Activity measurement of gamma-ray emitters in aerosol filters exposed in Lithuania, in March-April 2011

Two aerosol sampling stations in Lithuania were simultaneously used for assessing consequences of the accident at the Fukushima Dai-ichi nuclear power plant. The maximum activity concentrations of Te-129m, I-131, Cs-134 and Cs-137 were 0.59 +/- 0.06, 3.5 +/- 0.3, 0.90 +/- 0.08, 0.90 +/- 0.07 mBq m(-3) at station #1 in Vilnius, and 0.29 +/- 0.03, 1.0 +/- 01, 0.41 +/- 0.04, 0.41 +/- 0.04 mBq m(-3) at station #2 in northeastern part of Lithuania, respectively.
