The package "XRayAttenuation.m" defines functions which provide an interpolation of the tables of NIST report 5632, "Tables of XRay Mass Attenuation Coefficients and Mass EnergyAbsorption Coefficients 1 keV to 20 MeV for Elements Z = 1 to 92 and 48 Additional Substances of Dosimetric Interest," by J. Hubbell and S.M. Seltzer. Based on this interpolation, additional functions provide xray attenuation and absorption mean free paths and xray fractional transmission and absorption in these 140 materials, as well as in homogenous mixtures and in chemical compounds based on these materials. Functions to convert xray wave length and frequency to energy are also included. The notebook "XRayAttenuation Tutorial.nb" describes briefly the attenuation and absorption of xrays in matter and demonstrates the use of the package.
