Abstract
One in three homes in Utah (USA) contains dangerous levels of radon. Except for a radon mitigation certification law, Utah’s radon laws are nonexistent. To determine public perception of state policies on radon testing and mitigation, a social cognitive theory-based 52-item questionnaire was administered to residents (N = 307) who visited the Utah County Health Department (UCHD) during the study period. Respondents were divided into an Environmental Health Group (n = 110), who purchased a radon kit, and Vital Records Control Group (n = 197), who filed/obtained birth/death certificates at UCHD. Ninety percent responded they had never tested their homes for radon, and 99% were not aware of state policies regarding radon. Support for various radon policies was significantly associated with older age (odds ratios (OR): 0.37–0.52), being female (OR: 2.60–7.79), lower annual family income (OR: 2.27), and theoretical constructs of behavioral modeling (OR: 2.31–2.55) and risk perception (OR: 2.55–3.71). To increase awareness, testing, and remediation, respondents suggested increasing public education/awareness, requiring testing in homes, businesses, and public buildings, and increasing access to testing. Multi-sectoral radon risk reduction programs could incorporate behavioral modeling and risk perception as components to create a radon testing and mitigation culture in Utah.
