When something dies, it stops taking in carbon (ie stops eating or photosynthesizing or whatever) and the C14 slowly decays, making less C14 in an old dead thing than a live thing.The Dead Sea Scrolls refer to ancient Hebrew scrolls that were accidentally discovered in 1947 by a Bedouin boy in Israel's Judean Desert. E.) - a time of crucial developments in the crystallization of the monotheistic religions.

The pretreatment methods that produced the most accurate 14C dates and acceptable C: N ratios were found to be ABA protocols (without bleach) and collagen extraction; solvent washes and acid pretreatments alone were not sufficient to remove all contaminants and produce reliable 14C dates.ABSTRACT: A range of pretreatment methods was applied to 6 known-age historical parchments to investigate the most suitable methods for effectively removing contamination and ensuring accurate radiocarbon dates while minimizing unnecessary destruction of potentially valuable historical documents.The methods tested included an acid wash, different concentrations of acid-base-acid (ABA) pretreatments, the current routine ABA method applied at the Oxford Radiocarbon Accelerator Unit (ORAU) that includes an additional bleach treatment, and extraction of collagen.We report on new 14C measurements of samples of 18 texts (scrolls) and 2 linen fragments from Qumran Caves 1, 2, and 4 and from Na al ever, both in the Dead Sea region.The radiocarbon results are in good agreement with estimates of age based on paleography.ABSTRACT: An overview is provided of spectrometric methods useful for age estimation of historical manuscripts (medieval ones in particular), in order to confirm their authenticity.

Individual methods (infrared and Raman spectroscopy, mass spectrometry, atomic emission spectroscopy, X-ray spectroscopy, and electron scanning microscopy) are discussed and examples of their application described.The remaining four scrolls reached the hands of Mar Athanasius Yeshua Samuel, Metropolitan of the Syrian Jacobite Monastery of St. In 194-9 he traveled to the United States with the scrolls, but five years went by before the prelate found a purchaser. 3) A laboratory in Zurich employing a new, improved method of carbon-14 dating has pinpointed the age of the Dead Sea Scrolls to between the second century BCE and the beginning of the first century C. C14 only works on materials that were alive at one time, such as plant or animal matter.There is a constant amount of C14 in the world, is the assumption.One discovery led to another, and eleven scroll-yielding caves and a habitation site eventually were uncovered.
