Epidemiologic investigations of underground miners and studies of alpha particle carcinogenesis among laboratory animals suggest that exposure to the radioactive decay products (progeny) of radon is an important risk factor for lung cancer. Persons who smoke cigarettes and are exposed to these radon progeny have a substantially greater risk for developing malignancy than nonsmokers. Residential radon concentrations above the U.S. Environmental Protection Agency's (EPA) action level of 4 pCi/L are the primary sources of exposure among the general population. EPA and the Public Health Service promote home testing for radon, especially in households with a person who smokes. However, it is unknown whether households that contain smokers are more likely than those without smokers to test for radon. To characterize radon testing practices of households that contain a person who smokes within the dwelling (i.e., residential smoker), CDC analyzed survey data from the National Health Interview Survey (NHIS). This report summarizes the results of this analysis, which indicates that households with a residential smoker are significantly less likely to test for radon than those without smokers.
对地下矿工的流行病学调查以及对实验动物中α粒子致癌作用的研究表明，接触氡的放射性衰变产物（子体）是肺癌的一个重要危险因素。吸烟且接触这些氡子体的人患恶性肿瘤的风险比不吸烟者要高得多。美国环境保护局（EPA）设定的行动水平为4皮居里/升，高于此水平的住宅氡浓度是普通人群接触氡的主要来源。EPA和公共卫生服务部门提倡对家庭进行氡检测，尤其是有吸烟者的家庭。然而，尚不清楚有吸烟者的家庭是否比没有吸烟者的家庭更有可能检测氡。为了描述居住环境中有吸烟者（即住宅吸烟者）的家庭的氡检测情况，美国疾病控制与预防中心（CDC）分析了来自国家健康访谈调查（NHIS）的调查数据。本报告总结了这一分析结果，结果表明，有住宅吸烟者的家庭检测氡的可能性明显低于没有吸烟者的家庭。
