The Zurich radiocarbon datings involved the use of AMS (“Accelerator Mass Spectrometry”), a method of radiocarbon dating which required only small sample sizes.
Before the advent of AMS the amount of material that was necessary to obtain an adequate amount of carbon made radiocarbon dating of texts impracticable.
The eight texts from Qumran dated generally in agreement with the existing more precise palaeographic date estimates on each of these texts, within margins of error (with the exception of one text, 4QTestament of Qahat, which gave a date inaccurately too early due to contamination).
It was an overstatement at the time for some to characterize these datings as having confirmed the exact accuracy of the palaeographic dating system, given the margins of error of the individual radiocarbon datings and so few texts dated.
Robert Eisenman and Philip Davies had written the director of the Israel Antiquities Authority, Amir Drori, urging the new method, AMS radiocarbon dating, be used to date the Dead Sea Scrolls.
