There are so many misconceptions about radon, especially where it's likely to be in a home. Many buyers ask if a radon test is necessary if there is no basement in a home. Yes, it is. Some clients may have seen this Portland map which may lead them to think they are not in a hot area and therefore that a test may not be necessary. Yes, it is.
Fact: radon is the second leading cause of lung cancer in the U.S. Fact: radon can be in any neighborhood, one home can have it while their neighbor may not. Fact: tests have become easier, more reliable and mitigating radon is relatively simple.
