“…In particular, when mixing with a polymer series, the clustering effect can be predicted to be high, as the particle size is small. Future studies should compare the effects with other materials, such as rubber [39]. Furthermore, prior studies showed that the mixing of particle size and the base material that disperses it is crucial in the shielding-sheet manufacturing process, and that small particles generally exhibit high dispersion forces [40].…”

In the field of medical radiation shielding, there is an extensive body of research on process technologies for ecofriendly shielding materials that could replace lead. In particular, the particle size and arrangement of the shielding material when blended with a polymer material affect shielding performance. In this study, we observed how the particle size of the shielding material affects shielding performance. Performance and particle structure were observed for every shielding sheet, which were fabricated by mixing microparticles and nanoparticles with a polymer material using the same process. We observed that the smaller the particle size was, the higher both the clustering and shielding effects in the high-energy region. Thus, shielding performance can be improved. In the low-dose region, the effect of particle size on shielding performance was insignificant. Moreover, the shielding sheet in which nanoparticles and microsized particles were mixed showed similar performance to that of the shielding sheet containing only microsized particles. Findings indicate that, when fabricating a shielding sheet using a polymer material, the smaller the particles in the high-energy region are, the better the shielding performance is. However, in the low-energy region, the effect of the particles is insignificant.

“…In living cells, possible effects of ionizing radiation such as gamma rays and X-rays require strong radiation protection. High-density materials such as lead and concrete for protection from radiation must be high-density materials, which can act as barriers and reduce the effect of radiation 7 . Still, most scientists now think of new materials with environmentally friendly concepts.…”

Composite cement/BaSO4/Fe3O4/CuO with a thickness of 0.6 cm for various amounts of CuO: 2 wt%, 4 wt%, 6 wt%, and 8 wt% were successfully synthesized for the X-ray radiation shield. The bonding characteristics of composite and structural properties were determined using Fourier transform infrared spectra for the wavelength range of 4000–400 cm−1 and X-ray diffraction with the range of 2θ from 25° to 50°, respectively. The shielding ability was measured using a mobile X-ray with an energy of 55, 66, and 77 keV for determining the mass and linear attenuation coefficient, electronic and atomic cross-section. These shield characteristics best agreement with theoretical calculation from the XCOM database for energy < 77 keV with half value layer (HVL) < 0.3 cm. The best shielding in this study indicated by the lowest HVL and MFP is composite for CuO 8 wt%. The HVL and MFP shows better values compared to the previous reported using composite rubber-based, indicated high potentials composite in this study for design new and efficient radiology rooms as an alternative concrete, especially for X-ray radiation, in the future.

Reinforcement of the flexible shielding properties of natural rubber (NRL) was achieved through various content Multi-walled carbon nanotubes (MWCNTs) prepared from a simple solution using mixing method. We reported the structure change of NRL upon addaing different contenets of MWCNTs. The results from the X-ray diffraction, Scanning electron microscopy and Fourier-transform infrared spectroscopy revealed that the nanocomposites have been successfully prepared, making them fitting to impact significant improvement on the mechanical strength of the matrix. The frequency dependence of the dielectric constant, dielectric loss and AC conductivity of the NRL/MWCNTs nanocomposites at room temperature under different nanotube loading conditions were invistgated. The radiation shielding characteristics such as the linear attenuation coefficients (l) and half-value thickness for NRL/MWCNTs nanocomposite films were presented.Thus, from the obtained results, it can be concluded that nanocomposite films offer promising radiation-shielding properties.
