dc.description.abstractRadiation sealed sources have an emission that could be studied by theirs isodose surfaces. The intersection of a plan with such a surfaces is described by the dose rate contour curves. It is very common to assume that these surfaces have rotational symmetry around the longitudinal axis, and so, the contour curves have mirror symmetries. Here it is shown, by a computational simulation, that if the radioactive material inside de sealed vessel is not homogeneous, the uncertainty in dose rate measurements could achieve high values. This uncertainty value is exemplified in a iodine-125 seed source used for brachytherapy purposes.
