WARNING — Persons using this part of ISO 13165 should be familiar with normal laboratory
practice. This part of ISO 13165 does not purport to address all of the safety problems, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety and
health practices and to ensure compliance with any national regulatory conditions.
IMPORTANT — It is absolutely essential that tests conducted in accordance with this part of
ISO 13165 be carried out by suitably qualified staff.
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 soluble
226Ra 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.
