An analysis of radiation induced instabilities in an expanding plasma with considerable presence of dust particles and equilibrium cooling is presented. It is shown that the equilibrium expansion and cooling destabilize the radiation condensation modes and the presence of dust particles enhances this effect. The results obtained are examined in the context of ionized, dusty-plasma environment such as that of a planetary nebula. It is shown that due to nonstatic equilibrium and finite equilibrium cooling, small-scale localized structures formed as a result of thermal instability, become transient, which agrees with the observational results. The dust-charge fluctuation is found to heavily suppress these instabilities.
