Water quality. Radon-222 - General principles Ingestion-build-260237 which indicates density in grams1 Scope This part of ISO 13164 gives general guidelines for sampling, packaging, and transporting of all kinds of water samples, 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 any transfer of phase (see ISO 131642); b) indirect measurement involving the transfer of the radon 222 from the aqueous phase to another phase (see ISO 131643).
