Description

This part of ISO 13165 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 soluble²²⁶Ra 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, and²²⁸Ra, to be determined.
