Radon (englanninkielinen) -osioetusivun ingressi

Radon is a colourless and odourless noble gas that is present in the indoor air in homes and at workplaces. Radon-bearing air from the soil seeps into the house through openings and gaps in the base floor. Radon prevention in the construction phase is easier and less expensive than implementing mitigation measures afterwards.

According to Radiation Act 859/2018, Articles 146 and 155, the employer must notify STUK of the radon measurement results at the workplace.
