Abstract: The high-frequency asymptotic behavior of the spectral density of the distribution of equilibrium radiation in a nondegenerate electron gas is considered. It is shown that, at high frequencies, the expression for equilibrium radiation in a collisionless electron gas undergoes a renormalization of zero-point oscillations.
