Artigo IPEN-doc 20270 Determination of scaling factors to estimate the radionuclide inventory of wastes from the IEA-R1 research reactor2015 - TADDEI, M.H.T.; MACACINI, J.F.; VICENTE, R.; MARUMO, J.T.; TERREMOTO, L.A.A.Regulations for transfer and final disposal of radioactive waste require that the inventory of radionuclides for each package enclosing such waste must be estimated and declared. In this work, the scaling factor methodology was applied successfully to estimate the inventory of radionuclides in spent ion-exchange resins and spent activated charcoal, both with low and intermediateactivity level, from the IEA-R1 nuclear research reactor. Scaling factors or correlation functions were obtained linking the activity concentrations of 15 difficult to measure nuclides with two gamma-rays emitting key nuclides, reducing exposure to ionizing radiation, contamination risks and operational costs.Artigo IPEN-doc 16875 Determination of sup(55)Fe and sup(63)Ni in spent ion-exchange resins from the IEA-R1 reactor (IPEN-CNEN/SP)2011 - TADDEI, MARIA H.T.; VICENTE, ROBERTO; FERREIRA, MARCELO T.; MARUMO, JULIO T.; TERREMOTO, LUIS A.A.Artigo IPEN-doc 17164 Correlation of container exposure rates with radioisotopic inventory of waste2011 - SOUZA, DAIANE C.B. de; PERRELLA, ERICO S.; TADDEI, MARIA H.T.; VICENTE, ROBERTOArtigo IPEN-doc 16866 Characterization of radioactive spent ion-exchange resins2011 - TADDEI, MARIA H.T.; MARUMO, JULIO T.; TERREMOTO, LUIS A.A.; VICENTE, ROBERTOArtigo IPEN-doc 19080 Determination of sup(63)Ni and sup(59Ni in spent ion-exchange resin and activated charcoal form the IEA-R1 nuclear research reactor2013 - TADDEI, M.H.T.; MACACINI, J.F.; VICENTE, R.; MARUMO, J.T.; SAKATA, S.K.; TERREMOTO, L.A.A.Artigo IPEN-doc 18877 A comparative study using liquid scintillation counting and X-ray spectrometry to determine sup(55)Fe in radioactive wastes2013 - TADDEI, M.H.T.; MACACINI, J.F.; VICENTE, R.; MARUMO, J.T.; SAKATA, S.K.; TERREMOTO, L.A.A.Artigo IPEN-doc 18878 Determination of long-lived radionuclides in radioactive wastes from the IEA-R1 nuclear research reactor2013 - TADDEI, M.H.T.; VICENTE, R.; MARUMO, J.T.; SAKATA, S.K.; TERREMOTO, L.A.A.
