- Abstract
X-ray aprons are important for protecting radiation workers and patients from radiation. The ideal apron is flexible, lightweight, environmentally friendly, thin, and possesses a high absorption efficiency. In this study, the composite Fe2O3/BaCO3 was synthesized via mixing for 4 and 8 h followed by calcination at different temperatures: 700 °C, 800 °C, 900 °C, and 1000 °C. The flexible composite apron Fe2O3/BaCO3/polyvinyl alcohol (PVA) was prepared using Fe2O3/BaCO3 as a filler and polyvinyl alcohol (PVA) as a binder. The structural properties, bonding characteristics, particle shape, and absorption performance were analyzed via X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy, and a mobile X-ray test, respectively, for irradiation energies of 55, 60, 70, and 77 keV. The linear attenuation coefficient μ, mass attenuation coefficient μm, electronic cross section σel, and atomic cross section σa were determined to elucidate the physical phenomena when the photons travel inside the composite, and the experimental results were compared with the theoretical calculation from the XCOM database. The aprons prepared at a calcination temperature of 700 °C and mixing times of 4 and 8 h exhibited the lowest half-value layer and mean free path owing to electron migration, magnetic domain wall loss, and electron spin loss during collisions between the particles in the composite. The experimental results agreed well with the theoretical calculation from the XCOM database in terms of µ, µm, σa, and σel. The results of this study demonstrate the potential of the composite as a new alternative material for preparing environmentally friendly flexible thin X-ray aprons.
