Carbon dating dead sea scrolls

As a second caveat, they insisted that opposition scholars be included in the process because they were the ones must likely to understand which were the key documents that should be tested and "they were the ones who felt the most need for it.The name Dead Sea Scrolls refers to some 1200 manuscripts found in caves in the hills on the western shore of the Dead Sea during the last 45 years.Libby had first started using the dating method in 1946 and the early testing required relatively large samples, so testing on scrolls themselves only became feasible when methods used in the dating process were improved upon. Davies made a request to date a number of scrolls, which led to a series of tests carried out in Zurich on samples from fourteen scrolls.Among these were samples from other sites around the Dead Sea, which contained date indications within the text to supply a control for the carbon dating results.To check this evidence, radiocarbon ages of 14 selected scrolls were determined using accelerator mass spectrometry.The calibrated radiocarbon ages agree well, except in one case, with the paleographic estimates or the specific dates noted on the scrolls.

The column headed "14C Age" provides a raw age before 1950 for each sample tested.One was that the new methods of dating materials should be applied to determine relative not absolute chronology, that is, earlier versus later in the same test run -- absolute chronology in their view being virtually impossible to determine because of the multiple imprecisions to which C14 testing was subject.To put this in another way, they framed their request in this manner because they did not believe that anything conclusive regarding the absolute dating of the Scrolls could be achieved with a technique as subject to multiple imprecisions as carbon testing was.Carbon dating the Dead Sea Scrolls refers to a series of radiocarbon dating tests performed on the Dead Sea Scrolls, first by the AMS (Accelerator Mass Spectrometry) lab of the Zurich Institute of Technology in 1991 and then by the AMS Facility at the University of Arizona in Tucson in 1994-95.There was also a historical test of a piece of linen performed in 1950 by Willard Libby, the inventor of the dating method.
