标准范围

This part of ISO 13165 specifies the determination of radium-226 (226Ra) activity concentration in alltypes of water by coprecipitation followed by gamma-spectrometry (see ISO 18589?3).The method described is suitable for determination of soluble 226Ra activity concentrations greaterthan 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 followingISO 10703 with a higher detection limit.NOTE This test method also allows other isotopes of radium, 223Ra, 224Ra, and 228Ra, to be determined.
