Abstract
Medical physics is very important in carbon ion radiotherapy, as it is in conventional radiotherapy using X-rays and in estimation of exposed dose in the space environment. High-energy ion beams such as carbon beams have physical characteristics such as the Bragg curve, high LET, and nuclear reactions producing fragmentations. Therefore, understanding these properties well is essential for further development of carbon radiotherapy and manned space activity. We invited, therefore, the following six presentations relevant to issues ranging from the measurement of fragmentations, lineal energy distributions using the microdosimetric approach, and neutron dose with active beam delivery of carbon-ion therapy, to the depth–dose distribution of various ions inside a human head phantom.

Further investigation is needed into the difference in clinical outcomes, including secondary cancer risk, between carbon-ion radiotherapy with active beams and that with passive beams.
