Water quality - Radon-222. Pt. 1: General principles (ISO 13164-1:2013, Corrected version 2013-11-15); German version EN ISO 13164-1:2020

ISO 13164-1:2013 gives general guidance for the sampling, packaging and transport of water samples of all types, for the measurement of the activity concentration of radon-222. The test methods fall into two categories: a) direct measurement of the water sample without phase transfer (see ISO 13164-2); b) indirect measurement with the transfer of radon-222 from the aqueous phase to another phase (see ISO 13164-3). The test methods can be applied either in the laboratory or on site. The laboratory is responsible for ensuring the suitability of the test method for the water samples tested. This document has been prepared by Technical Committee ISO/TC 147 "Water quality" in cooperation with Technical Committee CEN/TC 230 "Water analysis". The responsible German standardisation body is the subcommittee NA 119-01-03-08 UA "Radioactivity measurement in water" of the working committee NA 119-01-03 AA "Water analysis" in the DIN Standards Committee for Water (NAW).
