Abstract
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.
期刊介绍：
Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment.
The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria.
Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
