Investigation of the radiation absorption parameters of dental Yttria-stabilized zirconium dioxide

Abstract Yttria stabilized zirconia (YSZ) is becoming increasingly popular in the field of dental biomaterial due to its faster production process, reduced preparation thickness, and lower cost. This study aims to compare the experimentally obtained gamma-ray absorption coefficients for YSZ dental biomaterial with theoretical data generated through GAMOS simulation and Phy-X/PSD software. The minimal µ value is determined to be 0.274 cm –1 at an energy of 1408 keV. The µ/ρ values for the 662 keV gamma ray, derived from experimental data, GAMOS simulation, and the Phy-X/PSD algorithm, are 0.070, 0.072, and 0.074 cm²/g, respectively. As gamma energy escalates, both the half-value layer and the tenth-value layer also increase. Comparable results are obtained from both the experimental data and the datasets generated by Phy-X/PSD and GAMOS. The mean free path value is measured to be 3.645 cm using 1408 keV photons. The experimentally obtained data show good agreement with the results obtained from the GAMOS simulation and the Phy-X/PSD program.
