Forest fires in the territory contaminated as a result of the Chernobyl accident; radioactive aerosol resuspension and exposure of fire-fighters

摘要

Studies were carried out to investigate the processes of resuspension and redistribution of radionuclides by fire in the territories contaminated as a result of the Chernobyl accident. In this set of experiments, the dispersed radioactive aerosol composition, the values of airborne radioactive aerosol concentrations, the resuspension factor, the resuspension rate, the depos- ition flux and the deposition velocity have been obtained for the different phases of a fire and at various distances from the fire.
