Radon is a naturally occurring radioactive gas that can seep into basements through cracks and gaps in foundations, posing serious long-term health risks like lung cancer. Testing for radon is simple and cheap with DIY kits, and if levels are high (above 4 pCi/L), mitigation systems—like sub-slab depressurization—can effectively reduce exposure. It’s not something to panic about, but ignoring it is risky, especially if you spend a lot of time in your basement.
