This part of ISO13164 describes a test method for the determination of radon-222 (222Rn) activity concentration in non-saline waters by extraction and liquid scintillation counting.
The radon-222 activity concentrations, which can be measured by this test method utilizing currently available instruments, are at least above0,5Bq l−1 for a10ml test sample and a measuring time of1h.
This test method can be used successfully with drinking water samples and it is the responsibility of the laboratory to ensure the validity of this test method for water samples of untested matrices.
AnnexA gives indication on the necessary counting conditions to meet the required detection limits for drinking water monitoring.
