Resumo
The design of radiation bunkers is based on the existence of thick walls and mazes, ducts with
bends, in penetration points. These mazes tend to have traditional designs with three or more
bends with plain finished walls, penetrating the bunker walls with low radiation transmission
rate. The traditional designs require wide installation footprints and long transport systems,
following the respective maze. Reducing the radiation transmission of each bend, it's possible
to reduce the amount of curves and the length of their ducts, or legs, to reach the desired maze
radiation transmission rate. Minimizing the maze legs can reduce significantly the costs of the
installation construction and maintenance. The proposed maze modifications, effective for
gamma and neutron fluxes, have the radiation transmission many times lower than
a traditional maze with the same duct number and lengths. The main purpose of this work is
to show that it is possible to enhance the maze efficiency to reduce the radiation transmission
adopting radiation "traps". Each "trap" have to be optimized for the radiation source and maze
section. As example, the efficiency enhancement of one of these modifications for gamma
radiation is determined by comparative simulations. The results of Monte Carlo simulations
are presented in this work.
