Le présent document spécifie une méthode de détermination des activités volumiques alpha globale et bêta globale pour des radionucléides émetteurs alpha et bêta par comptage des scintillations en milieu liquide. La méthode est applicable à tous les types d''eau ayant un résidu sec inférieur à 5 g/l et lorsqu''aucune correction n''est nécessaire pour l''affaiblissement lumineux de couleur. Cette méthode couvre les radionucléides non volatils en dessous de 80 °C, étant donné que certains radionucléides gazeux ou volatils (par exemple, le radon et l''iode radioactif) peuvent être perdus lors de la préparation de la solution source.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:

  • mandatory clauses to satisfy,
  • non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document "ISO/IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents" as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
