An axisymmetric model is used to study changes in the shape of the Earth’s radiation belts and energy spectra of charged particles in them during a geomagnetic field reversal. Regions of stable existence of radiation belts are obtained analytically by generalizing the Størmer theory to the case of an axisymmetric quadrupole. An reversal scenario is proposed in which it is shown that a gradual reduction of radiation belts can occur with a decrease in the dipole component of the modern geomagnetic field. The spatial and energy distributions of the flux density of protons and electrons are obtained, which made it possible to determine the maximum dose rate of radiation on various magnetic shells during the reversal process.
