    "abstract": "We study energy deposition by light nuclei in tissue-like media taking into\naccount nuclear fragmentation reactions, in particular, production of secondary\nneutrons. The calculations are carried out within a Monte Carlo model for\nHeavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit. Experimental data on\ndepth-dose distributions for 135A-400A MeV C-12 and O-18 beams are described\nvery well without any adjustment of the model parameters. This gives confidence\nin successful use of the GEANT4 toolkit for MC simulations of cancer therapy\nwith beams of light nuclei. The energy deposition due to secondary neutrons\nproduced by C-12 and Ne-20 beams in a (40-50 cm)^3 water phantom is estimated\nto 1-2% of the total dose, that is only slightly above the neutron contribution\n(~1%) induced by a 200 MeV proton beam.",
