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.386-388openAccessstandardizationiron 59radioisotopesradioactivitycoincidence methodscomputer codesproportional countersradiation detectionArtigo de periódico10910.1016/j.apradiso.2015.12.023https://orcid.org/0000-0003-2478-5757https://orcid.org/0000-0001-8407-983331.49
