Our History

Radonova Laboratories, formerly Landauer Nordic and Gammadata Mättekinik, was founded in 1986 following the Chernobyl nuclear accident. After the disaster, the Swedish government commissioned a group of researchers from Uppsala University to measure the fallout, and a young company with a bright future was born.

Radonova is now a global leader, conducting large-scale radon measurement in over 80 countries. We have built a strong reputation for our instrument quality, professional values, and innovative technologies.

Radonova Laboratories is part of the Lagercrantz group.
