Are you about to buy an apartment and wondering if your new home is safe?

Kiinteistökauppa ja radon

Vigilant home buyers should always ensure their new home is checked for radon

Radon testing is becoming a common requirement for property sales in Finland. It is valuable for the seller to have proof of radon testing having been performed on the property for sale. Radon testing also ensures a safe and healthy home for the buyer with no additional costs in the future. Radon testing should always be performed or a radon agreement entered into before the sale of a property to ensure there are no unpleasant surprises or extra costs. For property sales, the seller must always inform the buyer of radon testing performed on the property. 

 

Threshold values for radon in apartments:

Apartments granted a planning permit on or after 1 April 2004:
According to Finnish building regulations, apartments must be built in such a way that the annual average concentration (200Bq/m³) of radon in indoor air is not exceeded.  Any concentrations higher than this are considered a construction defect, and the builder is responsible for fixing the issue. For indoor air quality to be considered good (2008), its radon concentration must not exceed 100Bq/m³.

Planning permit granted 1 November 1992–1 April 2004 (recommendation at the time):
When levels of radon observed during a 2 month integrating analysis performed between 1 November and 1 April exceed 240Bq/m3, the annual average value is considered to exceed the 200Bq/m3 annual average.

Planning permit granted on or prior to 31 October 1992:
When levels of radon observed during a 2 month integrating analysis performed between 1 November and 1 April exceed 480Bq/m3, the annual average value is considered to exceed the 400Bq/m3 annual average.
