US radon research, policy and programs have stalled since their start in the late 1980s and early 1990s. In 2005, more homes had radon above the US Environmental Protection Agency (EPA) Reference Level than anytime in history since more homes were added to the housing stock that had indoor radon concentrations exceeding 150 Bq m(-3) than had been mitigated. Funding for the US radon program has declined two-thirds from 1997 to 2007. Despite impressive goals for radon reduction, EPA lacks sound progress indicators especially in new construction radon control systems. School radon reduction has been at a standstill since the early 1990s. There has been no significant radon risk reduction in low-income sectors of the population. There is need for effective partnerships between the public and private sectors of the US radon professional communities as well as with the international programs and professionals.
自20世纪80年代末和90年代初启动以来，美国的氡研究、政策及项目陷入停滞。2005年，氡含量超过美国环境保护局（EPA）参考水平的家庭数量比历史上任何时候都多，因为新增住房存量中室内氡浓度超过150贝克勒尔每立方米的房屋数量多于已得到缓解的数量。从1997年到2007年，美国氡项目的资金减少了三分之二。尽管在降低氡含量方面设定了令人瞩目的目标，但EPA缺乏完善的进展指标，尤其是在新建建筑的氡控制系统方面。自20世纪90年代初以来，学校降低氡含量的工作一直停滞不前。低收入人群中的氡风险没有显著降低。美国氡专业领域的公共和私营部门之间以及与国际项目和专业人员之间需要建立有效的伙伴关系。
