“…Using of polymer composites in attenuation of gamma rays has become an interesting field of research and it plays an important role in gamma radiation protection; in particular protection from scattering radiation from materials along the path of photon source. In order to study the behavior and the performance of polymer composites in radiation protection application, it is important to identify the total attenuation cross-section which are the basic parameters for the determination of the penetration depth of the photon in any material [ 13 , 14 , 15 , 16 ].…”

Recently, polymers have entered into many medical and industrial applications. This work aimed to intensively study polypropylene samples (PP) embedded with micro and nanoparticles of PbO for their application in radiation shielding. Samples were prepared by adding 10%, 30%, and 50% by weight of PbO microparticles (mPbO) and adding 10% and 50% PbO nanoparticles (nPbO), in addition to the control sample (pure polypropylene). The morphology of the prepared samples was tested; on the other hand, the shielding efficiency of gamma rays was tested for different sources with different energies. The experimental linear attenuation coefficient (LAC) was determined using a NaI scintillation detector, the experimental results were compared with NIST-XCOM results, and a good agreement was noticed. The LAC was 0.8005 cm−1 for PP-10%nPbO and 0.6283 cm−1 for PP-10%mPbO while was 5.8793 cm−1 for PP-50%nPbO and 3.9268 cm−1 for PP-50%mPbO at 0.060 MeV. The LAC values have been converted to some specific values, such as half value layer (HVL), mean free path (MFP), tenth value layer (TVL), and radiation protection efficiency (RPE) which are useful for discussing the shielding capabilities for gamma-rays. The results of shielding parameters reveal that the PP embedded with nPbO gives better attenuation than its counterpart pp embedded with mPbO at all studied energies.

“…Polypropylenes are a low-cost material with exceptional mechanical, thermal, chemical, and physical features that are uncommon in other thermoplastic polymers [33,34]. They are distinguished by their lightweight, high tensile strength, high-pressure resistance, excellent insulating properties, resistance to most acids and alkalis, stress cracking resistance, low moisture absorption, non-toxicity, and ease of fabrication [35,36].…”

This article explores the processing of structural and thermal for polypropylene (PP) modified with Ni0.9Zn0.1Fe2O4 nanoparticles. The PP/Ni0.9Zn0.1Fe2O4 nanocomposites are manufactured by melt processing method. The structural investigations ensure the good incorporation of Ni0.9Zn0.1Fe2O4 on the PP matrix. It is noticed that adding Ni0.9Zn0.1Fe2O4 nanoparticles to the PP polymer matrix enhances the polymer's thermal stability. Additionally, the impacts of the addition of the Ni0.9Zn0.1Fe2O4 nanoparticles on the radiation shielding properties of fabricated PP-based composites were examined using the Monte Carlo simulation. The examination shows an enhancement in the fabricated composites’ linear attenuation coefficient with increased Ni0.9Zn0.1Fe2O4 nanoparticle concentrations. The linear attenuation coefficient increased by 13.12, 3.95, 2.35, 1.55, and 1.16 times at γ-ray energy of 0.033, 0.059, 0.081, 0.122, and 0.662 MeV. Furthermore, the increase in linear attenuation coefficient increases the radiation shielding efficiency for the fabricated composites, reaching 21.84%, 27.27%, 29.03%, and 31.77%, respectively, for 0.0 wt.%, 5.0 wt.%, 10 wt.%, and 15 wt.%, at 0.122 MeV. The study shows that the fabricated composites have suitable γ-ray shielding properties in lower energy than in the intermediate energy interval.

This work aimed to intensively study polypropylene samples (PP) embedded with micro- and nanoparticles of Bi2O3 for their application in radiation shielding. Samples were prepared by adding 10%, 20%, 30%, 40%, and 50% of Bi2O3 microparticles (mBi2O3) by weight, and adding 10% and 50% of Bi2O3 nanoparticles (nBi2O3), in addition to the control sample (pure polypropylene). The morphology of the prepared samples was tested, and also, the shielding efficiency of gamma rays was tested for different sources with different energies. The experimental LAC were determined using a NaI scintillation detector, the experimental results were compared with NIST-XCOM results, and a good agreement was noticed. The LAC values have been used to calculate some specific parameters, such as half value layer (HVL), mean free path (MFP), tenth value layer (TVL), and radiation protection efficiency (RPE), which are useful for discussing the shielding capabilities of gamma rays. The results of the shielding parameters show that the PP embedded with nBi2O3 gives better attenuation than its counterpart, PP embedded with mBi2O3, at all studied energies.
