Water quality - Radium 226 - Part 1 : test method using liquid scintillation counting

ISO 13165-1:2013 specifies the determination of radium-226 (226Ra) activity concentration in non-saline water samples by extraction of its daughter radon-222 (222Rn) and its measurement using liquid scintillation counting.Radium-226 activity concentrations which can be measured by this test method utilizing currently available liquid scintillation counters goes down to 50 mBq l−1. This method is not applicable to the measurement of other radium isotopes.

Nuclear energy - Measurement of radioactivity in the environment - Water - Part 3 : measurement of radium 226 activity in water - Method by liquid scintillation

Le présent document expose les principes et les difficultés de la détermination de l'activité du radium 226, dans tous types d'eaux par scintillation liquide alpha. La méthode est applicable à tous les types d'eaux d'activités en 226Ra soluble supérieures à 0,04 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.

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