Finnish air monitoring data

Finnish air monitoring data




AbstractSTUK operates eight sampling stations for nationwide monitoring of airborne radioactive substances. Sampling is performed using a specially designed sampler which filtrates large amounts of air. Airborne radioactive particles are deposited on glassfibre filters whereas charcoal filters are used for gaseous species and, for instance, iodine. Small quantities of radioactive material are detected in the samples using sophisticated laboratory analysis. In the laboratory the glassfibre filters are analysed with a high-resolution gamma-ray spectrometer. Airborne artificial radioactive substances were estimated to cause a radiation dose of about 0.0000001 mSv per capita in Finland in 2009.

QualityData have been collected as a part of STUK’s environmental monitoring program since 1986. Since 1999, radioactivity determinations have been carried out using an accredited method with regular quality control through intercomparisons, calibrations and blank samples. Prior to 1999, in-house quality evaluation took place with similar quality assessments.
