  We use previously developed radiative potential method to calculate quantum
electrodynamic (QED) corrections to energy levels and electric dipole
transition amplitudes for atoms which are used for the study of the parity
non-conservation (PNC) in atoms. The QED shift in energies and dipole
amplitudes leads to noticeable change in the PNC amplitudes. This study
compliments the previously considered QED corrections to the weak matrix
elements. We demonstrate that the QED corrections due to the change in energies
and dipole matrix elements are comparable in value to those due to change in
weak matrix elements.
