radonkoncentration
Radonkoncentration, or radon concentration, is the amount of radon gas present in a given volume of air or soil gas, expressed as activity per unit volume. The standard unit is becquerels per cubic meter (Bq/m^3); in some contexts, picocuries per liter (pCi/L) are also used, particularly in the United States. Radon is a radioactive noble gas produced by the decay of uranium and thorium in rocks and soils.
Radon enters buildings mainly through the ground, entering through cracks in foundations, joints, and service penetrations.
Exposure to elevated radon concentration over long periods increases lung cancer risk, especially for smokers. Radon
Measurement typically involves long-term detectors placed in living areas for three to twelve months to capture
Mitigation options include sub-slab depressurization, sealing of entry routes, and improving whole-house ventilation. In new construction,
