Application of cargo scanner systems plays critical role in the non-intrusive inspection of import, export and security controls at borders and customs. Determiningthe linear attenuation coefficient is important in identifying material type, detection capability and image quality recorded by these systems. This parameter depends on the type of material, type of radioactive source and its energy. In this study, the linear attenuation coefficient of iron sheets with thickness of 5, 10 and 15 mm were measured using a cargo scanner system equipped with a cesium 137 gamma ray source with 0.667 MeV energy. The measured values for the samples were compared with reported experimental and therorotiocal values. The results showed a good agreement with each other.
