Lithuania’s radon map has been updated

    In 2018 Radiation Protection Center performed indoor radon measurements in 40 residential buildings located in the municipalities of Mažeikiai and Telšiai districts. The Lithuania’s radon map was updated based on the obtained results.

   The average concentration of indoor radon within the municipalities of Mažeikiai and Telšiai districts was 113 Bq/m3. Measured indoor radon concentration values ranged from 23 to 218 Bq/m3 and did not exceed the reference level of 300 Bq/m3  

   It is to be noted that radon is a radioactive gas given off from soil and accumulating in the enclosed spaces and buildings. Radon decay products, in particular polonium (214Po, 218Po), lead (214Pb), and bismuth (214Bi) mostly contribute to the human exposure. Radon is removed from the respiratory tract after inhalation, but a large part of its decay products precipitate on the respiratory tract and via irradiation – induced damage of epithelium cells increase the risk of developing cancers of respiratory tract, especially lung cancer and other genetic changes.

   Data on indoor radon obtained in 2008–2018 has been provided to the European Commission Joint Research Center and can be seen on the European Radon Map https://remon.jrc.ec.europa.eu/About/Atlas-of-Natural-Radiation/Indoor-radon-AM / Indoor-radon-concentration.
