Abstract

This paper aim 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 OSLD in the Philippines. 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 OSL applications requiring higher doses of radiation (> 200cGy).
