ISO 13165-2:2014 Water quality - Radium-226 - Part 2: Test method using emanometry

standard by International Organization for Standardization, 05/01/2014

Full Description

ISO 13165-2:2014 specifies the determination of radium-226 (²²⁶Ra) activity concentration in all types of water by emanometry. The method specified is suitable for the determination of the soluble, suspended, and total ²²⁶Ra activity concentration in all types of water with soluble ²²⁶Ra activity concentrations greater than 0,02 Bq l¹. In water containing high activity concentrations of ²²⁸Th, interference from ²²⁰Rn decay products can lead to overestimation of measured levels.
