Zusammenfassung:The results of the preparation of protective shields from ionizing radiation, flame retardant from pure epoxy supported by nano-bismuth oxide, show that the protective shields supported by nanoparticles improve the attenuation properties, the thermal stability, the flame retardancy and mechanical properties. Also, the polymeric shield supported by Bi2O3 (Na2CO3) retardant the flame much better than supported by Bi2O3 (NaOH). Finally, the quality of the protective shields increased as the energy of the photons of the ionizing rays decreased. •Nano-magnetite was created, and the effect of utilizing several types of bases on the particle size was investigated.•Protective shields from ionizing radiation and flame retardant using nanoparticles as a support phase for composites.•Measuring the attenuation properties of ionizing radiation prove the quality of manufactured shields.
