Outline of Final Research Achievements

"Boron Neutron Capture Therapy (BNCT)" utilizing the nuclear reaction between boron incorporated into tumor cells by drugs and thermal neutrons irradiated from nuclear reactors and accelerators as a method of treating cancer by radiation has received attention in recent years. However, a method for evaluating the complicated dose distribution has not yet been well established.
In this research, we applied a dosimeter which is equivalent to water (tissue) equivalent, called a three-dimensional gel dosimeter which can evaluate the dose in three dimensions. In order to establish its use method, basic characteristics were evaluated and important basic data for clinical use was obtained.
