Abstract	Data on the radionuclide composition, volume activity, and dispersity of aerosols taken in 2010–2014 using Petryanov’s filters in rooms 012/7, 012/15, and 210/7 of the Shelter object, into which the lava-like fuel-containing materials (LFCMs) flew after the accident, are presented. In room 012/7, the volume activities of aerosols carrying the Chernobyl accident products are higher by an order of magnitude than those in rooms 012/15 and 210/7. In all the rooms, the carriers of the radioactive products of the accident are, as a rule, aerosols with the activity median aerodynamic diameter larger than 1 µm. This value suggests the dispersion origin of the aerosols. In room 012/7, the aerosols are larger than in the other two rooms. The identity of the radionuclide composition of aerosols and LFCMs in room 012/7 shows that aerosols arise from the degradation of the lava. Considerable difference in the radionuclide compositions of aerosols and LFCMs in rooms 012/15 and 210/7 shows that the lava degradation in these rooms is less intense and that the aerosol generation from the lava surface does not influence the radionuclide composition of aerosols.
