Active radon remediation

RADON REMEDIATION METHODS PASSIVE METHODS ACTIVE METHODS Barriers Natural airflow Sump systems Reduce pressure Underfloor extraction Sump systems Underfloor ventilation Cellar ventillation Positive pressure fans Raise pressure No fans or pumps

Active radon protection systems have fans. These either draw radon away from a building by lowering the air pressure under the floors (extraction) or create an area of higher air pressure that deters it (ventilation). Active methods generally have much greater impact than passive ones.

  1. Reduce the pressure (Extraction).
  2. Raise the pressure - positive pressurisation (Ventilation).
