Abstract

Calculations on shielding are required for building a gamma ray radiography exposure room to ensure that the workers are exposed to radiation. The linear attenuation coefficient ( ) is a measurement used to evaluate the radiation diffusion and absorption characteristics of a medium. Despite the fact that, as radiation moves through a medium, its absorption is influenced by the radiation wavelength as well as the thickness and composition of the medium, the linear absorption coefficient is crucial in the interaction of radiation with matter. This study used a variety of materials as a shield for a gamma radiation source of  emitted by Cs-137. The results obtained through using a gamma source with a scintillation counter showed that the half-value thickness (HVT) for glass and aluminum were 3.57 cm and 3.39 cm, respectively, while for standard materials (concrete, iron, and lead) were 2.98 cm, 1.195 cm, and 0.58 cm, respectively.
