Fabrication of polymeric shields to attenuation ionizing radiation and a flame retardant supported by nano-bismuth oxide prepared by co-deposition.

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 BiO (NaCO) retardant the flame much better than supported by BiO (NaOH). Finally, the quality of the protective shields increased as the energy of the photons of the ionizing rays decreased.
