Sumary

Water quality - Radium 226 - Part 2 : test method using emanometry

ISO 13165-2:2014 specifies the determination of radium-226 (²²⁶Ra) activity concentration in all types of water by emanometry. The method specified is suitable for the determination of the soluble, suspended, and total ²²⁶Ra activity concentration in all types of water with soluble ²²⁶Ra activity concentrations greater than 0,02 Bq l⁻¹. In water containing high activity concentrations of ²²⁸Th, interference from ²²⁰Rn decay products can lead to overestimation of measured levels.

Nuclear energy - Measurement of radioactivity in the environment - Water - Part 1 : measurement of radium 226 activity in water - Method by emanometry

Le présent document expose les principes et les difficultés de la détermination de l'activité du radium 226, dans tous types d'eaux par émanométrie. La méthode est applicable à tous les types d'eaux d'activités en 226Ra soluble supérieures à 0,02 Bq.L"1. Dans le cas d'eaux fortement chargées en 228Ra, l'interférence des descendants du 220Rn peut conduire à des résultats surestimés.

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.
