Radon measurement service for business premises and residential properties

Radon is an odourless, tasteless and colourless radioactive gas that enters the indoor air from the soil. After smoking, radon is also the second most common cause of lung cancer in Finland. Radon concentrations of indoor air in Finland are among the highest in the world.

Requirements set forth in the Radiation Act: Radon measurement must be carried out everywhere in Finland in workspaces that are completely or partially below the ground level and in the first floor premises if the workplace is located in a municipality or postal code area where measurements are required. Workplaces located on gravel ridges should also be measured everywhere in Finland.

Radon problems are almost always fixable

  • The radon exposure inspection is carried out with measuring devices approved by the Radiation and Nuclear Safety Authority (STUK).
  • The measurements must be made between 1 September and 31 May. The measurement takes two months.
  • The most typical renovation sites are detached houses.

If any problems are observed, the situation is reviewed in the affected premises. This includes an expert’s proposal for fixing the situation.
