The research of X-ray and gamma radiation absorption by layered structures

Abstract

It is investigated the passage of X-ray and gamma radiation through assembly consisting of layers of materials with different atomic numbers. It was experimentally measured and calculated in GEANT the spectra of radiation, passed through the assembly. Various spectra of the incident radiation as well as combinations of materials with different atomic numbers and thicknesses were used. Coefficients of Кs and Кe that characterize the passage of particles through heterogeneous layers were defined. Кs and Кe change sign with increasing of photon energy and growth with increase of the plates thickness.
