Kinetic analysis of the main thermoluminescence glow peak in α-Al2O3

In this work the kinetic parameters of the main peak of the TL glow curve of alumina (α-Al2O3) irradiated at different doses are reported. Samples were irradiated at different X-ray doses using a 6 MeV linear accelerator (LINAC), in air at room temperature. The Initial rise, peak shape, whole glow peak and curve fitting methods were used for the kinetic analysis. The glow curves of the α-Al2O3 samples exhibited a total of three experimental glow peaks, the main peak located between 160 and 170 °C. The behavior of the kinetic parameters (activation energy E, frequency factor s and order parameter b) of the main peak of the TL glow curve, is independent of the radiation dose received by the material. •The kinetic parameters of the main peak of the TL glow curve of alumina (α-Al2O3) irradiated at different doses are reported.•The Initial rise, peak shape, whole glow peak and curve fitting methods were used for the kinetic analysis.•The glow curves of the α-Al2O3 samples exhibited a total of three glow peaks, the main peak located between 160 and 170 °C.•The behavior of the kinetic parameters (activation energy, frequency factor and order parameter) is independent of the radiation dose received.•The response of the material with dose is linear in the range used (≤10 Gy).
