## Abstract

In this work, we establish certain equivalences between the localisation properties with respect to spherical Fourier means of the support of a given Borel measure and the *L*^{2}-rate of decay of the Fourier extension operator associated to it. This, in turn, is intimately connected with the property that the *X*-ray transform of the measure be uniformly bounded. Geometric properties of sets supporting such a measure are studied.
