The analytical formula and the corresponding numerical results for the bremsstrahlung of semileptonic decays of charged baryons, in the region of the Dalitz plot that covers the four-body events which were not considered in previous calculations, are obtained. The formula is very accurate because it includes all the terms of the order {alpha} times the momentum transfer. The model dependence of the radiative correction is kept in a general form which is suitable for a model-independent experimental analysis. The bremsstrahlung contribution in terms of the energies of the produced fermions is obtained by analytical means. Our result is suitable for high statistics decays of ordinary baryons as well as for medium statistics decays of charm baryons. {copyright} {ital 1996 The American Physical Society.}
