Outline of Final Research Achievements

In the radiation therapy, X rays, gamma rays, protons and so on have been used. In this study we use neutrons. This method is called Boron Neutron Capture Therapy (BNCT). Boron is absorbed in cancer and expose neutrons. Then the boron emits alpha rays of which range is about the size of cancer cells. So each cancer cell will be killed by this method. The traditional way of radiation therapy is as like to say "burn cancer mass". This method is especially useful for the brain tumor which invade in the healthy cells. Before we used reactor neutrons, however in this study we developed a target system and real time neutron measurement system for the proton accelerator, which will be easily installed in each hospital.
