Fig. 5.2X-ray transmission as a function of filler loading of a 5 and 10 wt% and b 20–35 wt% of the nano-sized WO3-epoxy composite as compared to the micro-sized WO3-epoxy composite for X-ray tube voltage of 40–120 kV generated by general radiography unit [14]

Besides that, Fig. 5.3 showed that the value of Tn by the nano-sized WO3 epoxy composite is higher for the X-ray photon generated by 40 kV of the mammography unit compared to the same X-ray tube voltage (40 kV) selected from general radiography unit. A similar result was also obtained for micro-sized WO3 epoxy composite (Tm). This outcome proved that the general radiography unit comprised of a continuous spectrum of X-rays energy, which is having lower equivalent energies as compared to the characteristic X-ray energies produced from the mammography unit (17.5–22.7 keV).
