Organization: CEN
Publication Date: 1 July 2023
Status: active
Page Count: 26
ICS Code (Examination of physical properties of water): 13.060.60
ICS Code (Radiation protection): 13.280
ICS Code (Radiation measurements): 17.240
scope:

This document describes a test method for the determination of radon-222 (222Rn) activity concentration in non-saline waters by extraction and liquid scintillation counting.

The 222Rn activity concentrations, which can be measured by this test method utilizing currently available instruments, are above 0,5 Bq·l−1 which is the typical detection limit for a 10 ml test sample and a measuring time of 1 h.

It is the responsibility of the laboratory to ensure the validity of this test method for water samples of untested matrices.

Annex A gives indication on the necessary counting conditions to meet the required detection limits for drinking water monitoring.
