The NS Department of Health and Wellness recommends that all home owners in the province test their homes for radon. In 2013 the Nova Scotia Department of Natural Resources released a “Map Showing Potential for Radon in Indoor Air“. This comprehensive map is useful for determining priority areas for testing. Some areas of the province have a higher risk of radon because of local bedrock geology and soil permeability. It should be noted, however, that even low radon potential areas will contain homes with high radon levels and there are no areas completely devoid of homes with high radon. No matter where you live, the only way to know for sure whether your home has high radon levels is to test.
