Artigo IPEN-doc 23952 Traceability from governamental producers of radiopharmaceuticals in measuring 18F in Brazil2016 - OLIVEIRA, A.E.; IWAHARA, A.; SILVA, C.J.; CRUZ, P.A.L.; POLEDNA, R.; SILVA, R.L.; LARANJEIRA, A.S.; DELGADO, J.U.; TAUHATA, L.; LOUREIRO, J.S.; TOLEDO, B.C.; BRAGHIROLLI, A.M.S.; ANDRADE, E.A.L.; SILVA, J.L.; HERNANDES, H.O.K.; VALENTE, E.S.; DALLE, H.M.; ALMEIDA, V.M.; SILVA, T.G.; FRAGOSO, M.C.F.; OLIVEIRA, M.L.; NASCIMENTO, E.S.S.; OLIVEIRA, E.M.; HERRERIAS, R.; SOUZA, A.A.; BAMBALAS, E.; BRUZINGA, W.A.Since the inception of its proficiency test program to evaluate radionuclide measurement in hospitals and clinics, the National Metrology Laboratory of Ionizing Radiation-LNMRI, that represents Brazilian National Metrology Institute (NMI) for ionizing radiation has expanded its measurement and calibration capability. Requirements from the National Health Surveillance Agency from Ministry of Health (ANVISA), to producers of radiopharmaceuticals provided an opportunity to improve the full traceability chain to the highest level. Fluorodeoxyglucose (FDG-18F) is the only radiopharmaceutical simultaneously produced by all Brazilian radiopharmaceutical production centers (RPCs). By running this proficiency test, LNMRI began to provide them with the required traceability. For evaluation, the ratio of RPC to reference value results and ISO/IEC17043:2010 criteria were used. The reference value established as calibration factor on the secondary standard ionization chamber was obtained from three absolute measurements systems, and routinely confirmed in each round of proficiency test by CIEMAT/NIST liquid scintillation counting. The γ-emitting impurities were checked using a High-Purity Germanium (HPGe) detector. The results show that Brazilian RPCs are in accordance with (accuracy within 710%) the Brazilian standard for evaluation of measurements with radionuclide calibrators (CNEN NN 3.05., 2013). Nevertheless, the RPCs should improve the methodology of uncertainty estimates, essential when using the statistical criteria of ISO/IEC 17043 standard, in addition to improving accuracy to levels consistent with their position in the national traceability chainPublicação IPEN-doc 03742 Projeto e construcao de detectores metalicos halogenados tipo Geiger-Mueller com janela de mica1990 - GORSKI, M.S.; BRUZINGA, W.A.Resumo IPEN-doc 16609 Sodium fluoride-18F: preparation and quality control2008 - SOUZA, A.A.; HERRERIAS, R.; BRUZINGA, W.; NEGRINI, A.; FUKUMORI, N.T.O.; MATSUDA, M.M.N.; SCIANI, V.; MENGATTI, J.; BARBOZA, M.F.Artigo IPEN-doc 11185 Synthesis and quality control of sup(18)F-FDG at IPEN-CNEN/SP2005 - BARBOZA, M.F.; SCIANI, V.; HERRERIAS, R.; SUMIYA, L.C.; BRUZINGA, W.; GOES, M.M.; BAMBALAS, E.; MARIALVA NETO, A.A.; SOUZA, A.A.; PIRES, J.A.; MATSUDA, H.; MENGATTI, J.; SILVA, C.P.G.Artigo IPEN-doc 05527 Desenvolvimento de um sistema calorimetrico para dosimetria de gases em fluxo continuo, irradiados com feixe de eletrons1994 - CAMPOS, C.A.; BANADOS PEREZ, H.E.; VIEIRA, J.M.; POLI, D.C.R.; SOMESSARI, S.L.; BRUZINGA, W.; ALBANO, G.C.Artigo IPEN-doc 01941 Desenvolvimento e caracterizacao de um absorvedor de zirconio com porosidade controlada1992 - LIMA, L.F.C.P.; GORSKI, M.S.; AMBROZIO FILHO, F.; SOUSA, V.A.; BRUZINGA, W.A.; CASTRO, A.R.M.Artigo IPEN-doc 04612 Contribuicao ao desenvolvimento de detectores metalicos Geiger-Muller halogenado com janela de mica1990 - GORSKI, M.S.; BRUZINGA, W.A.; LIMA, W.Artigo IPEN-doc 06592 Determinacoes de vazoes de efluentes nos canais da Companhia Siderurgica Nacional - CSN, em Volta Redonda, RJ, com utilizacao de tracador radioativo1999 - BAMBALAS, E.; BRUZINGA, W.A.; ROCCA, H.C.C.; AOKI, P.E.; MIRANDA, M.A.M.; SANTOS, N.J.Artigo IPEN-doc 02703 Caracterizacao do cristal cintilador CsI(Tl) desenvolvido no IPEN-CNEN/SP1995 - PEREIRA, M.C.C.; HAMADA, M.M.; MADI FILHO, T.; CALVO, W.A.P.; BRUZINGA, W.A.; VIEIRA, J.M.; MESQUITA, C.H.Artigo IPEN-doc 04947 Desenvolvimento de molde metalico para a fabricacao de plastico cintilador de grande volume1997 - CALVO, W.A.P.; VIEIRA, J.M.; RELA, P.R.; BRUZINGA, W.A.; ARAUJO, E.P.; COSTA JUNIOR, N.P.; HAMADA, M.M.
