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 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.
