We obtain an expression for the Dalitz plot of semileptonic decays of charged and neutral hyperons including radiative corrections to order {alpha} and in the approximation of neglecting terms of the order of {alpha} times the momentum transfer. The model dependence of the radiative corrections is kept in a general form within this approximation, which is suitable for model-independent experimental analysis. The bremsstrahlung contribution is given in three ways. The first one leaves the triple integration over the photon variables to be performed numerically; the second one leaves only a single numerical integration step to be performed; and the third one is completely analytic.
