Radon is a gas that has no color, odor, or taste and comes from the natural radioactive breakdown of uranium in the ground. It can sometimes be found in your home air supply from soil. As uranium in the soil breaks down, radon gas forms and seeps into the house. Radon from soil can get into any type of building – homes, offices, and schools – and build up to high levels in the air inside the building.
Radon gas can dissolve and accumulate in water from underground sources, such as wells. When water that contains radon is used in the home for showering, washing dishes, and cooking, radon gas escapes from the water and goes into the air and can also remain in the water.
