What is linear attenuation coefficient of steel?

The linear attenuation coefficient of steel varies depending on its density and the energy of the incident radiation. For gamma rays, the coefficient typically ranges from about 0.1 to 0.3 cm⁻¹ for common steel grades. This coefficient quantifies how easily radiation is absorbed or scattered by the material, indicating that steel is relatively effective at attenuating gamma radiation compared to lighter materials. Specific values can be obtained through experimental measurements or from reference tables based on the steel's composition and the radiation's energy.
