Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly. 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 it was therefore still possible for a laboratory to identify the shroud sample.In a well-attended press conference on October 13, Cardinal Ballestrero announced the official results, i.e.that radio-carbon testing dated the shroud to a date of 1260-1390 CE, with 95% confidence. Carbon-14 dating can be used on objects ranging from a few hundred years old to 50,000 years old.
that discarding the blind-test method would expose the results – whatever they may be – to suspicion of unreliability.The official and complete report on the experiment was published in Nature.As reported in Nature, Professor Bray of the Instituto di Metrologia 'G.Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years. Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.The Shroud of Turin, 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. 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.
