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 than0,002Bq·l?1 using a sample volume of up to 100l of any water type. For water samples with a volume of less than a volume of 1l, direct gamma-ray spectrometry can be performed following ISO 10703 but with a higher detection limit. The typical detection limit for samples of 1l to 5l is in the range of 0,002 to 0,00040Bq·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.
