Some results of experimental investigation into the dynamics of aerosol formation in the process of hydrolysis of uranium hexafluoride of low concentration under controlled conditions are presented. It has been found that at relatively high concentrations of UF6 (20 g/m3 and higher) the process of active hydrolysis with formation of uranyl fluoride aerosol particles completes for the first 20 to 25 minutes, and the particles formed have the size much smaller than the He-Ne laser wavelength and have no time to grow during the gravitational sedimentation. As the hexafluoride concentration decreases, the process of hydrolysis of residual (free) UF6 with formation of aerosol particles still goes on for a long time. The results obtained contradict the common opinion that hydrolysis of uranium hexafluoride of low concentration occurs only on surfaces.
