Abstract

The mass attenuation coefficient (µ/ρ), effective atomic number (ZPleff)and effective electron density (Neff) of carbon steel and stainless steels werecomputed by using the WinXcom program. The µ/ρ values are higher in the photo-electricabsorption and pair production region and approximately constant in the Compton scatteringregion. The variation in µ/ρ values is explained by partial interaction processes. Theeffective atomic numbers of the steels were also calculated by the Auto-Zeffprogram. The ZPleff values of the steels were compared with experimental resultsfor available energies and were found to be in good agreement. SS304L shows equal values ofeffective atomic number by both the methods in the region of interest. The electrondensities of the selected steels are observed to be equal and approximately constant in theCompton scattering region.
