Radon levels tend to rise during the winter months, and several factors contribute to this phenomenon:
Tight home sealing for warmth reduces ventilation, allowing indoor pollutants like radon to accumulate.
Warm air rising in buildings creates negative pressure, drawing in radon from the ground.
Winter freezes the ground, hindering radon's escape and increasing its concentration beneath buildings.
Some heating systems create negative pressure, pulling in radon; inefficient systems can worsen this effect.
Closed windows and doors during winter limit ventilation, leading to higher indoor radon levels.
Radon, a naturally occurring gas, poses health risks, including an increased risk of lung cancer. Testing and mitigation are crucial for a healthy indoor environment.
