MAN-MADE RADIONUCLIDES IN THE NEAR-THE-GROUND ATMOSPHERIC LAYER DUE TO THE FUKUSHIMA ACCIDENT
Abstract
The article presents information about the main observation results of radiometric departments of the Federal Service for Hydrometeorology and Environmental Monitoring for changes in the radiation situation on the territory of Russia following the accident at the Fukushima NPP. The obtained experimental data allowed to conclude that the volumetric activities of radionuclides in the near-the-ground atmospheric layer were by 3 to 6 orders of magnitude below the permissible volumetric activity set by Radiation Safety Standards (NRB-99/2009), and the correction to the density of soil contamination by cesium-137 was by 2 to 3 orders of magnitude less than the decrease of the density of contamination with this isotope of the global origin due to radioactive decay.
