X-ray absorption in matter. Reengineering XCOM
Radiation Physics and Chemistry, 2001Abstract A Windows version of XCOM, the well-known program for calculating X-ray and gamma-ray attenuation coefficients and interaction cross sections, has been developed. The new program, called WinXCom, has an improved user interface.

XCOM intrinsic dimensionality for low-Z elements at diagnostic energies
Medical Physics, 2012To determine the intrinsic dimensionality of linear attenuation coefficients (LACs) from XCOM for elements with low atomic number (Z = 1-20) at diagnostic x-ray energies (25-120 keV). H(0) (q), the hypothesis that the space of LACs is spanned by q bases, is tested for various q-values.Principal component analysis is first applied and the LACs are ...

Abstract The total mass attenuation coefficients (μ/ρ) of oxide dispersion strengthened (ODS) steels have been investigated by using Geant4 simulation toolkit at energies ranging from 0.01 MeV to 100 GeV. Moreover, Geant4 is applied to further study on the partial mass attenuation coefficient of three main interactions including photoelectric effect,

The mass attenuation coefficients, mu/rho of some thermoluminescent dosimetric materials with potential applications as personnel dosimeters, have been investigated using Geant4 simulation toolkit. Appreciable variations are noted for the mu/rho values by changing the photon energy and chemical compositions.
