Water quality - Radium-226 - Part 3 : test method using coprecipitation and gamma-spectrometry

ISO 13165-3:2016 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-spectrometry (see ISO 18589‑3).The method described is suitable for determination of soluble 226Ra activity concentrations greater than 0,02 Bq l−1 using a sample volume of 1 l to 100 l of any water type.For water samples smaller than a volume of 1 l, direct gamma-spectrometry can be performed following ISO 10703 with a higher detection limit.NOTE This test method also allows other isotopes of radium, 223Ra, 224Ra, and 228Ra, to be determined.

Water quality - Radium-226 - Part 3 : test method using coprecipitation and gamma-spectrometry

ISO 13165-3:2016 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-spectrometry (see ISO 18589‑3).

The method described is suitable for determination of soluble 226Ra activity concentrations greater than 0,02 Bq l−1 using a sample volume of 1 l to 100 l of any water type.

For water samples smaller than a volume of 1 l, direct gamma-spectrometry can be performed following ISO 10703 with a higher detection limit.

NOTE This test method also allows other isotopes of radium, 223Ra, 224Ra, and 228Ra, to be determined.

Le présent document expose les principes et les difficultés de la détermination de l'activité du radium 226, dans tous types d'eaux par spectrométrie gamma. La méthode est applicable à tous les types d'eaux d'activités en 226Ra soluble supérieures à 0,02 Bq.L-1. Cette méthode permet en outre de mesurer les autres isotopes naturels en radium (radium 223, radium 224 et radium 228) .

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.
