Radon is an odorless and tasteless radioactive gas rising from the soil that is commonly found in indoor air and is estimated to cause about 300 cases of lung cancer each year. The presence of radon gas in low concentrations in the indoor air of buildings is common, but the risks associated with radon gas increase as the radon concentration increases.
The presence of radon gas can in no way be sensed, so radon measurement is the only way to ascertain the radon content of indoor air.
RADON AT WORKPLACES
According to the Radiation Act 859/2018, radon measurement of indoor air in workplaces is mandatory in several municipalities in Lapland. The measurement obligation also applies to workplaces located in certain postal code areas, as well as to workplaces located on sandy and gravel soils that are highly permeable to air and partially or completely underground. If you are unsure about the measurement needs of your workplace, our experts can map the measurement needs and, if necessary, plan and implement measurements on a case-by-case basis for both small and large objects.
RADON IN SMALL HOUSES
Radon levels vary significantly between regions. In addition to the soil in the construction area, the radon content of the indoor air is affected by, among other things, the structural types and connections of the building’s subfloor and plinth structures, as well as the building’s ventilation functionality. According to the Decree of the Ministry of Social Affairs and Health on ionizing radiation, the reference value for the radon concentration in the indoor air of an existing dwelling is 300 becquerels per cubic meter (Bq / m³) of air, and the reference value for the design and construction of a new building is 200 Bq / m³.
The official measurement of radon concentration is carried out with radon measuring jars between the beginning of September and the end of May. If necessary, our experts will be happy to help you determine the correct measuring range.
The official radon measurement approved by the Radiation and Nuclear Safety Authority will be carried out between the beginning of September and the end of May with radon measuring jars. The recommended duration of the measurement is three months, the minimum measurement time is two months.
