Radon is the leading cause of lung cancer after smoking, killing 7,000-30,000 people annually. The combination of radon exposure and smoking produces a synergy that markedly raises the risk of mortality. For smokers exposure to low to moderate levels of radon, changing smoking behavior is the most efficient risk reduction strategy. The aim of this randomized trial is to test interventions for households where a smoker is present and there are detectable levels of radon. This competing renewal extends ongoing work, which demonstrated that utility, which demonstrated that utility company bill stuffers were an effective recruitment device and found that brief phone counseling produced short-term (3- month follow-up) changes across several outcome measures. This 4-year project will work with a new electric utility in a region with higher levels of radon. Smoking households that return bill stuffer coupons will be randomized to 1 of 4 conditions in a 2 X 2 factorial design: phone counseling versus no counseling by, video/CD-ROM versus no video/CD-ROM. Control households will receive standard EPA written materials on radon and smoking. All households receive feedback on their radon level. Telephone counseling is hypothesized to produce significant changes in smoking comparable to those found in our current study. The visual and potentially interactive displays possible in the video/CD-ROM are expected to produce changes comparable to the phone counseling. The combination condition is expected to be significantly better than either alone. Follow up assessments will be conducted by mail and phone. Sustained quitting of smoking at both 3 and 12 months and changes in household smoking rules are primarily outcome measures. Adjunctively, we will examine participants' mental models of radon smoking risk using revised measures and conducting subanalyses on high radon households. The interventions are potentially disseminable at low cost and, collaboratively with utility companies, could motivate large numbers of households to test for radon and take appropriate risk reduction strategies.

氡是吸烟后导致肺癌的主要原因，每年导致7000-3万人死亡。氡暴露和吸烟的结合产生了显著增加死亡风险的协同效应。对于暴露在低到中等水平的氡的吸烟者来说，改变吸烟行为是最有效的降低风险的策略。这项随机试验的目的是测试对有吸烟者和可检测到氡水平的家庭的干预措施。这一竞争性续签延长了正在进行的工作，该工作证明了公用事业公司的账单填充物是一种有效的招聘手段，并发现短暂的电话咨询在几个结果指标上产生了短期(3个月随访)的变化。这个为期4年的项目将与一个氡水平较高的地区的一家新的电力公司合作。退还填充券的吸烟家庭将在2×2析因设计中随机分为4种情况之一：电话咨询与不咨询、视频/CD-ROM与不视频/CD-ROM。对照家庭将收到美国环保局关于氡和吸烟的标准书面材料。所有家庭都会收到关于他们的氡水平的反馈。据推测，电话咨询会产生与我们目前研究中发现的类似的吸烟显著变化。视频/CD-ROM中可能出现的可视和潜在的交互式显示预计将产生与电话咨询相当的变化。预计合并后的情况将明显好于其中任何一项。后续评估将通过邮件和电话进行。在3个月和12个月内持续戒烟和改变家庭吸烟规则主要是结果衡量标准。此外，我们将使用修订后的测量方法和对高氡家庭进行细分分析，来检查参与者对氡吸烟风险的心理模型。这些干预措施有可能以低成本传播，并与公用事业公司合作，可以激励大量家庭进行氡测试并采取适当的减少风险战略。
