Radon is present in nearly all air. Everyone breathes radon in every day, usually at very low levels. However, people who inhale high levels of radon are at an increased risk for developing lung cancer.
Radon can enter homes through cracks in floors, walls, or foundations, and collect indoors. It can also be released from building materials, or from water obtained from wells that contain radon. Radon levels can be higher in homes that are well insulated, tightly sealed, and/or built on uranium-rich soil. Because of their closeness to the ground, basement and first floors typically have the highest radon levels.
