Abstract
The dominant one-loop radiative corrections to atomic wave functions. those associated with vacuum polarization in the nuclear Coulomb field, are eval uated for the 6s-7s parity-nonconserving transition amplitude in Cs-133. Th ese corrections increase the size of this amplitude by 0.4% and, correspond ingly, increase the difference between the experimental value of the weak c harge Q(W)(Cs-133) and the value predicted by the standard model.
