Radon is an odorless radioactive gas which is formed by the natural breakdown of uranium. Radon can be found in high concentrations in soils and rock formations containing granite, shale, phosphate and uranium in almost any area. As it is produced, it seeps up into houses through cracks and gaps in a foundation or slab.  It can also be introduced into the air through the water supply, particularly from well systems.

Considerations
Research has shown that once trapped inside a closed structure, radon can accumulate to the point where a potential health hazard may exist. The HouseMaster Technical Staff recommends that houses in recognized radon areas be screened for the presence of radon at elevated levels. High radon levels can usually be addressed for a reasonable fee in the thousand-dollar range, by installing a radon mitigation system. Newer homes in high radon areas may have radon mitigation components pre-installed for subsequent use should future problems arise.
