Resumo IPEN-doc 26562 Iridium-192 seed development for ophthalmic cancer treatment2011 - ROSTELATO, M.E.C.M.; MATTOS, F.R.; ZEITUNI, C.A.; SOUZA, C.D.; MOURA, J.A.; MOURA, E.S.; FEHER, A.; COSTA, O.L.; PELEIAS JUNIOR, F.S.; MARQUES, J.R.O.; BELFORT NETO, R.Considered a public health problem in Brazil, cancer is the second leading cause of mortality by disease, representing 13.2% of all deaths in the country [1]. Ophthalmic brachytherapy involves inserting an acrylic plate with radioactive material in the eyes of a patient for treatment of ocular tumors. This work is a partnership between Escola Paulista de Medicina - UNIFESP and the Instituto de Pesquisas Energéticas e Nucleares - IPEN for development and implementation of a cheaper therapeutic treatment for ophthalmic cancer with a iridium-192 source, to attend a greater number of patients. Iridium-192 is produced in nuclear reactor. It has a half-life of 74.2 days and decays by beta emission with average energy of 370 keV.[2,3]. The seed will be a platinum-iridium alloy core (80/20), encapsulated in a titanium tube [4]. This project will be divided into the following steps: characterization of materials by FRX (X-ray fluorescence) e EDS (Energy Dispersive Spectroscopy); iridium irradiation in the nuclear reactor IEA-R1; sealing of iridium-192 seed; leakage tests of iridium-192 source in accordance with standard ISO-9978 (radiation protection- Sealed radioactive sources- Leakage test methods) [5]; metallographic tests and measure the activity of the source. The evaluation for use in the ophthalmic treatment of cancer will be made later.Resumo IPEN-doc 22301 Study and development of a iridium-192 seed for use in ophthalmic cancer2014 - ROSTELATO, M.; SOUZA, C. de; PELEIAS JUNIOR, F.S.; ZEITUNI, C.A.; MATTOS, F.R.; BENEGA, M.A.G.; MOURA, J.A.; FEHER, A.; COSTA, O.L.Resumo IPEN-doc 22300 Study and development of a iridium-192 seed for use in ophthalmic cancer2014 - ROSTELATO, M.; SOUZA, C. de; PELEIAS JUNIOR, F.S.; ZEITUNI, C.A.; MATTOS, F.R.; BENEGA, M.A.G.; MOURA, J.A.; FEHER, A.; COSTA, O.L.Artigo IPEN-doc 19425 Influence of the profile of iridium-192 wire in measurements of quality control for use in brachytherapy2013 - COSTA, OSVALDO L.; ZEITUNI, CARLOS A.; ROSTELATO, MARIA E.C.M.; MOURA, JOAO A.; FEHER, ANSELMO; MOURA, EDUARDO S.; SOUZA, CARLA D.; SOMESSARI, SAMIR L.; PELEIAS JUNIOR, FERNANDO S.; MATTOS, FABIO R.
