Tables of X-Ray Mass Attenuation Coefficients for 87 Elements at Selected Wavelengths
Tables of x-ray mass attenuation cross sections have been prepared for 87 elements with atomic numbers between one and 94 at 99 selected wavelengths of interest to spectroscopists, microprobe users, diffraction workers, etc. The tables were derived from a recent x-ray cross section compilation covering the energy range 0.1 keV to 1 MeV. A brief description is given of the assumptions and methods used in preparing the original compilation to point out the limitations of the derived tables.

- 2.We follow the suggestion of the International Commission on Radiation Units and Measurement and use “total attenuation coefficient” to denote the total photon interaction cross section and use “absorption coefficient” for photoelectric absorption plus the absorption part of incoherent scattering.Google Scholar
- 5.The tables presented here are extracted from a more extensive set of tables to be published by Kaman Sciences. The more extensive tables list attenuation and absorption coefficients for 87 elements at 272 emission wavelengths, including 38 Ka lines, 31 Kß lines, 73 Lalines, 72 Lß1lines, 29 Ma lines, and 29 Mß lines. Information on the extended tables may be obtained from the authors.Google Scholar
