  We investigate the possibility to disentangle the radions in the
Randall-Sundrum scenario from higgs boson at the next generation high energy
$e^+ e^-$ linear colliders. Due to trace anomaly, the radion coupling (and in
turn the branching ratio) to gluons is enhanced over the same for the Standard
Model (SM) higgs. We study the radion production at electron-positron
colliders, via the fusion of W-bosons in association with neutrinos, and
propose to investigate radion decay to a pair of gluons. At 500 GeV center of
mass energy, our signal is not very promising. We find our results are
encouraging for finding radion and differentiating it from higgs for center of
mass energies of 1 TeV and above.
