Photon Attenuation coefficient test


Short description: the simulation calculates the total attenuation coefficient of photons with energy up to 10 GeV in water. The coeffient is also calculated for individual processes (Rayleigh scattering, photoelectric effect, Compton scattering and gamma conversion).
