The angular distribution of neutrino pairs emitted by a relativistic electron moving in a magnetic field is considered. It is shown that the particles are emitted predominantly in the opposite direction to the magnetic field. This asymmetry directly reflects the nonconservation of spatial parity in the given process. On account of radiation reactive forces, the electron is accelerated in the direction of the magnetic field. Expressions are obtained for the asymmetry parameter of the radiation and the radiation reactive force, depending both on the magnetic field strength and the electron energy and on its polarization.
