In recent years, polymer-based hybrid nanocomposites have emerged as promising
alternatives to traditional heavy metal shields due to their low density, flexibility, and
environmental safety. In this study, the synthesis of PS-PEG copolymers and the gamma
radiation-shielding properties of PS-PEG/As₂O₃, PS-PEG/BN, and PS-PEG/As₂O₃/BN
Nanocomposites with different compositions are investigated. The goal is to find the
optimal nanocomposite composition for gamma radiation shielding and dosimetry.
Therefore, the mass attenuation coefficient (MAC), linear attenuation coefficient (LAC),
half-value layer (HVL), tenth-value layer (TVL), effective atomic number, mean free path
(MFP), radiation shielding efficiency (RPE), electron density, and specific gamma-ray
constant were presented. Gamma rays emitted by the Eu source were detected by a high-purity
germanium (HPGe) detector device. GammaVision was used to analyze the given
data. Photon energy was in the vicinity of 121.8–1408.0 keV. The MAC values in XCOM
Simulation tools were used to compute. Gamma-shielding efficiency was increased by an
increased number of NPs at a smaller photon energy. At 121.8 keV, the HVL of a
composite with 70 wt% As₂O₃ NPs is 2.00 cm, which is comparable to the HVL of lead
(0.56 cm) at the same energy level. Due to the increasing need for lightweight, flexible,
and lead-free shielding materials, PS-b-PEG copolymer-based nanocomposites reinforced
with arsenic oxide and BN NPs will be materials of significant interest for next-generation
radiation protection applications.
