Le présent document spécifie une méthode pour la détermination des activités volumiques alpha globale et bêta globale pour des radionucléides émetteurs alpha et bêta. Le mesurage des activités alpha globale et bêta globale n'est pas destiné à déterminer de façon absolue l'activité volumique de tous les radionucléides émetteurs alpha et bêta dans un échantillon pour essai, mais à s'…
Water quality — Gross alpha and gross beta activity — Test method using thin source deposit
This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides. Gross alpha and gross beta activity measurement is not intended to give an absolute determination of the activity concentration of all alpha and beta emitting radionuclides in a test sample, but is a screening analysis to ensure particular…
