Artigo IPEN-doc 22612 Determination of trace elements in aerosol samples by instrumental neutron activation analysis1990 - PAIVA, R.P.; MUNITA, C.J.S.; CUNHA, I.I.L.; ROMANO, J.; ALONSO, C.D.Two nuclear techniques, Energy-Dispersive X-Ray Fluorescence Analysis (EDXRF) and Instrumental Neutron Activation Analysis (INAA), were used to analyze aerosol samples collected in the city of Sao Paulo, Brazil. Na, CI, Mn, V, A1, Sm, Mo, W, La, As, Br, Sb, K, Ba, Se, Th, Cr, Rb, Ca, Fe, Ce, and Sc were determined by INAA, and A1, Si, P, S, C1, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Hg, and Pb were determined by EDXRF. A preliminary identification of the main source of the atmospheric aerosol was performed based on enrichment factor and correlation coefficient calculations.Artigo IPEN-doc 07643 Study of the thermoluminescence and optical stimulated luminescence properties of quartz crystal2001 - GOZZI, G.; COSTA, A.A.; TATUMI, S.H.; KASSAB, L.R.P.; MOMOSE, E.F.; SEPULVEDA MUNITA, C.J.A.; PAIVA, R.P.Artigo IPEN-doc 07041 Intercomparison among three activation analysis laboratories in South America2001 - SEPULVEDA MUNITA, C.J.A.; PAIVA, R.P.; OLIVEIRA, P.M.S.; MOMOSE, E.F.; PLA, R.; MORENO, M.; ANDONIE, O.; FALABELLA, F.; MUNOZ, L.; KOHNENKAMP, I.Artigo IPEN-doc 06463 Geochemical characterization of rain water particulate material on a coastal sub-tropical region in SE-Brazil1998 - SILVA FILHO, E.V.; PAIVA, R.P.; WASSERMAN, J.C.; LACERDA, L.D.Artigo IPEN-doc 04762 A contribution to the characterization of the aerosol sources in Sao Paulo1993 - PAIVA, R.P.; SEPULVEDA MUNITA, C.J.A.; CUNHA, I.I.L.; ALONSO, C.D.; ROMANO, J.; MARTINS, M.H.R.Artigo IPEN-doc 02559 Aplicacao do agente complexante tetraciclina para separacao de alguns elementos interferentes na analise por ativacao do uranio1984 - PETRAUSKAS, R.; SAIKI, M.Artigo IPEN-doc 02551 Artigo IPEN-doc 06860 Chemical characterization by INAA of Brazilian ceramics and cultural implications2000 - SEPULVEDA MUNITA, C.J.A.; PAIVA, R.P.; ALVES, M.A.; MOMOSE, E.F.; SAIKI, M.Artigo IPEN-doc 07066 Contribution of neutron activation analysis to archaelogical studies2000 - SEPULVEDA MUNITA, C.J.A.; PAIVA, R.P.; ALVES, M.A.; OLIVEIRA, P.M.S.; MOMOSE, E.F.Artigo IPEN-doc 07132 Major and trace element characterization of prehistoric ceramic from Rezende archaeological site2001 - SEPULVEDA MUNITA, C.J.A.; PAIVA, R.P.; ALVES, M.A.; OLIVEIRA, P.M.S.; MOMOSE, E.F.
