Abstract
Radon is the second leading cause of lung cancer in the United States, and is a concern for indoor air quality. Despite the widespread availability of free or low-cost tests, many people have not tested their homes for radon. This manuscript summarizes a qualitative study, conducted via focus groups and interviews with community members and professionals, to understand the barriers and facilitators that impact home radon testing. Following the Health Belief Model, the findings of this study suggest that interventions to facilitate home radon testing may benefit from a collaborative effort involving health, real estate, regulatory, and environmental sectors.
