Long-term exposure to indoor radon may lead to an increased lifetime risk of lung cancer. Because millions of U.S. residential homes may have elevated radon levels, indoor radon exposure may pose a substantial public health threat. In Anne Arundel County (Maryland), a county-wide residential radon survey indicated that 82% of all residential radon readings in the survey were below Environmental Protection Agency remediation guidelines. Of the elevated indoor measurements, however, 94.4% were distributed in the southern portion of the county. These results are consistent with data compiled by the EPA and the U.S. Geologic Survey. Continued residential radon testing should be encouraged, especially in areas with elevated readings.
长期接触室内氡气可能会增加患肺癌的终生风险。由于数百万美国住宅的氡气水平可能升高，室内氡气暴露可能对公众健康构成重大威胁。在马里兰州的安妮阿伦德尔县，一项全县范围内的住宅氡气调查表明，调查中所有住宅的氡气读数有82%低于美国环境保护局的整治标准。然而，在室内测量值升高的情况中，94.4%分布在该县南部地区。这些结果与美国环境保护局和美国地质调查局汇编的数据一致。应鼓励持续进行住宅氡气检测，尤其是在读数升高的地区。
