Abstract
Alpha-spectrometric Pu determinations in aerosol samples collected aft er the Chernobyl accident in Austria show a Pu-238/(239(240))Pu ratio in the range of 0.33-0.76 with a most reliable value of 0.47. From Am- 241 measurements in old Pu preparations and air filter analyses also P u-241 activities have been calculated. The ratio Pu-241/(239(240))Pu d uring the main contamination period is 74.6+/-5.7, when maximum Pu-241 concentrations in air achieved 4.5-6.0 mBq/m(3).
