Abstract

Abstract: In boron neutron capture therapy, it is important to evaluate the dose administered to a patient's body outside the tumour area. The exposure dose is evaluated by calculation; however, the calculated value must be validated using a measured value. The dose evaluations based on the measured neutron spectrum are investigated. Multi-foil activation, combined with a LiCaAlF6 scintillation detector and an imaging plate, is proposed as a measurement method. The proposed method can measure the neutron spectrum at various points quickly. Highlights: Multi-foil activation and LiCaAlF6 scintillation detection are combined. An imaging plate is employed to measure the metal-foil radioactivity. The results suggest that the neutron spectrum can be evaluated in short time. This method has potential application in dose evaluation during BNCT irradiation.
