Abstract
The Čerenkov radiation from electrons in a plasma in a magnetic field has been calculated by Kolomenskiĭ, who determined the allowed frequency regions and the energy loss. It is shown here that his results are in error. The allowed frequency regions have a much more complicated dependence on the plasma frequency, gyrofrequency, and electron velocity than he indicates, and he overestimates the energy loss for electrons in the earth's inosphere by a factor of about 100. The total energy loss from slow electrons by Čerenkov radiation is comparable to their synchrotron loss, but is mainly at lower frequencies. For fast electrons, the Čerenkov loss is much smaller than the synchrotron loss.
