Water quality - Uranium isotopes - Test method using alpha-spectrometry

This document specifies the conditions for the determination of uranium isotope activity concentration in samples of environmental water (including sea waters) using alpha-spectrometry and 232U as a yield tracer. A chemical separation is required to separate and purify uranium from a test portion of the sample.

Water quality - Uranium isotopes - Test method using alpha-spectrometry

<p>ISO 13166:2014 specifies the conditions for the determination of uranium isotope activity concentration in samples of environmental water (including sea waters) using alpha-spectrometry and <sup>232</sup>U as a yield tracer. A chemical separation is required to separate and purify uranium from a test portion of the sample.</p> <p>Plutonium isotopes can interfere, if present, with detectable activities in the sample.</p> <p>The detection limit for measurement of a test portion of about 500 ml is approximately 5 mBq · l<sup>−1</sup> with a counting time of about 200 000 s.</p>

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.
