In the light of recent experimental observation of the Radiation Amplitude Zero (RAZ) in W{gamma} production by CDF at Fermilab, we consider its consequences. Is the RAZ unique to the Standard Model (S.M.)? Although it is not for {bar {nu}}{sub e}e{sup -} {yields} W{sup -}{gamma}, in the case of d{bar u} {yields} W{sup -}{gamma}, which is the case of experimental interest, observation of the RAZ implies that the S.M. must be correct.
