The ''model-independent'' part of the order-..cap alpha.. radiative correction due to virtual-photon exchanges and inner bremsstrahlung is studied for semileptonic decays of hyperons. Numerical results of high accuracy are given for the relative correction to the branching ratio, the electron energy spectrum, and the (E/sub e/,E/sub f/) Dalitz distribution in cases of four different decays: ..sigma../sup -/..-->..nenu-bar, ..sigma../sup -/..--> lambda..enu-bar, ..xi../sup -/..--> lambda..enu-bar, and ..lambda -->..penu-bar.
