“…Polymer composites find their place in several fields such as biomedical, automobile industry, aerospace, construction applications, electrical, and electronic field, sanitary applications, sports and many more. In addition, polymer composites are finding their application in nuclear science and technology especially in radiation protection . The common shielding material in practice, for protecting from the radiation exposure is lead, but, do lack in chemical stability, heaviness, flexibility, and moreover is toxic.…”

Unsaturated Polyester resin is reinforced with Bi 2 O 3 up to 60% filler weight. The effect of bismuth oxide on gamma shielding ability of the composites is studied in terms of attenuation parameters using Ba-133, Cs-137, and Co-60 gamma ray sources. The results reveal that, the shielding property of the composite material increases with increase in the filler concentration and decreases with energy. The HVL, TVL, and relaxation length of the composites are found to decrease with increase in the filler concentration. It is found that, the shielding ability of 60% filled polymer composite is comparable to that of barite at low energy. The above polymer composite performs well at all energies and can act as an excellent gamma radiation shield for low energies and also proved to be light weight when compared to the conventional shielding materials. Thus, the gamma shielding ability of the UP resin is enhanced due to the addition of Bi 2 O 3 .

“…Ionizing radiation is very dangerous to human health, such as neutrons, so it was necessary to assess these risks and determine the level of exposure to this radiation and to develop the technologies to protect against this radiation [1]. Neutron shielding is complex because neutrons interact with matter only through nuclei, so they do not stop easily through matter, and can travel large distances through most materials without scattering or absorbing.…”

In this paper ,Shielding parameters of fast neutrons like removal cross section , half thickness , and mean free path were calculated for polymer composite whish consisted of paraffin wax as basic material (P) with various reinforced materials (B, B2O3, Fe2O3, W, Clay) with different reinforced concentration (5, 15, 25, 35, 45) % . Results have been shown that , with increasing the reinforced materials concentrations , removal cross section increases while half thickness and mean free path decreased.

Novel radiation shielding nanocomposites based on a conducting polymer were fabricated and investigated to determine their abilities in attenuation of X-rays. Polypyrrole/Pb nanocomposites were prepared through chemical reduction of lead salt by a facile solution-phase method using t-BuOLi-activated LiH and in situ chemical polymerization of pyrrole in the presence of dodecyl benzene sulfonic acid as dopant and surfactant and iron chloride as the oxidant. The morphology, composition, and electrical conductivity of resulting products were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis, energy-dispersive X-ray spectroscopy, fourier transform infrared spectroscopy, and standard four-wire technique, respectively. In order to evaluate capability of nanocomposites in radiation shielding, X-ray photon interaction parameters such as linear attenuation coefficient, attenuation percentage, and half-value thickness were determined for the samples with different Pb loadings and thicknesses, at photon energies of 13. 95, 17.74, 20.08, 26.34, and 59.50 keV. The investigation was carried out to explore the potential of polypyrrole/Pb nanocomposites as thin and light-weight radiation shielding materials.
