The present wok deals with the shielding properties of polymer composites using neutrons and gamma rays emitted from 252Cf neutron source. Polymer composites with different Aluminum oxide ratio (x = 0, 10, 20, 30, 40 and 50 wt. %) have been prepared. The shielding parameters for the prepared samples have been determined using the narrow beam transmission method. The transmitted neutrons and gamma rays was measured using neutron/gamma spectrometer incorporate stilbene organic scintillator.

In this study, the shielding parameters for Glycidyl methacrylate with different ratio of Barite and Boron Carbide Polymer composites were theoretically calculated. The mass attenuation coefficients have been calculated at the photon energy range of 1 keV–1 GeV by using XCom program. The obtained data will be used to calculate the effective atomic number (Zeff) and effective electron density (Neff) for the same range of energy. The macroscopic fast neutron removal cross-sections have also been calculated.
