We study the e+e-→Zφi→Zjj process, where φi is the Higgs and/or radion boson. The implications of the radion effects on the preliminary ALEPH data are also discussed. The case of a lighter radion than the Higgs boson is disfavored by the ALEPH analyses of the b tagged four-jet data, since the radion predominantly decays into two gluon jets due to the QCD trace anomaly. If the radion is highly degenerate in mass with the Higgs boson, the cross section can be increased more than at the one sigma level, with a natural scale of the vacuum expectation value of the radion.
