Artigo IPEN-doc 10878 Estudo da seguranca em eventos radiologicos com fontes seladas2003 - MITAKE, M.B.; SUZUKI, F.F.; RODRIGUES, D.L.Artigo IPEN-doc 08724 Descontaminacao de superficies na Usina de Uranio Metalico da Divisao de Processos Metalurgicos IPEN/CNEN-SP2002 - CAMBISES, P.B.S.; ALMEIDA, C.C.; VASQUES, F.M.F.; SILVA, T.M.; MITAKE, M.B.; RODRIGUES, D.L.Artigo IPEN-doc 13376 Considerations in the leakage test on sealed radioactive sources2008 - SUZUKI, FABIO F.; MITAKE, MALVINA B.; KODAMA, YASKO; LIMA, RAQUEL dos S.Artigo IPEN-doc 13377 Occupational doses involved in a radioactive waste management laboratory2008 - LIMA, RAQUEL dos S.; SILVA, AMANDA J. da; FERNANDES, IVANI M.; MITAKE, MALVINA B.; SUZUKI, FABIO F.The Radioactive Waste Laboratory (RWL) of IPEN-CNEN/SP receives, treats, packs, characterizes and stores institutional radioactive wastes, in their physical forms solid, liquid or gaseous and sealed radioactive sources, with the objective to assure an adequate level of protection to the population and to future generations and the preservation of environment. Since its creation, RWL has already received and treated about one thousand cubic meter of solid waste, eight thousand spent sealed radioactive sources from practices in industry, medicine and research, totaling more than 100 TBq. In addition, fifteen thousand radioactive lightning rods and twenty two thousand radioactive smoke detectors were received. The activities accomplished in RWL, as dismantling of lightning rods, compaction of solid wastes, decontamination of objects, waste characterization, treated waste packages rearrangement, among others, cause risks of intake and/or external exposure of workers. Requirements of radiological safety established in the regulations of the nuclear authority and international recommendations are consolidated in the RWL radioprotection plan in order to ensure the safety and protection of workers. In this paper, it was evaluated if the procedures adopted were in accordance with the requirements established in the radioprotection plan. It was also studied which activities in the waste management had substantial contribution to the occupational doses of the RWL workers in the period from 2001 up to 2006. For that, the radioprotection plan, the operational and safety procedures, the records of workplace monitoring and the individual dose reports were analyzed. It was observed that the highest individual doses resulted from operations of treated waste packages rearrangement in the facility, and none of the workers received doses above the annual limit.Artigo IPEN-doc 07074 Optimization analysis in radioactive decontamination2001 - MITAKE, M.B.; SANCHES, M.P.; CAMBISES, P.B.S.; SORDI, G.M.A.A.; RODRIGUES, D.L.Artigo IPEN-doc 07103 Resultados de resposta a emergencias radiologicas no Estado de Sao Paulo nos ultimos cinco anos2001 - MITAKE, M.B.; SUZUKI, F.F.; NICOLAU, J.R.A.; RODRIGUES, D.L.Artigo IPEN-doc 07110 Transporte de material radioativo no IPEN-CNEN/SP2001 - RODRIGUES, D.L.; SANCHES, M.P.; MITAKE, M.B.; RIBEIRO, M.S.; SUZUKI, F.F.; KODAMA, Y.Transporte é uma parte importante na indústria nuclear de todo o mundo e os registros referentes à segurança no transporte de materiais radioativos são excelentes. Os resultados extraordinários alcançados quanto aos índices de segurança resultam do esforço desenvolvido por organizações governamentais e intergovernamentais e pelo profissionalismo da indústria nuclear. Neste trabalho, apresenta-se uma visão geral das atividades relativas ao transporte de material radioativo no IPEN-CNEN/SP. Em particular, discute-se a legislação aplicada, as responsabilidades e deveres da autoridade competente. Descreve-se, também, as categorias dos materiais radioativos transportados e as exigências para o transporte seguro destes materiais radioativos.Artigo IPEN-doc 07220 Radiological emergency response in a medical waste treatment unit2000 - SUZUKI, F.F.; MITAKE, M.B.; VIANNA, E.B.; NICOLAU, J.R.A.; RODRIGUES, D.L.Artigo IPEN-doc 14059 Radioprotection considerations on the expansion project of an interim storage facility for radioactive waste2009 - BONI-MITAKE, MALVINA; SUZUKI, FABIO F.; DELLAMANO, JOSE C.Artigo IPEN-doc 12100 Common errors in transport of radioactive waste2007 - SUZUKI, FABIO F.; BONI-MITAKE, MALVINA; DELLAMANO, JOSE C.
