Radon in basement is a serious concern because this radioactive gas can seep through cracks in the foundation from the soil, accumulating to dangerous levels. Since basements are often poorly ventilated, the risk is higher. Testing is the only way to know if you have a problem, and if levels are elevated, mitigation steps like sealing cracks or installing a vent system can reduce exposure and protect your long-term health.
