Interaction of CsI radioaerosols with artificially generated NH4Cl aer
osols in the steam-gas medium, yielding mixed aerosols of the composit
ion NH4Cl-CsI, is studied. Depending on the method of generation of NH
4Cl aerosols, mixed aerosols of two types are formed: agglutination an
d crystallization aerosols. In the latter case, CsI aerosols are cente
rs of crystallization of mixed NH4Cl-CsI aerosols.
