   Consideration of equilibrium radiation in the medium similar to plasma shows that spectral distribution of such radiation is distinct from Plank equilibrium radiation (black radiation). The physical reason of this difference consists in impossibility of distribution of photons with the dispersion law w = ck in systems of the charged particles. The thermodynamics of equilibrium electromagnetic radiation in plasma is considered also. It is shown that a difference of thermodynamic properties of such radiation from Plank radiation is characterized by the parameter a = ħW_V /T. It is essentially shown in such plasma mediums, where a ≥ 1. Application of the received results to plasma of metals (first of all in a liquid condition where the charged particles have no the distant order) and to plasma model of the early Universe is discussed.
