Makhon'ko] The character of the time variation of the average yearly concentration of137Cs in the near-ground atmosphere of the USSR and Russia in 1954-1999 as well as the special features of the yearly variation of the average monthly concentration in 1981-1985 after the last nuclear explosion in the atmosphere (1980) are examined. The role of wind uplift of radioactive dust from the ground in contamination of the air near the ground by137Cs after powerful nuclear explosions in the atmosphere were discontinued and after the Chernobyl accident in 1986 is discussed. It is shown that in the last few years the137Cs concentration in the air at the ground is almost completely due to wind uplift from the dry ground and advection on a global scale. The coefficients of wind uplift and deflation, the velocity of wind uplift, and the size of aerosol particles-137Cs carriers—are estimated. 3 figures, 14 references.
