Fast neutron therapy

Fast neutron therapy utilizes high energy neutrons typically greater than 20 MeV to treat cancer. Most fast neutron therapy beams are produced from proton beams impinging upon beryllium targets. Radiation therapy of cancers is based upon the biological response of cells to ionizing radiation. Tumor cells typically lack effective repair mechanisms, so if radiation is delivered in small sessions, a process known as fractionation, normal tissue will... more
