Water quality - Radon-222 - Part 2 : test method using gamma-ray spectrometry

ISO 13164-2:2013 specifies a test method for the determination of radon-222 activity concentration in a sample of water following the measurement of its short-lived decay products by direct gamma-spectrometry of the water sample.The radon-222 activity concentrations, which can be measured by this test method utilizing currently available gamma-ray instruments, range from a few becquerels per litre to several hundred thousand becquerels per litre for a 1 l test sample.This test method can be used successfully with drinking water samples. The laboratory is responsible for ensuring the validity of this test method for water samples of untested matrices.An annex gives 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 pour déterminer l’activité volumique du 222Rn dans un échantillon d’eau par la mesure des descendants à vie courte du 222Rn par spectrométrie gamma directe d’un échantillon d’eau (voir Annexe A). Les valeurs d’activité volumique du 222Rn, qui peuvent être mesurées par cette méthode d’essai à l’aide d’instruments de spectrométrie gamma actuellement disponibles, sont comprises entre quelques becquerels par litre et plusieurs centaines de milliers de becquerels par litre pour une prise d’essai de 1 l. Cette méthode d’essai peut être 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. L’Annexe B donne une indication sur les conditions de comptage nécessaires pour obtenir la sensibilité requise pour la surveillance de l’eau potable.

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!
