Absorption characteristics of composite ordinary portland cement (OPC)/Fe2 O3 /BaO X-ray shield applications

Composite materials for X-ray shield aplications have been synthesized used the
ordinary portland cement (OPC) as matrix material and Fe2O3 and BaO as fillers material.
There are four compositions of the (Fe2O3 + BaO); namely OFB 1 for 0%, OFB 2 for 5% ,
OFB 3 for 10%, and OFB 4 for 15%. The chemical composition of the composites were
determined by X-ray fluorescence (XRF) spectroscopy and for structural properties
determined by X-ray diffraction (XRD). For the absorption characteristics were determined
by using mobile X-Ray and analysis the linear coefficient attenuation (μ), the half value layer
(HVL), the tenth value layer (TVL), and the absorbed dose (S) for various of the tube
voltage; 60 kV, 70 kV and 80 kV. The absorption dose was increase with increasing the
amount of (Fe2O3 + BaO) as fillers at the same tube voltage, but decreasing the absorption
dose for the tube voltage of radiation source increased. The best absorption dose is for
composite OFB 4 on the source tube voltage of 60 kV with the value of μ, HVL, TVL and S
are 0.32 mm-1 , 2.13 mm, 7.09 mm, and 99.85%, respectively.
