摘要：
Alpha-spectrometric Pu determinations in aerosol samples collected after the Chernobyl accident in Austria show a238Pu/239 (240)Pu ratio in the range of 0.33–0.76 with a most reliable value of 0.47. From241Am measurements in old Pu preparations and air filter analyses also241Pu activities have been calculated. The ratio241Pu/239 (240)Pu during the main contamination period is 74.6±5.7, when maximum241Pu concentrations in air achieved 4.5–6.0 mBq/m3.
