The momentum spectrum and the polarization of charginos and neutralinos in squark decays are affected by gluon radiation in the decay process (q) over tilde -> q (chi) over tilde (g). We determine these corrections and study their impact on the [ql] invariant mass distributions for leptonic (chi) over tilde decays. The higher-order corrections, though small in general, can be sizeable near pronounced edges of the final-state distributions.
