[Radioactive aerosols formed by fires in regions polluted by products of the Chernobyl accident].
Fires during summer period of 1992 within 30-km zone near Chernobyl NPP lead to short-term increase of both 137Cs concentration in the air and ratios 137Cs/90Sr and 137Cs/238Pu as compared to quite conditions. The concentration of 137Cs resulted from the fires of various types was estimated. It was found that this value could exceed the maximum permissible concentration (MPC) for population if the soil contamination density was greater than 0.5 Ci/km2 and MPC for professionals at contamination density 7 Ci/km2. Fires lead to increase in inhaled radiation dose, whereas exposure dose rate remains unchanged.
