The cross section for ZZ{r_arrow}ZZ with arbitrarily polarized Z bosons is calculated within the electroweak standard model including the complete O({alpha}) corrections. We show the numerical importance of the radiative corrections and elaborate its characteristic features. The treatment of the Higgs-boson resonance is discussed in different schemes including the S-matrix-motivated pole scheme and the background-field method. The numerical accuracy of the equivalence theorem is investigated by comparing the cross sections for purely longitudinal Z bosons obtained from the equivalence theorem and from the complete calculation. In this context the full O({alpha}) corrections are also confronted with the enhanced corrections of O({alpha}M{sub H}{sup 2}/s{sub W}{sup 2}M{sub W}{sup 2}), which were frequently used in the literature. {copyright} {ital 1997} {ital The American Physical Society}
