Abstract : Fluxes of electrons and protons in Jupiter's radiation belts are calculated with the source, radial diffusion inward from the solar wind, and the loss, synchrotron radiation. The calculations are tested against the measured radiowave wavelength distribution, the radiowave distribution with distance from Jupiter and the degree of polarization of the radiowaves. The Fokker-Planck equation is solved using the method of Farley and Walt with the flux fixed at the outer boundary and zero flux at Jupiter's surface. It was found in agreement with Brice and McDonough, Jacques and Davis, and Birmingham et al. that the usual magnetic and electric diffusions, that vary as L sup 10 and L sup 6, respectively, are insufficient to furnish the required electrons and that the diffusion driven by ionospheric winds of Brice and McDonough is strong enough to furnish Jupiter's belts.
