Artigo IPEN-doc 29810 k0‑IPEN2023 - DIAS, MAURO da S.; SEMMLER, RENATO; KOSKINAS, MARINA F.; MOREIRA, DENISE S.; YAMAZAKI, IONE M.; BRANCACCIO, FRANCO; BARROS, LIVIA F.; RIBEIRO, RAFAEL V.; MORAIS, THALES S.L. deA software package for INAA (Instrumental Neutron Activation Analysis), developed at the Nuclear Metrology Laboratory of the IPEN-CNEN/SP, called k0-IPEN, is described. The package consists of a main program linked to nine subprograms designed to perform automatically most of the tasks necessary in order to obtain the mass fractions of the irradiated samples. External efficiency curves calculated by the Monte Carlo code MCNP6 can be read to extend the calibration curve to source to detector distances where only a few experimental points are available. Covariance analysis was used in all steps of the calculation. The validation of the code was tested in an intercomparison sponsored by the IAEA.Artigo IPEN-doc 27118 Primary standardization and determination of gamma ray emission intensities of Ho-1662020 - YAMAZAKI, I.M.; KOSKINAS, M.F.; MOREIRA, D.S.; SEMMLER, R.; BRANCACCIO, F.; DIAS, M.S.The procedure followed by the Nuclear Metrology Laboratory (LMN) at the IPEN-CNEN/SP, in S~ao Paulo, for the primary standardization of 166Ho is described. The activity of 166Ho was determined by the efficiency extrapolation technique applied to a 4πβ(PC)-γ coincidence system using a gas flow proportional counter in 4π geometry coupled to a 76 x 76 mm NaI(Tl) crystal. The results for the γ-rays intensities at 80.57 and 1379.45 keV were 0.0651(11) and 0.00904(11), respectively.Artigo IPEN-doc 26420 Data analysis software package for radionuclide standardization with a digital coincidence counting system2020 - BRANCACCIO, F.; DIAS, M.S.; KOSKINAS, M.F.; MOREIRA, D.S.; TOLEDO, F. deThe Nuclear Metrology Laboratory (LMN) – IPEN, S~ao Paulo, Brazil – developed a Digital Coincidence System (DCS), based on the Coincidence Counting Methodology, in order to improve its capabilities in radionuclide primary-standardization. Digital process is implemented in two steps: data-acquisition (a set of measurements) and offline software data-analysis and calculation. The present work shows the basics of the data-acquisition unit (Software Coincidence System – SCS), describes the DCS’ data-analysis process and the initial approaches chosen for the implementation of the software package (Coincidence Analyzing Task – CAT). 152Eu standardization, performed for DCS testing, software expansion and validation, is briefly discussed.Artigo IPEN-doc 23950 Standardization of 59Fe by 4π(PC)β–γ software coincidence system2016 - KOSKINAS, M.F.; POLILLO, G.; BRANCACCIO, F.; YAMAZAKI, I.M.; DIAS, M.S.The procedure for the standardization of 59Fe using a 4π(PC)β–γ software coincidence system is de-scribed. The standardization was performed with an experimental setup consisting of a thin window gas- flow proportional counter (PC)in4π geometry coupled to a NaI(Tl) scintillator and to a HPGe detector. The data acquisition was carried out by means of a Software Coincidence System (SCS).The beta efficiency was changed by using Collodion films Colldion films andaluminum foils as external absorbers.Artigo IPEN-doc 20063 Disintegration rate, gamma-ray emission probabilities and metastable half-life measurements of sup(67)Ga2014 - DIAS, M.S.; BRANCACCIO, F.; TOLEDO, F.; KOSKINAS, M.F.Artigo IPEN-doc 19655 Improvements in the Monte Carlo code for simulating 4'pi'beta'(PC)-'gamma' coincidence system measurements2013 - DIAS, M.S.; TAKEDA, M.N.; TOLEDO, F.; BRANCACCIO, F.; TONGU, M.L.O.; KOSKINAS, M.F.Artigo IPEN-doc 09406 Sistema eletronico para automatizacao de medidas de correntes produzidas por camaras de ionizacao2002 - BRANCACCIO, F.; DIAS, M.S.Artigo IPEN-doc 10460 Automatic system for ionizing chamber current measurements2004 - BRANCACCIO, F.; DIAS, M.S.; KOSKINAS, M.F.Artigo IPEN-doc 13768 Standardization of sup(18)F by means of 4 'pi' (PS) 'beta' - 'gamma' plastic scintillator coincidence system2008 - BACCARELLI, AIDA M.; DIAS, MAURO S.; KOSKINAS, MARINA F.; BRANCACCIO, FRANCOArtigo IPEN-doc 16121 Primary standardization of sup(57)Co2010 - KOSKINAS, MARINA F.; MOREIRA, DENISE S.; YAMAZAKI, IONE M.; TOLEDO, FABIO de; BRANCACCIO, FRANCO; DIAS, MAURO S.
