Results from radon measurements

Measured radon concentration in indoor air.The data report values for the radon measurements received by Umeå municipality. The data set is currently not complete, but work is ongoing on adding more radon measurements. There may also be more measurements made that the municipality is not aware of.In multi-dwelling buildings, measurements may have been made in several different apartments with different results but the location of the measurement is linked to the entrance address or property where the measurement has been carried out. The variations are mainly due to changes in outdoor temperature and wind power. The levels also vary over the day and from room to room. The ventilation system and how often it is aired also affect the radon content. Therefore, radon measurements must last for a long time, at least two months and be carried out during the cold season. Measurements made during a shorter period of time or outside the heating season are indicated only. It is important to note that if ventilation changes, windows are sealed, cracks occur fundamentally or if major renovations are made, a new measurement should be made. The Swedish Radiation Safety Authority also recommends that a new measurement be made if it has been more than 10 years since the last measurement was carried out. Partly for single incoming radon measurements and partly in connection with annual consolidated deliveries from radon laboratories.
