Radionuclides from the Fukushima Accident in Europe - Modelling the Air Mass Transport
Measurements of airborne radioactive aerosol concentrations of I3II, 131Cs and 134Cs were carried out in daily samples after the Fukushima disaster during the period of March - April, 2011. Rather diluted activities were detected in Vilnius on 23 March, 2011. The two maxima of activity concentrations were found which most probably are related to the complicated air masses transport Activity concentrations of 13II and 137Cs ranged from 12 mBq/m3 and 1.4 mBq/m3 to 3700 mBq/m3 and 1040 mBq/m3, respectively. Small variations in the activity ratio of l34Cs/ Cs (around 0.9) in measured samples were found. Results were compared with the data obtained during the Chernobyl accident. Modeling of long range air masses transport indicated a rather complicated pathway of radioactive cloud transfer across the Pacific and the North America to the Europe.
