<p>In the current work, polymethyl methacrylate (PMMA)/ x wt % ZnMoO₄ polymers were constructed to utilize in energy storage and radiation shielding fields. The structure, morphological, dielectric and radiation shielding aspects of PMMA/ x wt % ZnMoO₄ polymers were explored. X-ray diffraction (XRD) technique was employed to determine the structure and crystallite size of ZnMoO₄ filler sample. XRD and SEM techniques were employed to inspect the crystallinity and morphology of PMMA/xwt%ZnMoO₄ polymers. Using 2 wt% ZnMoO₄ filler enhanced the polymer's energy storage capacity. The energy density attained its maximum values as PMMA doped with 3 wt% ZnMoO₄. Polymer with 2 wt % ZnMoO₄ has the highest AC conductivity. Argand plots were used to discover the impact of loading ratio on the capacity of the host polymer. The linear attenuation coefficient (LAC) and mass attenuation coefficient (MAC) values at lower photon energies were increased up to 6.446&#xa0;cm⁻¹ and 4.821 cm²/g, respectively, as the polymer doped with 5 wt% ZnMoO₄. The effect of doping on the half-value layer (HVL), tenth-value layer (TVL), mean free path (MFP), effective atomic number (<i>Z</i>_eff), effective electron density (<i>N</i>_eff), effective conductivity (<i>C</i>_eff), Exposure Buildup Factor (EBF) or the Energy Absorption Buildup Factor (EABF) were explored. A higher Fast neutron removal cross-section (FNRCS) value in the loaded samples relative to the pure sample.</p>
