Abstract

The results of Ge(Li) gamma spectrometric examination of hot particles prepared from dust in air samples collected in Budapest after the Chernobyl accident are presented. Fifteen particles with gamma activities in the range 25-600 Bq were separated from dust collected by an air conditioner filter between 29 April and 8 May 1986. The concentration of hot particles in air was estimated to be 5x10-5 particles per m3. On the basis of isotopic composition two different types of particles were found with geometric diameters in the range 3-10 μm. An order of magnitude estimate of the risk of lung cancer due to inhaled hot particles was estimated to be less than 10-10 for individuals resident in Budapest.
