氡是室内主要的空气污染物，对那些暴露在家中的人群构成显著的肺癌风险。虽然已经证明在家中降低高氡水平可以有效减少这种风险，但家庭氡处理率仍然很低。本研究从负责氡风险管理的官方机构、氡处理行业（承包商）和四个高氡风险和低处理率的欧洲国家（比利时、爱尔兰、斯洛文尼亚和英国）的居民的角度，研究了家庭氡处理的障碍和促进因素。采用多种方法，包括在线调查、法律文件内容分析、小组访谈、研讨会和焦点小组，收集了各方利益相关者的数据。官方机构、承包商和居民识别出氡处理的各种促进因素，包括处理的法律要求、宣传活动、处理费用低、财政支持的可获得性、处理承包商的认证和对氡视为健康威胁的感知。然而，还确定了处理的障碍，例如缺乏意识、碎片化的处理过程和利益相关者之间的不充分沟通。本研究强调了氡处理过程的复杂性，并提出应针对除居民外的利益相关者，如建筑商、卫生专业人员和决策者，实施旨在提高处理率的干预措施。从政策到供应的整合方法是降低这种室内空气污染物水平的有效途径。版权所有 © 2023 Hevey、Perko、Martell、Bradley、Apers和Rovenská。

Radon is a major indoor air pollutant that poses a significant risk of lung cancer to those exposed in their homes. While mitigation of high radon levels in homes has been shown to be effective, home mitigation rates remain low. This study examines the barriers and facilitators to radon mitigation in homes from the perspectives of authorities responsible for radon risk management, the mitigation industry (contractors), and residents in four European countries (Belgium, Ireland, Slovenia, and the UK) with high radon risks and low mitigation rates.A multi-method approach was used to gather data from various stakeholders, including online surveys, content analysis of legal documents, group interviews, workshops, and focus groups.Authorities, contractors, and residents identified various facilitators to radon mitigation, including legal requirements for mitigation, awareness campaigns, low mitigation costs, availability of financial support, accreditation of mitigation contractors, and a perception of radon as a health threat. However, barriers to mitigation were also identified, such as a lack of awareness, fragmented mitigation processes, and inadequate communication between stakeholders.The study highlights the complexity of the radon mitigation process and suggests that interventions aimed at increasing mitigation rates should target stakeholders beyond just residents, such as constructors, health professionals, and policy makers. An integrated approach to radon mitigation, from policy to provision, is necessary to effectively lower levels of this indoor air pollutant.Copyright © 2023 Hevey, Perko, Martell, Bradley, Apers and Rovenská.
