Water quality - Simultaneous determination of tritium and carbon 14 activities - Test method using liquid scintillation counting - First Edition
N 13168
Annotation
This International Standard describes a test method for the simultaneous measurement of tritium and carbon-14 in water samples by liquid scintillation counting of a source obtained by mixing the water sample with a hydrophilic scintillation cocktail.
This is considered a screening method because of the potential presence of interfering nuclides in the test sample.
The method can be used for any type of environmental study or monitoring.
This International Standard is applicable to all types of waters having an activity concentration ranging from 5 Bq/l to 106 Bq/l (upper limit of the liquid scintillation counters for direct counting). For higher activity concentrations, the sample can be diluted to obtain a test sample within this range.
