Measurement of radioactivity in the environment. Air: radon-222 - Continuous measurement methods of the activity concentration Ingestion-build-68772 This first amendment to Part1 Scope 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
