摘要：

The ESR dose values of two human tooth enamel fragments were measured in 10 degrees steps with an automated goniometer. ESR spectra were deconvoluted using four Gaussian peaks. The central region of the spectra is interfered with by at least one additional line which yields significantly lower dose values than the central, apparently axial region. There is a clear relationship between dose and width of the deconvoluted axial peaks which is attributable to incomplete separation between the axial and interfering peaks. A simple model is presented that coherently explains all observations. We conclude that deconvolution is necessary for the estimation of the most likely dose value of enamel pieces.
