Interlaboratory comparison of tooth enamel dosimetry on Semipalatinsk region: Part 2, Effects of spectrum processing

In order to investigate the effects of spectrum processing procedures on the results of dose determination using EPR spectroscopy of human tooth enamel, spectra of the same samples measured in different laboratories in the course of the intercomparison were processed by some of the participants using their own unique procedures. Spectra of samples irradiated to known doses (calibration samples) and of samples irradiated to doses unknown to the participants (test samples) were analyzed. By comparison of the results obtained using different spectrum processing methods, it is shown that the precision of calibration and the accuracy of dose determination may be improved by appropriate choice of spectrum processing procedure.
