radonpitoisuus

Radonpitoisuus is a term used in Finland to describe the concentration of radon in the indoor air. Radon is a naturally occurring radioactive gas that can seep into buildings from the soil and ground. It is a product of the radioactive decay of uranium in the earth's crust.

Exposure to high levels of radon is considered a health risk, as it can increase the risk of lung cancer. The European Commission has established a limit for radon concentration in indoor air of 300 Bq/m3, which is used as a guideline for action levels. In Finland, the average concentration of radon in indoor air is typically around 100 Bq/m3, but levels can vary greatly depending on the location and building type.

Factors that can influence radon levels in indoor air include the type of soil and rock beneath the building, the presence of radon-prone construction materials, and the height of the building. High levels of radon are often found in buildings constructed on top of a radon-rich soil or in areas with high concentrations of uranium in the bedrock.

In Finland, radonpitoisuus is typically measured in homes, offices, and other buildings using detectors that measure the concentration of radon over a period of time. The results are used to determine if remedial action is needed to reduce the radon levels. Measures to reduce radon levels in indoor air include improving ventilation, using radon-resistant construction materials, and installing radon removal systems.
