Indoor radon concentrations in the Vitebsk, Mogilev and Gomel regions of Belarus and assessment of the radon dose for the population

The summarized data on indoor radon concentrations and estimated effective radon doses in the Vitebsk, Mogilev and Gomel regions of Belarus are presented. The passive track detector method was used to carry out the indoor radon monitoring. The measurement results are summarized in the geoinformation database. The map of the annual radon equivalent equilibrium concentrations distribution in administrative districts was created. The analysis of the results revealed that in 2.3, 1.3 and 0.4 % of dwelling of the Vitebsk, Mogilev and Gomel region correspondingly, the indoor radon equivalent equilibrium concentration exceeded the regulatory established limit of 200 Bq/m³. For effective planning of further radon monitoring, maps of absolute and relative number of measurements per administrative district were built. The calculated effective radon doses for the population and comparison to those from the “Chernobyl” radionuclides showed that radon is the main contributor to the public exposure.
