Although radon exposure is an established cause of lung cancer among underground miners, the lung cancer risk to the general population from indoor radon remains controversial. This controversy stems in part from the contradictory results of published studies of indoor radon and lung cancer, including 15 ecologic studies, seven of which found a positive association, six no association, and two a negative association. To address the misunderstanding of the indoor radon risk that has resulted from these ecologic studies, the authors discuss the general methodologic problems and limitations of ecologic studies, and the particular limitations of these 15 studies. The authors conclude that the shortcomings of the ecologic studies render them uninformative on the lung cancer risk associated with indoor radon.
尽管氡暴露是地下矿工患肺癌的一个既定原因，但室内氡对普通人群的肺癌风险仍存在争议。这种争议部分源于已发表的关于室内氡与肺癌研究的相互矛盾的结果，其中包括15项生态学研究，其中7项发现呈正相关，6项无关联，2项呈负相关。为了解决这些生态学研究导致的对室内氡风险的误解，作者讨论了生态学研究的一般方法学问题和局限性，以及这15项研究的特殊局限性。作者得出结论，生态学研究的缺点使其无法提供与室内氡相关的肺癌风险信息。
