Management of disused sealed sources received by the Brazilian Center for Development of Nuclear Technology - CDTN, MG

The increasing use of radioactive sources in Brazil brought as a consequence the increased number of disused sources because, after the withdrawal of the service, the sources are discarded by users of radioisotopes. These sources have been forwarded to the research institutes of the CNEN, among them CDTN - Brazilian Center for Development of Nuclear Technology -, who have received a significant amount of them, including more intense activity sources, such as from the teletherapy. For effective control of the sources, the compliance of the CNEN - Brazilian Nuclear Energy Commission - and the recommendations of IAEA -International Atomic Energy Agency - implemented a management system that enables the monitoring of the entire process, from the initial contact to the delivery of supplies to its appropriate packaging. This paper describes the progress that has been made
