Radon in basement is a serious concern because this radioactive gas seeps up from the soil through foundation cracks and can accumulate to dangerous levels. Since basements are often poorly ventilated, radon concentrations can climb much higher there than upstairs. Testing for radon is the only way to know if your home is affected, and if levels are high, mitigation systems can vent the gas outside. It's not something to panic over, but it's worth keeping an eye on for your family's health.
