National action plan to prevent radon risks
The goal is to prevent radon-induced lung cancer
Radon is the most significant known cause of lung cancer after smoking. Of the approximately 2000 lung cancer deaths reported in Finland each year, radon exposure is estimated to be related to about 300. Radon exposure increases the risk of lung cancer, especially for smokers. Radon causes about 40 lung cancers each year in non-smokers and is thus the most significant known cause of lung cancer among non-smokers. Most lung cancers could be avoided by quitting smoking and reducing radon exposure.
This action plan sets long-term goals and means by which the risk of radon-induced lung cancer in Finland can be reduced. The main focus of the action plan is on reducing the radon concentration in indoor air, as radon in breathing air is usually the most significant source of radiation exposure for Finns. Radon gas can enter the indoor air from the soil and bedrock below and around the building, from construction products or from borehole water.
