Water quality - Measurement of gross beta activity in non-saline water - Thick source method

ISO 9697:2008 specifies a method for the determination of gross beta activity in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies > 0,3 MeV. Measurement of very low energy beta emitters, such as 3H; 14C, 35S and 241Pu, is not included in ISO 9697:2008.The method is applicable to the analysis of raw and potable waters.

Water quality - Measurement of gross beta activity in non-saline water - Thick source method

ISO 9697:2008 specifies a method for the determination of gross beta activity in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies > 0,3 MeV. Measurement of very low energy beta emitters, such as ³H; ¹⁴C, ³⁵S and ²⁴¹Pu, is not included in ISO 9697:2008.

The method is applicable to the analysis of raw and potable waters.

Water quality - Gross beta activity in non-saline water - Test method using thick source

ISO 9697:2015 specifies a test method for the determination of gross beta activity concentration in non-saline waters. The method covers non-volatile radionuclides with maximum beta energies of approximately 0,3 MeV or higher. Measurement of low energy beta emitters (e.g. 3H, 228Ra, 210Pb, 14C, 35S, and 241Pu) and some gaseous or volatile radionuclides (e.g. radon and radioiodine) might not be included in the gross beta quantification using the test method described in ISO 9697:2015. This test method is applicable to the analysis of raw and drinking waters. The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter used. It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.

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.
