Resumo
Considering that the risks associated with ionising radiation are
dependent on the characteristics of the exposed individual and that the
structures and sizes of the human body vary considerably as a function of
gender, efforts must be made in order to study the effective and absorbed doses
in thoracic radiological examinations. taking into account the special features
of the female anatomy. In this work, the Monte Carlo code Monte Carlo
N-Particle eXtended (MCNPX) and the Female Adult voXel (FAX) phantom
are combined in order to investigate how the effective and absorbed doses
vary in thoracic radiological examinations. The results suggest that different
precautionary measures should be taken depending on the chosen geometric
projection and that the application of higher voltages to the X-ray tube appears
to be an alternative to reduce the effective and absorbed doses.
