Radiation shielding is the process of reducing the amount of radiation exposure to a particular area or individual. This is important in many applications, including medical imaging, nuclear power plants, and space exploration. In Saudi Arabia, where nuclear power plants are being built, radiation shielding is an important consideration to ensure the safety of workers and the public. The limit for radiation shielding is not a fixed value but depends on the specific application and the type of radiation being shielded. There are several factors that affect the effectiveness of radiation shielding, including the thickness and composition of the shielding material, the energy and type of radiation, and the distance between the radiation source and the shielded area. In general, the effectiveness of radiation shielding is determined by the material's ability to absorb or scatter radiation. This is measured by the material's linear attenuation coefficient (LAC), which is the fracti
