摘要：

Quick and relatively simple procedures were incorporated into the Monte Carlo code DETEFF in order to consider the escape of Bremsstrahlung radiation and secondary electrons. The relative bias in efficiency values was thus reduced for photon energies between 1500 and 2000 keV, without any noticeable increment of the simulation time A relatively simple method was also included to consider the rounding of detector edges The validation studies showed relative deviations of about 1% in the energy range 10-2000 key.
