Radiation is the transfer of heat by means of electromagnetic waves. To radiate means to send out or spread from a central location. Whether it is light, sound, waves, rays, flower petals, wheel spokes or pain, if something radiates then it protrudes or spreads outward from an origin. Such beams do radiate electromagnetic waves in the visible range. But radiation from a charge traveling in a magnetic field is a different matter from the Larmor effect which is supposed take place even in the absence of a magnetic field. Therefore cyclotron and synchroton radiation do not constitute empirical verification of the Larmor effect.
