In English

Radon is a hazardous gas that may be present in high concentrations indoors. The higher the level, and the longer you are exposed to the gas, the greater the risk that you will be harmed by the radiation emitted by the gas. The Swedish authorities have set an indoor radon concentration target of below 200 Bq/m3 by 2020 for all homes in Sweden.

In Sweden, there are three sources which can contribute to indoor radon levels:

  • the soil
  • the building materials
  • the water

The main culprit among the building materials is autoclaved aerated concrete (AAC), which is referred to in Sweden as ”blue concrete” (blåbetong). AAC is a lightweight concrete that was invented and manufactured in Sweden between 1929 and 1975. The material contains various levels of uranium-rich alum shale.

When uranium decays, radon is formed, and when radon decays, different radon progenies are formed. They cause damage to our respiratory tract and lungs, which can eventually lead to lung cancer.

RadonAssistans performs measurements and investigations to determine the causes of elevated radon levels and suggests appropriate steps to mitigate high levels indoors. We can also assist with remediation​​.

Our customers are homeowners, house buyers, landlords and housing associations in southern Sweden (Skåne).
