Radon testing


All property owners must have tested a certain percentage of their housing stock and corrected any excessive concentrations of radon by 2020. This decision was based on one of the 15 environmental objectives adopted by the Riksdag – “A Good Built Environment. The National Board of Housing, Building and Planning (Boverket) is responsible for the objective, to which several interim goals are attached, one of which refers to radon.

Timetable 

The radon testing started in 2016 and will continue until 2019. The only area remaining is Gylleholm och the testing there is scheduled to autumn/winter period 2019. 

Completed radon testing

  • Spring 2016: Bokompakt and Klosterängen
  • Autumn 2016: Kämnärsrätten, Studentlyckan and Tomegapsgården
  • Spring 2017: Delphi
  • Autumn 2017, stage 1: Parentesen, Magasinet and Vildanden
  • Autumn 2017, stage 2: Ulrikedal, Dammhagen and Sparta

About radon

Radon is a radioactive, odourless and invisible gas that is found in air, soil and water. Soil is the most common source and it is divided into three categories: low, normal, or high risk. The municipalities usually study the soil, so you can contact your municipal environmental administration to find out which risk zone you live in. Radon in a home can also come from aerated autoclaved concrete (known in Sweden as “blåbetong”), a building material that was used from the 1930s until the end of the 1970s. 

Radon gas is formed when the element radium decays, and then when the gas decays, radon progeny are formed. These stick to dust particles, which is how they can enter the airways and lungs. Radon can cause lung cancer.

Why are we testing? 

We are testing the levels of radon in our housing due to a parliamentary decision, that applies to all property owners in Sweden. At the same time, we want to ensure that indoor air in our student housing is of good quality.

The testing 

Radondosor300We will be testing all housing areas. Although not every single housing, but a certain percentage selected randomly

The radon concentration in indoor air is measured in Becquerel per cubic metre, Bq/m3. The testing will be performed during the period of 1 October – 30 April (when window are usually kept closed) and must continue for at least 60 days. When testing we use radon detectors, small containers with a track film, which are placed in the housing. After the end of the period, the detectors will be collected and sent for analysis. We follow the method description issued by the Swedish Radiation Safety Authority.
