High energy ion beams such as carbon beams has physical characteristics such as Bragg curve, high LET, and nuclear reactions producing fragmentations. Therefore, understanding these properties well is essential for further improvement of carbon radiotherapy and manned space activity. We had, therefore, the following six presentations relevant to these issues from the measurements of fragmentations, lineal energy distributions in microdosimeric approach and neutrons with the active beams of carbon-ions therapy, to the depth dose distribution of various ions inside a human head phantom.}, pages = {i30--i31}, title = {Review of Session 6: Medical Physics}, volume = {55}, year = {2014} }
