There are a number of different national and maximum values for radon levels in Swedish residences and in the workplace. These are drawn up by the National Board of Housing, Building and Planning (Boverket), the National Food Agency ( Livsmedelsverket), the Public Health Agency of Sweden (Folkhälsomyndigheten) and the Swedish Work Environment Authority (Arbetsmiljöverket).
There is a list below with current national and maximum values that the Swedish Radiation Safety Authority have compiled.
| National and maximum values for radon in indoor air | |
|---|---|
| 200 Bq/m³ |
The national value for radon levels in existing residences and amenities, which are used for general purposes. The Public Health Agency of Sweden’s general advice on radon indoors FoHMFS 2014:16 |
| 200 Bq/m³ |

| 0.36 x 106 Bq h/m³ per calendar year |
Maximum value for how much radon a person may be exposed to in one year. The value applies to workplaces, for work other than underground work. This corresponds to a radon level of approx. 200 Bq/m³ for an annual working time of 1,800 hours, i.e. normal full-time work. Maximum value for how much radon a person may be exposed to in one year. The value applies to workplaces, for work other than underground work. This corresponds to a radon level of approx. 200 Bq/m³ for an annual working time of 1,800 hours, i.e. normal full-time work.AFS 2011:18 |
| 2.1 x 106 Bq h/m³ per calendar year |
Maximum value for how much radon a person may be exposed to in one year. The value applies to underground work such as rock and mine works or construction work underground. This corresponds to a radon level of approx. 1,300 Bq/m³ for an annual working time of 1,600 hours, (standard working time for public works underground is 36 hours per week). Maximum value for how much radon a person may be exposed to in one year. The value applies to underground work such as rock and mine works or construction work underground. This corresponds to a radon level of approx. 1,300 Bq/m³ for an annual working time of 1,600 hours, (standard working time for public works underground is 36 hours per week).AFS 2011:18 |
| 0.72 x 106 Bq h/m³ per calendar year |
Maximum value for how much radon a person may be exposed to in one year. The value applies to underground work in completed and habitable rock shelters and installations in rock. This corresponds to a radon level of approx. 400 Bq/m³ for an annual working time of 1,800 hours. Maximum value for how much radon a person may be exposed to in one year. The value applies to underground work in completed and habitable rock shelters and installations in rock. This corresponds to a radon level of approx. 400 Bq/m³ for an annual working time of 1,800 hours.AFS 2011:18 |
There is also a national value for gamma radiation (a type of radiation that can damage the body’s cells) in new buildings. Blue aerated concrete, a construction material, emits gamma radiation, but in such low quantities that it is not normally a danger to health. But if the value is higher than 0.3 microsievert per hour (0.3 µSv/h), the radon level in indoor air should also be measured.
