摘要：

For the transport calculation of gamma rays including bremsstrahlung, an improvement is made in the PALLAS-PL, SP discrete ordinates direct-integration code to enable evaluation of bremsstrahlung. Comparisons of PALLAS calculations with experiments are presented in this paper to test the validity of this code and method. Also presented are calculations of buildup factors and of energy spectra, including the contribution of bremsstrahlung, for a plane monodirectional beam of 8-Mev gamma rays normally incident on lead and on tungsten.
