DESCRIPTION
BS EN ISO 11665-5:2020
This standard BS EN ISO 11665-5:2020 Measurement of radioactivity in the environment. Air: radon-222 is classified in these ICS categories:
- 17.240 Radiation measurements
- 13.040.01 Air quality in general
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.
