ABSTRACT
The radiation emitted by nonrelativistic particles differs quantitatively and even qualitatively from the radiation from relativistic particles. Characteristic features of the radiation emitted by relativistic and nonrelativistic particles moving in vacuum. Radiation reaction and the limits of applicability of the classical theory. Radiative losses in the motion of a charged particle in a magnetic field. The radiation emitted by a nonrelativistic electron moving in a magnetic field is often referred to as "cyclotron radiation". The dipole radiation in this case generally does not predominate, and the most convenient way for estimating the radiation is to make use of the formulae for transition from one inertial frame of reference to another. Radiation emitted in a variety of real systems is similar to the radiation from a high-velocity dipole. The radiation generated in an undulator can also be used for detecting passing particles.
