Abstract—The parameters of the electron-positron plasma and intensity of X-ray emission from hot spots in the polar regions of radio pulsars are calculated using a Goldreich–Julian model in the regime of free electron emission from the neutron star surface. In this case, the electric field is generated by the general relativistic effect of inertial frame dragging. The results obtained are in agreement with the observational data for the radio pulsars PSR 1055-52 and PSR 1929+10, and for the Geminga pulsar (E0630+18).
