Water quality - Determination of the activity concentration of radionuclides - Method by high resolution gamma-ray spectrometry

ISO 10703:2007 specifies a method for the simultaneous determination of the activity concentration of various radionuclides emitting gamma rays with energies between 40 keV and 2 MeV in water samples, by gamma‑ray spectrometry using germanium detectors with high energy resolution in combination with a multichannel analyser.

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!
