Water quality - Radon-222 - Part 3 : test method using emanometry

ISO 13164-3:2013 specifies a test method for the determination of radon-222 activity concentration in a sample of water following its transfer from the aqueous phase to the air phase by degassing and its detection. It gives recommendations for rapid measurements performed within less than 1 h.The radon-222 activity concentrations, which can be measured by this test method utilizing currently available instruments, range from 0,1 Bq l−1 to several hundred thousand becquerels per litre for a 100 ml test sample.This test method is used successfully with drinking water samples. The laboratory is responsible for ensuring the validity of this test method for water samples of untested matrices.This test method can be applied on field sites or in the laboratory.Annexes A and B give indications on the necessary counting conditions to meet the required sensitivity for drinking water monitoring

La présente partie de l’ISO 13164 spécifie une méthode d’essai permettant de déterminer l’activité volumique du 222Rn dans un échantillon d’eau après son transfert de la phase aqueuse vers la phase gazeuse par dégazage et sa détection. Elle donne des recommandations concernant des mesures rapides effectuées sur une période inférieure à 1 h. Les valeurs d’activité volumique du 222Rn, qui peuvent être mesurées par cette méthode d’essai à l’aide d’instruments actuellement disponibles, sont comprises entre 0,1 Bq·l-1 et plusieurs centaines de milliers de becquerels par litre pour une prise d’essai de 100 ml. Cette méthode d’essai est utilisée avec succès sur des échantillons d’eau potable. Il appartient au laboratoire de garantir la validité de cette méthode d’essai pour des échantillons d’eau provenant de matrices non soumises à essai. Cette méthode d’essai peut être mise en œuvre sur site ou en laboratoire.

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!
