A workshop on citizen science in radioactivity measurements: empowering Europeans for better environmental monitoring

A 1 day workshop on citizen science in radioactivity measurements was organised by the French nuclear safety and radiation protection authority (ASNR) in June 2025 in Brussels, gathering nuclear safety authority representatives, research institutes, citizen radiation measurement networks and civil society representatives including Nuclear Transparency Watch.

The aim was to provide an overview of currently existing citizen radioactivity measurements projects in Europe, their structures and their objectives. An exhibition of selected technical materials was arranged. Key objectives of the workshop included ensuring the sustainability of citizen initiatives and integrating citizen data into decision-making processes, with a particular focus on widening participation in Eastern Europe. Participants also discussed existing gaps and difficulties and explored potential future projects.
