Water quality. Radon-222 - Test method using gamma-ray spectrometry Ingestion-build-224916 groups of items1 Scope This part of ISO 13164 specifies a test method for the determination of radon 222 activity concentration in a sample of water following the measurement of its short lived decay products by direct gamma spectrometry of the water sample (see Annex A). The radon 222 activity concentrations, which can be measured by this test method utilizing currently available gamma ray instruments, range from a few becquerels per litre to several hundred
