Anyone who has bought or sold a home in recent years may already be familiar with Radon gas. Because Radon gas poses a long-term health risk, it is worth understanding its implications.

Radon is everywhere. It is a naturally occurring invisible, colorless, odorless and tasteless gas produced from the breakdown of Uranium in rock, soil, and water. It becomes a concern when that rock, soil, and/or water is under our homes because it produces low-grade radiation which gains entry into buildings through openings in foundations, collecting particularly in low lying areas of structures.  Prolonged exposure to Radon increases the risk of developing lung cancer and it is the second most prevalent cause of the disease with approximately 21,000 cases annually. Therefore, testing, removing, and preventing Radon exposure is important. 

It is estimated that one of every fifteen homes in the country, and closer to one out of every four in the Chicago Metro area, has an elevated Radon level, specifically defined as 4 pCi/L or higher. The prevalence of elevated Radon gas may vary from area to area.  So it is best to check with Radon experts in your local region for the frequency in your community.  It is recommended that homes be tested for Radon gas every two years and especially after any significant renovations. Testing may be done by individual homeowners; however, if your home will be listed for sale, more stringent requirements regarding testing may be applicable.  Check your state’s rules and regulations with regards to testing and for information about Radon as listed on the EPA site

Fortunately, reducing Radon gas levels is fairly simple and relatively inexpensive. Today many new homes are designed with prevention in mind and built with technology that eliminates most of the concern. Your real estate agent should be able to provide information regarding Radon testing, removal and prevention.

Most homeowners’ questions regarding testing, removal and prevention of Radon gas in our homes can be found on the EPA website where abundant information for home sellers, homebuyers and homeowners is readily available.  For recommendations regarding Radon testing and Radon mitigation services in Chicago’s North Shore, North and Northwest suburbs, feel free to contact me today.  I will be happy to answer any questions you may have, help you to find a new home or determine the value of your existing property.
