A radon alarm sits quietly in the basement, its small display glowing green when air levels are safe. If the radioactive gas seeps up from the soil, the device chirps a warning, prompting you to ventilate or call a professional. It is not a gadget for show, but a silent guardian that might save your lungs from long-term damage.
