​FACTS ABOUT RADON
-
Radon, a colourless and odourless gas, naturally seeps into homes through cracks and openings in the foundation, regardless of location or climate.
-
The soil beneath homes is the main source of radon gas, which can accumulate indoors due to limited ventilation, posing health risks to occupants.
-
Home radon testing kits offer a simple and affordable way to monitor indoor radon levels regularly, enabling early detection and mitigation.
-
High indoor radon levels increase the risk of lung cancer as inhaling radon particles can damage lung tissue over time.
-
Mitigation measures such as sealing cracks and installing ventilation systems help reduce radon infiltration, safeguarding indoor air quality.
