Abstract
The paper describes the X-ray attenuation in materials according to their atomic number, using six different materials from low atomic number to higher atomic number, Iron (Fe-26) as low atomic number, silver (Ag-47), tin (Sn-50), platinum (Pt-78), gold (Au-79) and lead (Pb-82) as high atomic number. Using the data were taken from the NIST Standard Reference Database 126. From the J. H. Hubbell and S. M. Seltzer work, a table of contents was used. Whereas The mass attenuation coefficient for the above six elements was taken and compared with each other.
Highlights
When an X-ray beam incident on an atomic target, two processes may occur; the beam may be absorbed with an ejection of electrons from the atoms, or the beam may be scattered.[1,2] Attenuation is defined as an intensity loss of incident X-rays passing through a matter

Summary
When an X-ray beam incident on an atomic target, two processes may occur; the beam may be absorbed (attenuated) with an ejection of electrons from the atoms, or the beam may be scattered.[1,2] Attenuation is defined as an intensity loss of incident X-rays passing through a matter. Where the linear absorption coefficient, μ (cm)−1 represents the average number of absorption and scattering processes that a single photon undergoes through an absorber of thickness x (cm).[3] the mass attenuation coefficient is equal to the linear attenuation coefficient to the density of the element μ /ρ (cm2/g). Many experimental measurements to determine the attenuation coefficients in solid materials have been presented [4,5]. [9] measures the mass attenuation coefficient for (Na, Mg, Al, Ca, and Fe)
