Controlled burning of experimental plots of forest or grassland in the Chernobyl exclusion zone has been carried out in order to estimate the parameters of radionuclide resuspension, transport and deposition during forest and grassland fires and to evaluate the working conditions of firemen. An increase of several orders of magnitude of the airborne radionuclide concentration was observed in the territory near the fire area. The resuspension factor for 137Cs and 90Sr was determined to range from 10-6 to 10-5 m-1, and for the plutonium radionuclides from 10-7 to 10-6 m-1 (related to the nuclides in the combustible biomass).
