Several experiments have been performed in which UF/sub 6/ was released into air under static conditions in a 6 m/sup 3/ release chamber in order to characterize the solid products of hydrolysis as the amount of UF/sub 6/ released was increased. An aerosol concentration of approx. 25 gm/m/sup 3/ (150 gm) was the largest achieved. Electron microscopy was used to determine the morphology of the aerosol particles and to obtain geometric size measurements from micrographs and a cascaded impactor was used to obtain aerodynamic size measurements by measuring particle masses. Particle sizes and rate of particle size change were observed to be dependent on aerosol concentration.
