Abstract

The effect of particle size, filler loadings and x-ray tube voltage on the x-ray transmission in WO3-epoxy composites has been investigated using the mammography unit and a general radiography unit. Results indicate that nano-sized WO3 has a better ability to attenuate the x-ray beam generated by lower tube voltages (25-35kV) when compared to micro-sized WO3 of the same filler loading. However, the effect of particle size on x-ray transmission was negligible at the higher x-ray tube voltages (40-120kV).
