Radon testing may occur in which type of homes?

Radon testing is applicable to both occupied and non-occupied homes because radon can accumulate in any enclosed space, regardless of occupancy. The presence of people does not affect the ability of radon to enter and concentrate within a building, as radon is a naturally occurring gas that can seep in through cracks in floors, walls, and other openings.

Testing can provide important information about the radon levels in various living conditions and help determine if mitigation efforts are necessary. Homes under construction can also be tested, as understanding radon levels can guide builders in incorporating loss of radon entry systems early on. Existing homes, regardless of their occupancy status, may have varying levels of radon that need to be monitored and addressed to ensure a safe living environment.
