Resumo
A new Iridium-192 seed for brachytherapy is under development. Specific dose rate contribution by two different
factors were evaluated: the effect from movement of the core in the free space within the seed and the effect of
the end-weld thickness variation. Both were investigated through use of the Monte Carlo radiation transport code
MCNP6 and an in-house routine programmed with MATLAB. Differences greater than 15% compared to results
from the nominal seed were found near the source, indicating a significant dose variation.
