed in the 1960s, but permission had been refused because the procedure at the time would have required the destruction of too much fabric (almost 0.05 sq m ≅ 0.538 sq ft). P.), which involved about 30 scientists of various religious faiths, including non-Christians. Testore performed the weighting operations while Riggi made the actual cut.
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.
The method takes advantage of the natural occurrence of a radioactive isotope of carbon (C in samples of ancient carbon compounds and comparing this with the amount in modern materials, it is possible to determine the time of cessation of carbon exchange with the atmosphere. that radiocarbon measurements on the shroud should be performed blind seem to the author to be lacking in merit; … group and the candidate laboratories turned into a P. However, in a 1990 paper Gove conceded that the "arguments often raised, … 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. 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.
Samples and Services The Radiocarbon Dating Laboratory accepts a variety of samples including: Before mailing any samples, please contact the lab at [email protected] discuss the number and types of samples.
