We calculate the O(\ensuremathαs) gluon bremsstrahlung corrections to the inclusive decay b\ensuremath→s\ensuremathγ, involving the full operator basis \stackrel^O1\ensuremath-\stackrel^O8. Confirming and extending earlier calculations of Ali and Greub, we give formulas for the total decay width as well as the perturbative photon spectrum, regarding the former as a necessary part of the forthcoming complete NLO analysis. We explore in detail the renormalization scale dependence of our results and find it considerably increased.
