Background: This study investigated the γ-rays shielding properties of some building materials in Sudan has been investigated. Materials and Methods: Photons attenuation coefficients and half value layer (HVL) were experimented using Cs-137 and Co-60 sources.  The measurements were performed to gauge the intensity of radiation when performed unshielded, the specific thickness of selected samples was examined, using an ion chamber placed at 2 meters from Cs-137 and Co-60. Results: The results indicated that the linear attenuation coefficient (µ) possesses a linear relationship with the corresponding densities of the samples studied and inversely with photon energy. HVL was directly proportional with photon energy. Conclusion: As a result of this evaluation the study concluded that selected samples were suitable as shielding material for gamma radiation in Sudanese laboratories.
Keywords: γ-radiation, attenuation coefficient, half value layer, shielding, building materials.
