Learn and experience at Tabloo

Tabloo allows students to not only see billions of years into the past but also look far into the future. Time, in fact, plays an important role in the phenomenon of radioactivity. The role of Tabloo is to keep the memory of the nearby radioactive waste repository alive for 300 years and beyond. But how will it do this?

Visit Expoo

Immerse yourself in an invisible world and experience radioactivity in a unique way. Discover how we manage radioactive waste and what challenges we face. Find out how the public can help to find solutions for radioactive waste. Learn all about what research is currently underway in the field of nuclear applications.

With dozens of interactive exhibits, Tabloo's permanent exhibition offers students a unique insight into the world of radioactivity. A visit to the expo with an audio guide takes between 1.5 and 2 hours. If you would like to explore everything down to the last detail, you should allow around 5 hours. You can also book a guide, and the tour is two hours' long.
