The full average radiation intensity of electrons and positrons channeled between crystal planes is calculated. Comparison of the results of these calculations with calculations using the parabolic approximation for the potential well of a channel is presented. The difference can in extreme cases reach two orders of magnitude. Estimates for the positions of the maxima of the frequency spectra are given. The number of quanta averaged over the angular distribution of the particles in a beam are found.
