To create awareness of the dangers of radon gas and to provide family physicians with updated, practical information to help educate patients.
MEDLINE (1950 to February 2013), the Cochrane Database of Systematic Reviews (2005 to 2013), and the Cochrane Central Register of Controlled Trials (2005 to 2013) were searched using relevant terms. Guidelines, position statements, articles, and original research relevant to radon were selected.
Radon is the principal cause of lung cancer in non-smokers and the second most common cause in smokers (1 in 20 and 1 in 3, respectively), and lifetime risk increases in a linear fashion with radon exposure. In outdoor air, radon is diluted and is not a health concern, but as it diffuses into houses, the gas accumulates, reaching high concentrations, and becomes a health hazard. The Canadian guideline for the maximum acceptable concentration for indoor air is 200 Bq/m, and there are cost-effective methods available to reduce radon gas when high levels are found in dwellings.
Family physicians play a fundamental role in the prevention of radon-related lung cancer by educating their patients, guiding them about specific preventive actions, and advocating on patients' behalf.
提高人们对氡气危害的认识，并为家庭医生提供最新、实用的信息，帮助教育患者。
使用相关术语在 MEDLINE（1950 年至 2013 年 2 月）、Cochrane 系统评价数据库（2005 年至 2013 年）和 Cochrane 对照试验中央登记处（2005 年至 2013 年）进行检索。选择了与氡相关的指南、立场声明、文章和原始研究。
氡是不吸烟者肺癌的主要病因，在吸烟者中是第二大常见病因（分别为 1/20 和 1/3），且终生风险随氡暴露呈线性增加。在室外空气中，氡被稀释，不会对健康造成危害，但当它扩散到房屋中时，气体积聚，浓度达到很高水平，就会成为健康危害。加拿大室内空气最大可接受浓度的指南为 200 Bq/m，并且当住宅中氡气含量较高时，有经济有效的方法可以降低氡气。
家庭医生通过教育患者、指导他们采取具体的预防措施以及代表患者倡导，在预防与氡相关的肺癌方面发挥着重要作用。
