On the basis of recent epidemiological findings, many international and national organisations have revised their recommendations and regulations on radon exposure in dwellings and workplaces, or are in the process to do it. In particular, new recommendations and regulations were recently published (or are going to be) by World Health Organization, Nordic Countries, International Commission on Radiological Protection, International, Atomic Energy Agency (and the other international organisations sponsoring the International Basic Safety Standards), European Commission. Although with some differences, these new documents recommend lower radon concentrations in indoor air, especially in dwellings, compared with previous ones. Moreover, preventive measures in all new buildings are more and more considered as one of the most cost-effective way to reduce the radon-related lung cancers, compared with previous approach restricting preventive measures in radon-prone areas only. A comprehensive national action plan, involving several national and local authorities, is generally considered a necessary tool to deal with the many complex actions needed to reduce the risk from radon exposure in an effective way.
基于近期的流行病学研究结果，许多国际和国家组织已修订了其关于住宅和工作场所氡暴露的建议和规定，或者正在进行修订。特别是，世界卫生组织、北欧国家、国际放射防护委员会、国际原子能机构（以及赞助《国际基本安全标准》的其他国际组织）、欧盟委员会最近（或即将）发布了新的建议和规定。尽管存在一些差异，但与之前的文件相比，这些新文件建议室内空气中的氡浓度更低，尤其是在住宅中。此外，与之前仅在氡易发地区限制预防措施的方法相比，现在越来越多地认为在所有新建筑中采取预防措施是降低与氡相关肺癌的最具成本效益的方法之一。一般认为，一项涉及多个国家和地方当局的全面国家行动计划是有效应对降低氡暴露风险所需的众多复杂行动的必要工具。
