The influence of the non-dipole character of radiation on the spectral characteristics of the Kumakhov radiation has been analysed. It was shown that if γψL≦ 1, the non-dipole character can lead to an increase of the spectral intensity of radiation in its maximum. In heavy crystals the strong non-dipole character of radiation γψL> 1 leads to sharply expressed maximum in spectral distribution of the radiated energy. The influence of the non-dipole character on the temperature dependence of radiation is investigated.
