Degenerate electron gas based on the model with gomogeneous positive background is considered. Electromagnetic interaction in such a system is treated with thermal QED formalism. Relativistic corrections are taken into account in weakly relativistic approximation. Fourier transforms of scalar and vector potentials created by a weak static source in the electron gas are obtained in RPA approximation. Vector potential is shown not to be screened. Scalar potential is screened at nonzero temperature. At zero temperature it decays with the distance by power law.
