Radon Detection and Reduction questions, answered by experts

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

Since radon typically comes out of the soil, it is most commonly found in the lower levels of a home. In houses with basements, that's a common location for radon. Homes built directly on the ground may have radon on the ground floors. Radon can be found on the upper floors of the home, but often in lower concentrations than in lower levels.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Testing typically costs between $150 and $500, depending on the method used and the number of areas tested.
