The following represents our opinion, based on our understanding of the radon issue from several sources. However, we recommend retesting the radon levels once you move in, to verify this low reading. The selling agent ordered a retest by a tester known to test on the second floor with the windows open. Although he never gave my clients a written report stating this. Cigarette smokers should keep their exposure to radon as low as possible.
Smokers have eight times the risk from radon as non smokers.
If the house was tested in an infrequently used basement. It may have measured a radon level that is two to three times the actual level you are exposed to, spending most of your time upstairs. This may be appropriate for slightly elevated houses that don't need year round reductions. People with young children should be more concerned with the possible consequences of radon exposure 20 years from now than someone in their late sixties or seventies. Families with a hereditary predisposition of cancer should be more concerned about radon exposure than families who don't have any history of cancer.
