We evaluate the impact of radiative corrections in the ratios 
when the meson M is a K or a 
. Employing the cuts on 
and the reconstructed B-meson mass presently applied by the LHCb Collaboration, such corrections do not exceed a few 
. Moreover, their effect is well described (and corrected for) by existing Monte Carlo codes. Our analysis reinforces the interest of these observables as clean probe of physics beyond the Standard Model.
