Description / Abstract:
This part of ISO 11665 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 ISO 11665 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.
