When taking steps to reduce your radon levels, Health Canada recommends taking actions that will reduce your radon levels to as low as possible.
According to research the most efficient method of reducing residential radon levels is through installation of an Active Soil Depressurization (ASD) or a radon mitigation system installed by a certified professional.
Additional, but less effective, methods of radon reduction may include sealing cracks or other radon entry routes or increasing ventilation through balancing or installing an HRV (Heat Recovery Ventilator) or ERV (Energy Recovery Ventilator) system. See Health Canada’s ASD study for more information.
