The present study aims to reveal thermoluminescence (TL) features of natural dolomite mineral. In the first stage, the
proper filter was selected as WBB with HR of 2 oCs-1 from RT to 450 °C. The results obtained from TL glow curves showed that
the curves were composed of two peak maxima (pm) located at 102 and 252 C at doses between 0.11-10 Gy. When examined the
dose dependence of each peak maxima, each of them exhibited a good linear response. The mineral was found to be reusable within
8% and 16% for peak 1 and 2, respectively. The effects of the HRs in the range of 0.5-10 Cs-1 on TL were researched taking into
account the change of the FWHM, Tm, Im and peak area vs HR for each pm and observed an anomalous case increasing TL intensity
with HR. The Tm-Tstop experiment and CGCD analyses performed showed that the curves consist of at least 8 superposition peaks.
The Ea values are in good agreement at both methods and found to be 0.65-1.08 (p1) and 1.4-1.71 eV (p2) applying CGCD method.
