Photon mass attenuation coefficients of a silicon resin loaded with WO3, PbO, and Bi2O3 Micro and Nano-particles for radiation shielding

Investigation of fast neutron shielding properties of new polyurethane-based composites loaded with B4C, BeO, WO3, ZnO, and Gd2O3 micro-and nanoparticles

“…Also, more homogenous composites can be made from nanoparticles compared to micro-fillers. This phenomenon is identical for both photons and neutrons and it has been reported in the previous studies [9][10][11]14,[16][17][18][19][20][21]. However, it should be reminded here that most of the studies have been conducted on photon beams and a few reports have examined the neutron beam attenuation by nanoparticles.…”

“…The majority of the investigations indicated that the nanoparticles improved attenuation coefficients of composites. Also, it was shown that photon and neutron energy, nanoparticle concentration and size of nanoparticles were effective parameters in the efficiency of nanoparticle-based shielding materials [9][10][11]. Several studies were investigated the effect of nano-materials on shielding properties of glasses [12,13].…”

“…There is a wide range of materials that were investigated as nano-and microparticles fillers in the fabrication of new shielding materials for photon and neutron beams [11]. In the current study, several nano-and microparticles including B 4 C, BeO, WO 3 , ZnO, and Gd 2 O 3 as potential candidates to make more efficient neutron attenuators were investigated by Monte Carlo method.…”

Synthesis and radiation shielding properties of polyimide/Bi2O3 composites

“…synthesized radiation-protective composites based on silicone resin and Bi 2 O 3 micro and nano-particles. The radiation-protective composites were made of nanoparticles having higher mass attenuation coefficients of γ-radiation relative to those made of microparticles [28]. Kurudirek et al.…”

High-Efficiency, Flexibility and Lead-Free X-ray Shielding Multilayered Polymer Composites

“…[8][9][10] Noor Azman et al used bismuth or bismuth oxide, tungsten, tungsten carbide, tungsten oxide, bismuth tungstate, nanogold, nanosilver, and graphene as replacements for lead and lead-based compounds and fabricated polymer composites for shielding X-rays. [11][12][13] Importantly, the absorption blindness of these lead-based shielding materials in 70-90 keV range was offset in the case of the polymer composites by the compounding effect of the functional llers, which were of different types and whose particles were of different sizes.…”
