Description
The exchange of air between the indoor and outdoor atmosphere is a key physical process that affects, among other things, the behaviour of all types of aerosols and gaseous contaminants, including radon/ thoron and their decay products in buildings, and mediates their transfer from indoor to outdoor air and vice versa. Commonly used technique of tracer gases was implemented into SURO’s measurement procedures in two modes, continuous and integral.
The integral air exchange rate measurement is more practical from the point of view of longer measurement time (i.e. improved coverage of user conditions), better comfort of the inhabitants of the building and tracer gas consumption. SURO utilizes integral air exchange rate measurement to objectify the results of radon measurement with respect to the minimum required hygienic air exchange rate (0.3 1/h), and as a radon diagnostic tool.
Practical use of integral air exchange measurement will be demonstrated through case studies.
