Research Abstract

Beam-profile monitor system using gas activation for boron neutron capture therapy was constructed, and its characteristics and validity were confirmed. It was confirmed that this system could measure and estimate the dose during a typical BNCT clinical study with the irradiation time of thirty to ninety minutes. It was confirmed that the uncertainty for the does estimation by this system was almost five percent, compared with the other dose measurement and estimation methods. It is planned that this system is used under the actual BNCT clinical studies, with confirming its safety and stability.
