Carbon dating has a certain margin of error, usually depending on the age and material of the sample used.Carbon-14 has a half-life of about 5730 years, so researchers use the process to date biological samples up to about 60,000 years in the past.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.In 1988, scientists at three separate laboratories dated samples from the Shroud to a range of 1260–1390 AD, which coincides with the first certain appearance of the shroud in the 1350s and is much later than the burial of Jesus in 30 or 33 AD. Samples were taken on April 21, 1988, in the Cathedral by Franco Testore, an expert on weaves and fabrics, and by Giovanni Riggi, a representative of the maker of bio-equipment "Numana".The level of atmospheric Radiometric dating in general, of course, poses a huge problem for people who believe that the universe is 6000-odd years old.
group expected to perform the radiometric examination under its own aegis and after the other examinations had been completed, while the laboratories considered radio-carbon dating to be the prime test, which should be completed at the detriment of other tests, if necessary.
that discarding the blind-test method would expose the results – whatever they may be – to suspicion of unreliability.
Shredding the samples would not solve the problem, while making it much more difficult and wasteful to clean the samples properly.
Carbon-dating Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.
These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.
