Water quality. Radon-222 - Test method using gamma-ray spectrometry1 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

l) The stability requirements and dimensional limitations accord with BS 8103-1:1995+Amendment 1:1995

This method can also be applied to other solid samples such as sediments and solid wastes

- industrial installations and power plants

c) Installations in hazardous areas (these are defined in The Dangerous Substances and Explosive Atmospheres Regulations)

Explosion isolation shall also be ensured during periods without process flow
