Resumo
Several radioisotopes are produced at Instituto de Pesquisas Energéticas e Nucleares for the use in medical
treatments, including the activation of 192Ir sources. These sources are suitable for brachytherapy
treatments, due to their low or high activity, depending on the concentration of 192Ir, easiness to
manufacture, small size, stable daughter products and the possibility of re-utilization. They may be used
for the treatment of prostate, cervix, head and neck, skin, breast, gallbladder, uterus, vagina, lung, rectum,
and eye cancer treatment. In this work, the use of some 192Ir sources was studied for the treatment of
esophagus cancer, especially the dose determination of important structures, such as those on the
mediastinum. This was carried out utilizing a FASH anthropomorphic phantom and the MCNP5 Monte
Carlo code to transport the radiation through matter. It was possible to observe that the doses at lungs,
breast, esophagus, thyroid and heart were the highest, which was expected due to their proximity to the
source. Therefore, the data are useful to assess the representative dose specific to brachytherapy
treatments on the esophagus for radiation protection purposes.
