Scope

This standard describes a method for the measurement of Zirconium-93 in water samples using inductively coupled plasma mass spectrometry (ICP-MS).

The method describes direct measurement of water samples without prior separation, as well as radiochemical separation using extraction chromatography, depending on the water sample analysed and ICP-MS design.

Purpose

Zirconium-93 is a man-made radionuclide, with enhanced concentrations in water samples due to certain human activities.

Enhanced activity concentrations of Zirconium-93 in drinking water presents a potential risk to human health. It is therefore important to monitor the Zirconium-93 content as part of the assessment of drinking water quality, in order to comply with international and national authority regulations. An International Standard on a test method for Zirconium-93 concentration in water samples is justified for test laboratories carrying out these measurements, required sometimes by national authorities, as laboratories may have to obtain a specific accreditation for radionuclide measurement in drinking water samples
