Radonova, formerly Landauer Nordic AB and Gammadata Mätteknik AB, was founded in 1986 after the Chernobyl disaster in Ukraine, when nearly 10% of all radioactive caesium from the accident fell on densely populated areas in Sweden. The need arose to measure and check the safety of food and crops in Sweden. A group of researchers from Uppsala University was given a directive from the Swedish government to take charge of these necessary measurement tests. Soon Radonova expanded its business area to include radon measurement tests in indoor air. To date, our laboratory at Radonova has analysed more than one million measurements in residential buildings and on public premises in Sweden and Europe. Radonova is owned by the Lagercrantz Group.
