In this work, Al2O3 doped with Sr, Li and Ge was prepared by combustion synthesis techniques for thermoluminescent (TL) ionizing radiation dosimetry applications. Dopants sample concentration were varied from 0.1 mol% to 5 mol% in order to study the effect of the concentration on the TL response. The optimum concentration was found to be 0.3 mol% for Sr and Li and 3.0 mol% for Ge. Based from the comparison of this doped material, the highest sensitivity was found for Ge doped and linear response for doses studied range of 10-80 Gy. X-Ray diffraction (XRD) patterns of the samples were recorded to confirm the formation of the sample. The sharp peaks present in the XRD confirms the sample is crystalline. The TL response of these samples for Co -60 gamma radiation were evaluated. It was observed a TL glow peak around 175̊C for doped sample which is suitable for radiation dosimetry.
