Water quality — Uranium — Test method using alpha liquid scintillation counting
Product Details
This method covers the measurement of soluble uranium isotopes in water in activity concentrations between approximately 2·10-3 Bq/kg and 10 Bq/kg when analysing a 1 l test sample volume with a 60 000 s counting time with a typical alpha LSC instrument.
The ratio 234U/238U can also be determined. This method has not been tested for the measurement of other uranium isotopes.
