Bibliography

Explains continuous measurement methods for radon-222. Also gives indications for continuous measuring of the temporal variations of radon activity concentration in open or confined atmospheres.

This part of ISO11665 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 part of ISO11665 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 5Bq/m 3.
