摘要: Abstract In this study, gamma ray buildup factors were investigated for conventional shielding materials such as lead, iron, concrete, and tungsten based on standard formulations in order to understand the variations between different formulations. The exposure 1 MeV rays concrete thicknesses beyond 40 mean free paths computed using modified geometric progression fitting formula compared with previously reported data. For first time, at energies from 15 keV 15 MeV a penetration depth paths.
