Abstract
The reduction in the intensity of an x-ray beam as it passes through gases and vapors, especially those of the heavy elements, is caused by several processes: the ionization and excitation of the atoms, dispersion of the beams, and the formation of electron—positron pairs when the photon energy is high.
