  The success of the Randall-Sundrum scenario relies on stabilization of the
modulus field or the radion, which is the scalar field about the background
geometry. The stabilization mechanism proposed by Goldberger and Wise has the
consequence that this radion is lighter than the graviton Kaluza-Klein states
so that the first particle to be discovered is the radion. In this work, we
study in details the decay, production, and detection of the radion at
hadronic, $e^+ e^-$, and $\gamma\gamma$ colliders.
