Annotation of standard text ČSN EN ISO 11665-5 (404013):

This document describes continuous measurement methods for radon-222. It gives indications for continuous measuring of the temporal variations of radon activity concentration in open or confined atmospheres. This document is intended for assessing temporal changes in radon activity concentration in the environment, in public buildings, in homes and in work places, as a function of influence quantities such as ventilation and/or meteorological conditions. The measurement method described is applicable to air samples with radon activity concentration greater than 5 Bq/m3
