Calculation of Dose Gamma Ray Buildup Factor

Abstract

The dose gamma ray buildup factor for different materials (Al, Cu and Pb) up to had been calculated using computer programs, which were constructed to calculate this factor for different materials using Taylor’s formula for point isotropic source .The programs had been designed to work with any atomic number and energy by adapting Lagrange interpolation method according to the studied factors (thickness of the shielding, energy of the gamma ray and atomic number of the shield (.
