The good news about radon is that it is relatively easy to control. Research carried out by the US EPA and others has shown that it is possible to bring down the radon levels in buildings. There are a wide variety of remediation techniques available, and which one is most appropriate for a given building will depend on the amount of radon it contains and the design of the structure. Building owners should seek the advice of state-licensed mitigation contractors. A list of state-licensed mitigation contractors is provided on this site. These people can also perform the initial radon testing. However, if there is a concern about a possible conflict of interest, owners may wish to consider having the initial radon measurements, on which the decision to remediate are based, conducted by a different state-licensed company.
