Measurement of radioactivity in the environment -Air: radon-222 - Part 5: Continuous measurement method of the activity concentration (ISO 11665-5:2012)
ISO 11665-5:2012 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.ISO 11665-5:2012 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.
