Resumo
Malignant tumors are responsible for a high death rate in the entire world population (1).
Prostate cancer is the third most common among men, after skin and lung. The treatment
using permanent Iodine-125 seed are too costly, preventing the use in large scale (1) (2).
A multidisciplinary team was formed to develop a source of Iodine-125 and assemble
a national facility for local production. For the production correct implementation, a plan for
radiological protection that has the management of radioactive waste fully specified are
necessary. This work has developed an initial liquid waste management proposal.
The most important Iodine-125 liquid waste is generated in the first phase of the process,
radioactive material fixation. The initial proposal is that the waste is deposited in a 20 L
container (2 years to fill). The final activity of this container is 4.93 x 1011 Bq. According to
the discharge limits presented in the brazilian's regulation CNEN - NE - 605 - Management of
radioactive wastes in radioactive facilities (3) this waste could safely be release to the
environment in 3.97 years. In the other hand,if a minimization waste policy will be
implemented, the production could becomes more efficient and cheaper. Waste storage at 25
L containers and changing some production parameters results in 3 years waste to be
eliminated in 3.94 years. This new plan will optimize the materials used and diminished the
waste generation facilitating the management, contributing to a cheaper product.
