Abstract
Following the accident at the Chernobyl nuclear power plant on 26 April 1986, about 2 x 10^18 Bq of condensable radioactive materials were released, the majority of which was deposited in Europe. Most of the released material was in particulate form, whereas noble gases and most of iodine were in gaseous form. Sometimes the activity of even a single "particle" may be so high that may cause a severe health hazard. Radioactive particles released from Chernobyl have been descibed by many as "hot particles" where "hot" is synonymous with "highly radioactive". The aim of this study is to characterise such particles with regard to their elemental, mineralogical and radionuclide composition.
