摘要：

A brief overview of some of the potential sources of inaccuracies that are common to all kinds of electron paramagnetic resonance (EPR) dosimetry is given. The instrumental sources discussed are inaccuracies of receiver gain calibration, instability of the spectrometer sensitivity, and neglect of inhomogeneity of the fields in the resonators. The discussed sources of inaccuracies related to data processing are violations of basic assumptions of the used version of the least-squares technique, incorrect model selection for fitting the data, and nonoptimal design of the calibration experiment. Methods for detecting and correcting such inaccuracies are briefly discussed and references to the original literature are given. (C) 2000 Elsevier Science Ltd, All rights reserved.
