Abstract: Ratios of⁹⁰Sr/¹³⁷Cs and^239(240)Pu/¹³⁷Cs have been determined in surface air by radiochemical analyses of air filter samples collected at different cities in Austria during the period April, 28–May, 9 1986. The mean values of these ratios remain below 2·10⁻² and 1·10⁻⁵, respectively, i.e., several orders of magnitude smaller than those from fallout contamination after the atomic weapon tests in 1963. Already few such ratios enable a quick first assessment of radiological emergency situations.
