Testing the Properties of Radon Barrier Materials and Home Ventilation to Mitigate Indoor Radon

Indoor radon is the second cause of lung cancer. Mitigation strategies are based on (i) building protection with barrier materials, (ii) increasing home ventilation or (iii) room pressurization. A scale model created a porous ignimbrite rich in precursors was used as an analogue to test indoor reduction ability various materials real room. The properties these were tested and without pressurization by introducing outdoor air at different flow rates. best reduced up 80% and, when highest applied, 93%.
