Abstract

This work aims to extract Al2O3 from Ultisols through calcination, acid leaching, filtering, and precipitation, and evaluate its dose linearity response from 50cGy–1000cGy to develop a more accessible and cost-effective optically stimulated luminescence dosimeter (OSLD). The derived material was characterized using XRD and XRF analysis, which revealed that the material has 63.28% purity of α-Al2O3. The dose linearity of derived Al2O3-based material was evaluated and compared to standard Al2O3:C using Monte Carlo simulation in PHITS. It was found that the derived Al2O3 has a better dose absorption on higher doses than standard Al2O3:C capable of being used for several OSLD applications requiring higher doses of radiation (> 200 cGy).
