European Indoor Radon Maps 2024
Epidemiological studies and extensive research have established a strong consensus among national and international health organizations that chronic exposure to elevated radon concentrations significantly increases the risk of lung cancer. Enclosed environments, i.e. areas with low to no continuous ventilation, are more prone to radon accumulation over time. The European Union Member States, as well as other neighbouring countries, have recently carried out radon surveys within their national radon action plans that are fundamental to ensure that radon concentrations are kept below the national reference levels.
The European Commission Joint Research Centre has collected the readings carried out on the ground floors of residential buildings and made them publicly available as geographical maps showing the number of measurements and average concentration at a 10-km side square geographical cell. These maps—called the European Indoor Radon Maps (EIRM)—have been periodically published online since 2018. The current report includes the latest updated EIRMs, published in November 2024, along with additional information related to this update. The work was carried out under the coordination of the European Commission Joint Research Centre (EC-JRC) within the REMON project framework in line with the science for policy mandate of the JRC.
