Hours: Saturday, September 19, 2026, 11:00–18:00 | Sunday, September 20, 2026, 11:00–18:00
Discovering the Archives Preserved by the Curie Museum
The Curie Museum’s Historical Resource Center, usually open to researchers and readers, is opening its doors on this exceptional occasion.
Home to thousands of manuscripts, photographs, posters, scientific drawings, books and journals tracing the history of the Curie and Joliot-Curie families, the Radium Institute and the Curie Foundation, it stands as a major documentary heritage for the history of science.
This visit will offer insight into the challenges of preserving these collections.
Participants will be invited to discover the methods used to safeguard this written and visual heritage against the ravages of time, as well as the specific conservation constraints linked to documents from radioactivity research.
Participation terms : By reservation only. Limited spaces for ages 15 and up. Bookings open on September 1. - Free | Reservations required - https://musee.curie.fr/reservation

Cross-cutting perspectives on radioactive heritage: a legacy that is both endangered and at risk
From laboratory notebooks to measuring instruments, some traces of the history of radioactivity remain... radioactive. At the crossroads of the history of science, conservation, and risk management, radioactive heritage has become, today, a topic of growing reflection.
This encounter offers a dialogue between Thomas Beaufils, a specialist in these singular collections, and Nicolas Benoit, an expert in radioactive-waste management. By pulling back the curtain on this little-known scientific legacy, they examine the challenges it raises: should we preserve items that carry historical value when they also pose a risk? What preservation and safety methods are applied to their uniquely hazardous nature?
Conditions of participation: Subject to availability. Open to those aged 18 and over, students - Free | No reservation required
Schedule: Sunday, September 20, 2026 — 3:00 PM to 4:00 PM
