DESCRIPTION

BS EN ISO 13164-4:2023

This standard BS EN ISO 13164-4:2023 Water quality. Radon-222 is classified in these ICS categories:

13.060.60 Examination of physical properties of water
17.240 Radiation measurements
13.280 Radiation protection

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.
