Abstract
A subslab ventilation system was designed and installed in a high rado n house in Brittany, France. Radon concentration in the basement of th is house was reduced from an average 10 000 Bq/m(3) to less than 200 B q/m(3), thanks to a subslab depressurization system with a double barr ier and a 32 W fan. Sealing the concrete slab cracks greatly improved the system performance. Finally, the feasibility of using a passive do uble barrier ventilation system is shown.
