It is well known that a radiation amplitude zero (RAZ) occurs in radiative W decay (W{sup {minus}} {yields} d{bar u}{gamma} or W{sup {minus}} {yields} e{bar {nu}}{gamma}). This RAZ can be used to measure the magnetic moment of the W boson to see if it has the gauge-theory value {kappa} = 1, and, in this way, test the Standard Model (SM). In this paper we prove that the RAZ in this process is unique and, thus, the experimental discovery of any zero in this process implies that there exists a RAZ and, hence, {kappa} = 1. 5 refs.
