Abstract: In this work the ESR method has been applied to determine the age of fossil tooth enamel found in Mingachevir archeological site (Azerbaijan, Mingachevir). The EPR spectrum of tooth enamel has been deconvoluted into four individual Gaussian lines. Equivalent dose (Absorbed dose in tooth enamel that was historically accumulated due to natural irradiation) calculated using dose-response curves of individual Gaussian lines shows significantly different values. Peak 1 (with g= 2.006848) gives a significantly lower, Peak 4 (with g=2.002942) a significantly higher value of absorbed dose. The use of integrated spectra gives lower absorption dose values than the use of differential spectra.
