摘要：
Radionuclide composition in particles of the smoke plume from the forest fire in the 30-km zone around the Chernobyl NPP was studied. The activity ratios of the radioactive isotopes of cesium, cerium, and plutonium in the forest combustible materials and in the aerosols yielded by the fire showed that these aerosols are enriched in radioactive cesium occurring predominantly on submicron particles transported to long distance. The fire area gets depleted in cesium radioisotopes and, to a lesser extent, in other radioactive products generated by the Chernobyl accident.
