glass ball SRD 7 NIST Electron and Positron Stopping Powers of Materials (PC database for purchase)  Keywords for Database
The EPSTAR database provides rapid calculations of stopping powers (collisional, radiative, and total), CSDA ranges, radiation yields and density effect corrections for incident electrons or positrons with kinetic energies from 1 keV to 10 GeV, and for any chemically defined target material.
glass ball SRD 126 X-Ray Attenuation and Absorption for Materials of Dosimetric Interest (Web, free access)  Keywords for Database
Tables and graphs of the photon mass attenuation coefficient and the mass energy-absorption coefficient are presented for all of the elements Z = 1 to 92, and for 48 compounds and mixtures of radiological interest. The tables cover energies of the photon (x-ray, gamma ray, bremsstrahlung) from 1 keV to 20 MeV.
