The particle size of a fission product aerosol and the distribution of fission products between particulate and vapour phases depend on the mechanism of release to the atmosphere. 

Filters Special filters have been developed to separate sodium oxide and fission product aerosols from air. The design criteria for these filters reflect the physical and chemical properties of sodium oxide and sodium hydroxide as well as the temperatures of these aerosols. Special Sanahed filters have been developed which attain a separation efficiency of 99,7 to 99,9%. They can be combined with wet scrubbers which can remove 70% of the sodium aerosols in a first step.
