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 10460 Automatic system for ionizing chamber current measurements2004 - BRANCACCIO, F.; DIAS, M.S.; KOSKINAS, M.F.Artigo 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.
