Abstract

Abstract: Radon is a naturally occurring radioactive gas that enters homes through cracks in the foundation where accumulated levels can cause lung cancer. Within the United States (U.S.), state level radon reduction strategies rely on education and outreach to motivate people to test and mitigate their home. Only about 5% of the housing units in Colorado, U.S. have been tested for radon. This study looks at the 2012 Behavioral Risk Factors Surveillance System (BRFSS) in Colorado to identify distinct groups of people using Latent Class Analysis, and compares radon awareness, testing, and mitigation to understand underlying differences of radon reduction behaviors using path models. Five classes were identified: 1) Wealthy Young Families, 2) Older Singles, 3) Empty Nesters, 4) Smokers, and 5) Struggling Young Families. Significant differences in responses to radon survey questions existed across groups in which Struggling Young Families were the least likely to be aware of radon, have tested their home for radon, and have their home mitigated. Average radon awareness, testing, and mitigation appeared to be influenced by financial stress. Results from this study can be used to tailor future radon interventions and policy initiatives to enhance equity of radon reduction behaviors including legal framework to ensure radon mitigation takes place in rental properties. Highlights: Socioeconomic data was used to understand current radon knowledge and behaviors in Colorado. Low income families were the least likely to know of radon and test their homes. Financial stress, home ownership, and families impact radon awareness and testing.
