Resumo
There is a serious, and growing concern about the increased risk of the emergence of
a secondary cancer, radio-induced, associated with radiotherapy treatments. To assess the radiation
doses to organs outside the target volume, in this work, several computational exposure scenarios
were modelled, based on Monte Carlo simulation (MCNPX code). A Varian 2100c accelerator,
and a female virtual anthropomorphic phantom were used, in a simulated treatment of cervical
cancer. The determination of the dispersed dose would be important for assessing the risk in
different organs or tissues. Four treatment fields were applied, varying the gantry angle. It was
possible to observe that the conversion factors for equivalent dose were higher for the AP
projection. For the RLAT and LLAT projections, the results were similar, fact that may be
attributed to the symmetrical distributions of the organs in relation to the radiation source. The
results presented in this work showed that the computational exposure scenario provides a versatile
and accurate tool to estimate in a ready way the absorbed doses during a cervical treatment.
