✦ Synopsis

The properties of channeling radiation spectra for above 100 GeV electrons have been studied with account of multiple scattering and radiation cooling. It has been shown, that the shape of a spectrum does not depend neither on energy of electrons, nor on the atomic number of a target when the energy of electrons exceeds $1 TeV. The consideration is based on the uniform field approximation (UFA). Simple phenomenological expressions are presented which describe the radiation spectrum with good degree of accuracy. It has been shown, that the radiation length in the high energy limit depends weakly on the energy of incident electrons.
