  Using a time-dependent Galactic Cosmic Ray flux proportional to the halo Star
Formation Rate and including astration and neutrino-induced nucleosynthesis, we
have studied the evolution of lithium, beryllium and boron in the halo. Our
results set limits to the production of LiBeB by the neutrino-induced
nucleosynthesis in massive stars, in order to reproduce the observed constancy
of Be/Fe and B/Fe ratios, the lithium plateau and the isotopic ratios
evolution.
