Radiative corrections to nuclear processes

This paper reviews early studies of radiative corrections (RC) to the muon and to the beta decays. One loop RC to beta decays of hadrons are significantly enhanced with respect to analogous corrections to the muon decay. The nature of this enhancement is explained. Ultraviolet sensitivity of the beta-decay RC, found in the early studies, is compared to and contrasted with the dependence of Standard Model corrections on the electroweak boson masses
