Abstract: The present work deals with the study of shielding ability of UP-Bi2O3 polymer composites for gamma rays of energy 0.662 MeV using a gamma ray spectrometer. The various shielding parameters such as linear and mass attenuation coefficients, half value and tenth value layer thickness, and mean free path have been evaluated for the composites. The attenuation coefficients of the composites have also been evaluated theoretically using the computer code XCOM and WinXCOM. The results show that, the shielding performance increases with increase in the filler concentration. The highest filled composite exhibits excellent shielding ability and is comparable to that of the conventional shielding materials. The theoretical and experimental values are in good agreement.
