Nickel ferrite nanoparticles were synthesised using a glycine-assisted auto-combustion method. The structural and magnetic characteristics of the resulting material were analysed using transmission electron microscopy, Fourier-transform infrared spectroscopy, X-ray diffraction, and vibrating sample magnetometry. Researchers evaluated the radiation shielding performance of the nanoparticles across photon energies between 0.015 and 15 MeV using MCNPX simulation code. Performance was compared to standard shielding media, including ordinary and mineral-based concretes, volcanic rock, and polymer composites. The synthesised nanoparticles provided complete, 100 percent X-ray protection alongside effective gamma-ray shielding up to 15 MeV. This approach offers a simple, affordable, and low-temperature fabrication route for functional nanomaterials relevant to radiation protection and display systems.
Protecting people and sensitive equipment from high-energy radiation typically requires bulky, heavy materials such as lead or dense concrete. Finding simpler, low-temperature ways to manufacture effective shielding at nanoscale could support safer environments in medical facilities, industrial plants, and advanced display electronics without relying solely on traditional, cumbersome shielding structures.
The findings point to potential uses in radiation shielding barriers and display device manufacturing. Likely industrial users include developers of radiation protection equipment and electronic displays. Given that the work couples laboratory-scale chemical synthesis with computational simulation, it sits at an early stage of development, requiring further engineering and physical prototype testing before commercial deployment.

This study aims to prepare NiFe 2 O 4 nanoparticles using a glycine assisted auto-combustion method. Characterization of the investigated ferrite was achieved by XRD, FTIR and TEM techniques. In addition, the magnetic properties of the as prepared ferrite using the VSM technique were determined. Furthermore, using MCNPX code, the X-ray/gamma ray shielding characteristics of NiFe 2 O 4 nanoparticles in the energy range of 0.015–15 MeV have been evaluated. In this study, a comparison was made between the shielding properties of the prepared sample and other typical gamma-ray shielding materials (Ordinary concretes, basalt magnetite, hematite serpentine, and Ilmenite limonite), and various shielding materials (P2 Polymer Guanine, T1, PCNK60, VR3 volcanic rock, SLGC-E5, LBZ4, RS-360, BBSN5.7, and TZE-F). The obtained results show that the current prepared sample provides full (100%) x-ray protection and effective performance for gamma-ray shielding at energies up to 15 MeV. The current work creates new opportunities for the low-temperature, simple, effective, and affordable synthesis of nanomaterials for usage in display device applications and X-ray/gamma-ray shielding.
