MIXED AEROSOLS OF CS-137 AND NH4CL

The behavior of Cs-137 during NH4Cl formation from the vapor is studie d. In the presence of a carrier (1 mg Csl), two types of radioaerosols are formed: (137)Csl and Cs sorbed on metal oxides found in the suppo rt for the radioaerosol generator. Both form mixed-micelle aerosols wi th NH4Cl, the strength of which is different and probably determined b y the surface properties of the radioaerosol. The ability of Cs-137 to form mixed aerosols with nonradioactive macrocomponents can be used t o mitigate the consequences of accidents.
