Photon and neutron shielding properties for scintillators used X–ray and CT imaging to investigate in this paper. Photon shielding properties of scintillators were investigated by computation for mass attenuation coefficient (mm), effective atomic number (Zeff), effective electron density (Nel) and mean free path (MFP) in the photon energy range 1 keV – 100 GeV, and buildup factor (BFs) were computed in photon energy region 15 keV – 15 MeV up to penetration depth of 40 MFP by Geometric progression (G–P) fitting formula. Lastly, removal cross–section for fast neutron (SR) of scintillators were computed. The obtained results of some scintillators were compared, in terms of mass attenuation coefficient and mean free path with standard radiation shielding concretes. The results showed that the select scintillators better radiation shielding properties than the standard shielding concrete that can be developed as photon and neutron shielding materials.
