摘　　要：氡是一种自然发生的放射活性气体。U系(238U)放射性衰变时所释放的氡气广泛存在于室内和室外空气中。大量的地下矿场和动物实验流行病学研究证实在吸烟和非吸烟人群中氡可诱发肺癌。因此,从泥土、水和建筑材料释放到室内空气中的氡已被认为是一种诱发肺癌的潜在性重要因素。本文献综述对氡的来源,室内氡的水平,流行病学研究,室内氡污染原理以及室内氡与肺癌发生的关系进行综述。Radon is a naturally occurring radioactive gas. Radon gas released during the decay of uranium-238, is ubiquitous in indoor and outdoor air. Extensive epidemiologic evidence from studies of underground ininers and Complementary animal data have documented that radon causes lung cancer in smokers and nonsmokers. Radon has also been Considered a potentially important cause of lung cancer for the general population, which is exposed through contamination of indoor air by radon from soil, water, and building materials. This review describes radon＇s sources, levels in homes, the epidemiologic evidence studies, the principal of radon pollution and the relationship between residential radon gas exposure and lung cancer.
