TL glow peaks at 78 degrees C and 225 degrees C are observed. The intensity of the glow peak at 225 degrees C increased with a faster heating rate. To gain insight into the trap activation energies, the methods of Hoogenstraaten and Booth-Bohun-Parfianovitch were used, where the calculated activation energies are 0.57 eV and 0.60 eV for Peak I and 1.69 eV and 1.71 eV for Peak II respectively. The dose-response of GAB:0.5 wt%Sm3+ demonstrates robust linearity up to 40 Gy, with a strong correlation coefficient of 0.999. Both TM-Tstop combined with the Initial Rise (IR) and Computerized Glow Curve Deconvolution (CGCD) techniques were employed, which revealed six overlapping glow peaks beneath the main peaks. Additionally, the results suggest that the TL signal can be efficiently exploited for radiation dosimetry applications.eninfo:eu-repo/semantics/closedAccessThermoluminescence; Unusual Heating Rate; LinearityArticle10.1016/j.radphyschem.2023.111211213N/AWOS:0010657435000012-s2.0-85168415018Q2
