In connection with the active space exploration, the studies of the effects of heavy ions are currently of particular interest. Cosmic radiation is primarily composed of protons and other ions with energies of >10 MeV. We have modulated the effect of cosmic radiation by using heavy-ion beams at the Heavy-Ion Accelerator in Dubna (JINR). Particularly, we have investigated the biological effects induced by accelerated boron ions with the energy of 12-34 MeV/n and linear energy transfer (LET) 42,
