Exposure to radon and its decay products has increased as the United States has changed from an outdoor society to a largely indoor society. Radon, which is found primarily in the soil, enters houses and buildings through cracks, holes and pipes in foundation walls and floors. Although radon is suspected of being a significant cause of lung cancer, comparisons with other risk factors cannot yet be made. Radon levels in the home can be measured with commercially available kits. Guidelines for reducing the amount of radon in a home are provided by the U.S. Environmental Protection Agency.
随着美国从一个以户外活动为主的社会转变为一个主要以室内活动为主的社会，接触氡及其衰变产物的情况有所增加。氡主要存在于土壤中，通过地基墙壁和地板上的裂缝、孔洞及管道进入房屋和建筑物。尽管氡被怀疑是肺癌的一个重要病因，但目前还无法与其他风险因素进行比较。家庭中的氡水平可以使用市售的检测试剂盒进行测量。美国环境保护局提供了降低家庭中氡含量的指导方针。
