Research

The Radon competence centre operates in the field of research, working closely with the HES-SO in Freiburg and the FHNW in Muttenz, along with other local, regional, national and international partners and academic institutions.

The services provide the necessary knowledge for the development of applied research projects aimed at improving prevention and remediation techniques.

Efficiency of radon remediation

The project, managed by SUPSI's Radon competence centre with important national and regional partners, had two main objectives. On the one hand, it gathered previously unknown information on radon mitigations carried out nationwide. On the other, it verified the effectiveness of the mitigation measures years after their implementation, identifying any critical issues and proposing solutions. This approach made it possible to assess the durability and efficiency of the measures taken over time, helping to improve radon management in buildings and ensuring greater protection for public health.

Air quality in school buildings

The Radon competence centre has developed an Interreg project to improve air quality (IAQ) in school buildings. The aim is to address poor air quality that affects students' health and learning. It involves cross-border companies such as ventilation installers, window and door fitters, companies and manufacturers of indoor materials, with measurements and guidelines for managing IAQ.

Radon and energy remediation

Indoor radon concentrations are strongly influenced by air flow with the outside. Non-stagnant doors and windows promote greater air exchange, while reductions in flow can significantly increase radon. This dynamic is particularly relevant in energy refurbishments that reduce the permeability of the envelope and, consequently, air exchange. In the context of the project, the effectiveness of various energy refurbishments on radon in about 200 buildings was evaluated. Measurements were carried out before and after the works, examining different intervention methods.

Technical Data Sheets

Following the revision of the Radiation Protection Ordinance on 1 January 2028, many buildings still require renovation. According to the federal database, several thousand exceed the radon reference level. New buildings must also comply with FOPH regulations. The project contributes to the 2021-2030 Radon Action Plan by improving protection in existing and new buildings and expanding professional knowledge. Fact sheets will be developed for various remediation and prevention measures, useful for professionals and owners. These tools will help reduce potential errors in the different stages of the project.
