Composites Based Ordinary Portland Cement and Fe₂O₃ for X-Ray Shield Applications

Abstract

The shielding material of X-Ray has been synthesized from Ordinary Portland Cement (OPC) as a matrix and Fe2O3 (FE) as a filler by four different composition are A1, A2, A3 and A4 for 0 wt%, 5 wt%, 10 wt% and 15 wt% of Fe2O3, respectively. The matrix and filler materials are characterized using X-Ray Fluorescence (XRF). For OPC-FE composites were characterized using X-Ray Diffraction (XRD) and Mobile X ray with tube voltages are 63 kV & 73 kV and 85 kV for each samples to analyze the absorption characteristics. The results obtained showed that the dose reduction of X-Ray radiation increases with increasing wt% of FE, but decreased with increasing tube voltage. The best results were obtained on A4 samples when the tube voltage is 63 kV, the value of μ is 0.22 mm-1, HVL is 3.12 mm, and the absorption from the X-Ray radiation source is 98.82%.
