Study of gamma rays shielding parameters of some building materials used in Sudan

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