Description

The paper presents the results obtained in the standardization of 65 Zn by using the 4πPC-γ coincidence installation of the Istituto di Metrologia delle Radiazioni Ionizzanti (INMRI), C.R.Casaccia, ENEA, Italy, by the efficiency extrapolation method. The basic relations existing between 4πPC efficiencies, coincidence equations, as well as the experimental results obtained in various conditions are presented. Two sets of measurements were carried out on the 4πPC channel: detection of the radiations from (K+L) electron capture-β+ and from K electron capture-β+. The measurements on the gamma channel were made by ensuring linearity extrapolation conditions, by measuring the 1115. 6 keV quanta alone and by approximate accomplishment of linearity condition. The obtained values of activity were compared with the value determined by using a calibrated CENTRONIC IG11/20A ionization chamber. (authors)
