A relativistic quark model appropriate to a universal one-gluon exchange plus a screening confining potential motivated by lattice gauge theory is used in evaluating the exclusive rate for [ital B][r arrow][ital K][sup *](892)[gamma] arising from the quark subprocess [ital b][r arrow][ital s][gamma] with a view to test the sensitivity of this rate to the screening length. Relativistic as well as recoil corrections are included in numerical evaluations of the form factors. This procedure is extended to flavor-conserving radiative decays of ground-state mesons: [ital V](1[sup [minus]])[r arrow][ital P](0[sup [minus]])[gamma]. It is found that the screening length increases as one moves to the light sector, thereby providing information about quark-antiquark interaction at large distances.
