In this paper we obtain an expression for the Dalitz plot of semileptonic decays of neutral baryons including radiative corrections up to order [alpha][ital q]/[pi][ital M][sub 1] ([ital q] is the four-momentum transfer and [ital M][sub 1] is the mass of the decaying baryon). The model dependence of the radiative corrections is kept in a general form which is suitable for a model-independent experimental analysis. The bremsstrahlung contribution is given in two ways. The first one leaves the triple integration over the photon variables to be performed numerically and the second one is completely analytic. Our result is suitable for high-statistics decays of ordinary baryons as well as for medium-statistics decays of charm baryons.
