Rural parents' perceptions of risks associated with their children's exposure to radon.

OBJECTIVES To examine the level of awareness of radon issues, correlates of elective testing behaviors, and the accuracy of risk perception for radon exposures among rural residents receiving public health services. DESIGN A cross-sectional design was used in which questionnaire data and household analytic data for radon levels were collected from a nonprobabilistic sample of rural households. SAMPLE Thirty-one rural households with 71 adults and 60 children participated in the study. Primary household respondents were female (100%), Caucasian (97%), and primarily (94%) between 21 and 40 years of age. MEASUREMENT Questionnaire data consisted of knowledge and risk perception items about radon and all homes were tested for the presence of radon. RESULTS The prevalence of high airborne radon (defined as> or=4 pCi/l) was 32%. More than a third of the sample underestimated the seriousness of health effects of radon exposure, 39% disagreed that being around less radon would improve the long-term health of their children, and 52% were unsure whether radon could cause health problems. After adjusting for chance, only 21% of the subjects correctly understood their risk status. CONCLUSIONS This study provides preliminary evidence that low-income rural citizens do not understand their risk of radon exposure or the deleterious consequences of exposure.
