Purpose: Nanotechnology has become a fascinating issue for radiation protection researchers. Finding an alternative for the common protective garment was necessary due to its problems associated with it. Many studies have shown that nanoparticles can be an appropriate candidate for x-ray shielding in diagnostic radiology. However, single-walled carbon nanotubes (SWCNTs) in nanocomposites made it lighter and more strength. The purpose of this study was to investigate the effect of single-wall carbon nanotubes on protective garment efficiency against diagnostic x-rays.
Methods: (PDMS) nanocomposites were fabricated by mixing solution procedure with Cerium Oxide nanoparticles (nanoceria) and SWCNT as filler. Specimens were characterized by the Field Emission Scanning Electron Microscope (FE-SEM) and the Fourier Transform Infrared Radiation (FTIR) test. The nanocomposites were exposed by a diagnostic X-ray apparatus at energies 60, 80, 100, and 120 kVp. X-ray attenuation characteristics were measured with Piranha red dosimeter at narrow beam geometry.
Results: The FE-SEM images exhibiting the uniform dispersion, and FTIR dates confirmed nanocomposite characteristics. The attenuation of nanocomposites reinforced with SWCNTs was 5 to 12 percent higher than that were reinforced without it. Interestingly, its mass thickness was less than 12% of nanocomposite reinforced without SWCNTs (p< 0.05).
Conclusion: The results of this study indicated that SWCNT can improve the efficiency of radiation protective garment both in terms of weight and attenuation capability.
