<p style="margin:2px !important;">DUS 2089: 2018, Standard Test Method for Uranium in Drinking Water by High-Resolution Alpha-Liquid-Scintillation Spectrometry, First Edition.</p>
ICS Code
Description of Content

This draft Uganda standard specifies a test method for the determination of total soluble uranium activity in drinking water in the range of 0.037 Bq/l (1 pCi/l) or greater by selective solvent extraction and high-resolution alpha-liquid-scintillation spectrometry. The energy resolution obtainable with this technique also allows estimation of the 238U to 234U activity ratio.
