The radionuclide X-ray fluorescence method has been shown to be an eff
ective technique for multielement analysis of air samples. In the pres
ent paper the simultaneous determination of Fe, Zn, Pb, and Br in air
samples originating from three cities (Prague, Bratislava, Trencin) is
described. Used analytical system consisted of a radionuclide source
Pu-238 and Si-Li semiconductor detector connected to the multichannel
analyzer.
