We show that conventional quasistationary (coronal, or improved coronal) approximation for the energy loss due to the impurity radiation in practice can never be applied to the investigations of the impurity radiation driven instabilities in the edge plasmas due to relatively slow evolution of the impurity population over ionization states. We show that taking into account the effect of the evolution of the impurity population over ionization states results in a very significant change of the growth rates of the radiative driven instabilities and the structure of the shock wave in the radiative plasmas and leads to the strict conditions for the existence of the shock wave.
