We study radion phenomenology in the context of avor shining in warped extra dimension models. In this unique setup, originally proposed by Rattazzi and Zaffaroni, solutions to the gauge hierarchy problem and the new physics avor problem are unified. A special role is played by the vacuum energy on the branes, that naturally allows for avon stabilization and parametrically raises the radion mass. We note that the radion mass squared is suppressed only by the log of the weak-Planck hierarchy, and it is in the favored range of the standard model Higgs. We emphasize that the radion to di-photon, and to WW* can be promising discovery channels at the LHC, with a rate above that of the standard model Higgs. We find that the radion is unlikely to account for the excess in W plus dijet events as recently reported by the CDF collaboration.
