Preparation and characterization of a new GdO-epoxy composite for neutron shielding applications.

The current study aims to introduce a new polymeric composite consisting of epoxy resin as the matrix and gadolinium oxide (GdO) as the neutron adsorption ingredient. The shielding performance of the composite was assessed by neutron attenuation experiments with an Am-Be source and polyethylene moderator. The results of these experiments showed an appreciable agreement with the Monte Carlo simulations.

Study on physico-mechanical and gamma-ray shielding characteristics of new ternary nanocomposites.

In this study, a series of "Epoxy-Clay-PbO" nanocomposites under the name of ECPNCs were prepared by the molding method, and their physico-mechanical properties were investigated by different techniques. Focus of the work, was on the shielding ability of the ECPNCs for the gamma rays, emitted from Ir-192, Cs-137 and Co-60 with a wide range of energy. Scanning electron microscopy, and X-ray diffractometry demonstrated that clay platelets were fully exfoliated, and the PbO particles were homogenously distributed in the polymeric matrix.
