ISO 13165:2024 Water quality – Radium-226 – Part 3: Test method using coprecipitation and gamma-ray spectrometry
CDN $173.00
Description
This document specifies a method to determine radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-ray spectrometry (see ISO 20042[7]).
The method covers the measurement of soluble 226Ra activity concentrations greater than 0,002 Bq·l−1 using a sample volume of up to 100 l of any water type.
For water samples with a volume of less than a volume of 1 l, direct gamma-ray spectrometry can be performed following ISO 10703 but with a higher detection limit. The typical detection limit for samples of 1 l to 5 l is in the range of 0,002 to 0,000 40 Bq·l−1[8].
NOTE            This test method can be adapted to determine other naturally occurring isotopes of radium, such as 223Ra, 224Ra and 228Ra, if the respective ingrowth periods are taken into account.
