Transmission through matter
X-ray attenuation in air
The calculation is based on the extrapolation function derived from the data presented inWm. J. Veigele "X-Ray Attenuation Cross Sections of Air between 0.1 keV and 1 MeV", Journal of Applied Physics, v.41, 1970, pp.3178
X-ray attenuation in condensed matter
Intensity transmission or transmission coefficient T = exp( -μd)Intensity loss A = 1 - T
Phase shift φ = 2πδd/λ
