The radiative decay of b → sγ in minimal supersymmetry (SUSY) was investigated using general squark flavor mixings which also included next-to-leading order (NLO) QCD corrections. The large NLO corrections were induced to Wilson coefficients by gluino-squark corrections to down-type quark masses. The destructive interference and suppression by renormalization group led to 'focusing effect' of reducing size of gluino corrections to branching ratio for μ > 0. At large tanβ for small flavor mixings, the constraints from radiative decay became weak with respect to minimal flavor violation.
