This procedure assures a never-ending following of the quality, accuracy and precision of the results given to customers.
CEN radiochronology laboratory also offers Pb-210 dating.
As Controls, three samples whose ages had been determined independently were also dated.
The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.
We are using the AMS method (Accelerator Mass Spectrometry). C-H-N analyses are also available now (possibility to get the percentages of C (Carbon), H (Hydrogen) and N (Nitrogen) for dry samples.It is possible to count the following radionuclides: Pb-210, Cs-137, Am-241, Cd-109, Co- 57 as well as Ra-226 (which is the average of Pb-214 and Bi-214) in sediments using the HPGe method (High-Purity Germanium detector). These steps (drying of the sample, crushing and homogenization) can be done by the customer, or by our people at the laboratory, which will make for a slightly higher price per sample.The Shroud of Turin (Turin Shroud), a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relic's authenticity. Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.After many journeys the shroud was finally brought to Turin in 1578 where, in 1694, it was placed in the royal chapel of Turin Cathedral in a specially designed shrine.Photography of the shroud by Secondo Pia in 1898 indicated that the image resembled a photographic 'negative' and represents the first modern study.
