Despite the Wildfire in the ChEZ the Radionuclides Сontent in the Air of Kyiv And its Outskirts Remains Low — SSTC NRS

Specialists of the State Scientific and Technical Centre for Nuclear and Radiation Safety (SSTC NRS) conducted a series of forecast estimates of the spread of potentially contaminated clouds from the forest fire area in the Chornobyl Exclusion Zone (ChEZ).

The RODOS decision support system and the initial data published on the official websites of SAEZM and SES as of 10:00 on April 8, 2020 were used for modeling. According to the global data of the meteorological forecast GFS NOAA (USA), during the day of April 8, the wind direction in the Kyiv Oblast is variable.

Forecast calculations of the potential concentration of Cs-137 in the surface layer of the atmospheric air of the north-western part of Kyiv on April 8, 2020 showed that the maximum values ​​can reach 1.0-2.0 mBq / m3 between 13:00 and 15:00. This is much lower than the permissible concentration of Cs-137 (PC ^inhal В), by the Radiation Safety Standards of Ukraine (NRBU-97), which is set at 800 mBq / m3 rate.
