Outline of Final Research Achievements

In neutron capture therapy (NCT), an essential factor is how to control the dimensions of the irradiation field. From the viewpoint of quality assurance and quality control (QA/QC), it is important to measure the three dimensional distribution of the thermal and epithermal neutrons, which are useful in NCT, and fast neutrons and gamma rays, which are not desirable for NCT. This project proposes the utilization of the gel detector as a three-dimensional radiation detector, combined with the enhancers to detect the aimed beam component for this purpose. Consequently, the required condition of the methodology was revealed. The research is still ongoing to realize the method in clinical trials, by evaluating the accuracy and improving the procedure.
