Any home, regardless of when it was built, its location, or the materials used to build the home, can expose its residents to radon. Many states require that a home’s radon history be disclosed to potential buyers. As a result, radon testing may play an important role in the real estate transaction process. Real estate agents that are better informed on the potential hazards associated with radon as well as mitigation techniques will be able to better guide their clients through the real estate transaction process.
