The various experimental arrangements and techniques from which can be obtained, particularly in the crystallographic photon energy/wavelength regime, have recently been examined and assessed by Creagh and Hubbell (1987, 1990) as part of the International Union of Crystallography (IUCr) X-Ray Attenuation Project.

The algorithm entailed use of Minkowski functionals in topologic analysis of x-ray attenuation patterns on digital mammograms. The results were compared with those of techniques based on evaluation of gray-level histograms.

Experimental X-ray attenuation cross sections for 94 elements for energies between 0.1 keV and 1 MeV were obtained for the period from 1920 through 1970. Exact photoelectric absorption values also were calculated for hydrogen.
