This work is an attempt to develop flexible radiation shielding based on a blend of polymethyl methacrylate (PMMA)/polyvinyl acetate (PVAc) and LaFeO nanoparticles (NPs). LaFeO and LaFeO/PMMA/PVAc were made using simple chemical techniques. A high-resolution transmission electron microscope (HR-TEM) and X-ray diffraction (XRD) showed that well-crystallized LaFeO NPs with particles 79 nm in size and an orthorhombic shape were obtained.

XRD patterns and FTIR spectra demonstrated that the polymer composite sheets were successfully developed. The morphology and elemental composition were addressed using SEM images and EDX spectra.

- The study explores the properties of polyvinyl chloride (PVC) that contains varying amounts of bismuth vanadate (BiVO) as a non-toxic alternative to lead for radiation shielding.
- It confirms the successful integration of BiVO into PVC through various characterization methods such as XRD, FTIR, TEM, SEM, and EDX.
- Results suggest that increasing BiVO content improves radiation protection efficiency, highlighting the potential for developing lead-free, sustainable polymer nanocomposites for shielding applications.
