A consideration of the effects of residential mobility produces much more realistic estimates of typical individuals' radon exposures and mortality risks than those of the Environmental Protection Agency (EPA).
A model linking residential mobility, the distribution of radon in US homes, and lung cancer risk is used to simulate lifetime radon exposure, with and without mitigation of high-radon homes, for typical mobile individuals. Radon-related lung cancer mortality risks are then estimated for smokers and never-smokers.
Most individuals residing in high-radon homes have equivalent lifelong radon exposures well below those they are currently experiencing. Consequently, actual lung cancer risks are generally well below those implied in the EPA's radon risk charts. For most people who mitigate high-radon homes, risk reduction is modest.
Radon may indeed be responsible for as large a population risk of lung cancer as the EPA estimates. However, caution must be used in interpreting the EPA's risk assessment for individuals; in many cases, mitigation will have little effect on residents' health risks.
与美国环境保护局（EPA）相比，考虑居住流动性对典型个体的氡暴露和死亡风险进行估计要现实得多。
使用一个将居住流动性、美国家庭中氡的分布以及肺癌风险联系起来的模型，来模拟典型流动个体在有或没有对高氡房屋进行缓解措施的情况下的终生氡暴露。然后估计吸烟者和从不吸烟者与氡相关的肺癌死亡风险。
大多数居住在高氡房屋中的个体终生的氡暴露量远低于他们目前所经历的水平。因此，实际的肺癌风险通常远低于EPA氡风险图表中所暗示的风险。对于大多数对高氡房屋采取缓解措施的人来说，风险降低幅度不大。
氡确实可能像EPA估计的那样，对大量人群构成肺癌风险。然而，在解释EPA对个体的风险评估时必须谨慎；在许多情况下，缓解措施对居民健康风险的影响很小。
