Effect of particle size, filler loadings and x-ray tube voltage on the transmitted x-ray transmission in tungsten oxide—epoxy composites
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 lo...

| Summary: | 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 (25–35 kV) 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 (40–120 kV). |
