Radon in basement is a hidden threat that seeps up from the soil through cracks in the foundation. You cannot see or smell it, but long-term exposure can harm your health. Testing is the only way to know your levels, and it's easy to do with a simple kit. If levels are high, sealing cracks and improving ventilation can help reduce it.
