Study of Gamma Ray Exposure Buildup Factor for Some Ceramics with Photon Energy, Penetration Depth and Chemical Composition

Abstract

Gamma ray exposure buildup factor for some ceramics such as boron nitride (BN), magnesium diboride (MgB 2 ), silicon carbide (SiC), titanium carbide (TiC) and ferrite (Fe 3 O 4 ) has been computed using five parametric geometric progression (G.P.) fitting method in the energy range of 0.015 to 15.0 MeV, up to the penetration of 40 mean free path (mfp). The variation of exposure buildup factors for all the selected ceramics with incident photon energy, penetration depth, and chemical composition has been studied.
