CHRONOLOGICAL ANALYSIS OF CONTAMINATION OF THE RUSSIAN TERRITORY BY LONG-LIVED RADIONUCLIDES

Evgeny Artyomov, Dr. Ekaterina Imshennik, Dr. Alexander Nakhutin

ABSTRACT

​

Contamination with biologically significant long-lived 137Cs and 90Sr radionuclides is observed in the entire territory of the Russian Federation. The sources of radioactive contamination of the dry land territory were surface, underground and atmospheric tests of nuclear weapons, underground peaceful nuclear explosions, regular and accidental releases from nuclear industry objects and nuclear power plants, accidents with military equipment. The spatial picture of the contamination was formed under the influence of processes of global, long-range, intermediate and local atmospheric transfer of radionuclides from the sources of contamination. Further evolution of contamination occurred as a result of radioactive decay and, to a lesser extent, processes of soil and atmospheric migration of radionuclides. A chronological analysis of published data allowed us to distinguish the main stages of contamination from 1949 to the present time.
