Statistical analysis of the long-term observations of the characteristics of radioactive aerosol in the Bypass system of 'Ukryttya'

Statistical analysis of dynamics of the radioactive aerosol parameters in the Bypass system for the period of 2003-2010 has been performed. The correlations between the parameters and variability of their seasonal trends have been estimated. For the long-term dynamics of the airborne concentrations og 137Cs, 241Am and sum of β-emitting radionuclides the well-expressed global trends have been found, which can be approximated with the exponential dependences. The impact of the weather conditions near the ChNPP on the radioactive aerosol concentration in the Bypass system has been quantified
