Biological effects caused by ionizing radiation have been investigated mainly using photons due to restrictions on available radiation sources. While HIMAC is the first synchrotron in the world specifically constructed for medical use, NIRS accepted and promoted basic sciences proposed by domestic and international researchers. Research at HIMAC produced many fruitful outcomes in high-LET radiation biology. We here review these outcomes and introduce a new development in the biology field using heavy-ion beams.
