Resumo IPEN-doc 26564 Preliminary proposal for radioactive liquid waste management in a brachytherapy sources production laboratory2011 - SOUZA, CARLA D.; VICENTE, ROBERTO; ROSTELATO, MARIA E.C.M.; ZEITUNI, CARLOS A.; MOURA, JOÃO A.; MOURA, EDUARDO S.; MATTOS, FABIO R.; FEHER, ANSELMO; COSTA, OSVALDO L. da; VIANNA, ESTANISLAU B.; CARVALHO, LAERCIO de; KARAN JUNIOR, DIBMalignant 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.Resumo IPEN-doc 02501 Estudo de elementos-tracos presentes no material particulado suspenso na Represa do Funil-Rezende-RJ1984 - CAMPOS, M.M.; VASCONCELLOS, M.B.A.; CARVALHO, J.L.
