Water quality - Radon-222 - Part 2: Test method using gamma-ray spectrometry
Abstract
This part of ISO 13164 specifies a test method for the determination of 222Rn activity concentration in a sample of water by the measurement of its short-lived decay products by direct gamma-spectrometry of a water sample (see Annex A). The 222Rn 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 thousand becquerels per litre for a 1 l test sample. This test method can be used successfully with drinking water samples. The laboratory is responsible for ensuring the validity of this test method for water samples of untested matrices. Annex B gives indication on the necessary counting conditions to meet the required sensitivity for drinking water monitoring.
