Dose measurement in BNCT is difficult because of the presence of epithermal neutrons and gamma-rays. From the standpoint of exposure dose management, it is desirable to measure both doses separately. In this study, a filtered glass dosimeter is used. And, two types of glass are used to extract contributions of neutrons and gamma-rays separately. Practically, fabricating different filters for each, and using one element that measures neutrons and gamma-rays simultaneously and another element that measures only gamma-rays (or neutrons), separate measurement can be achieved. In the meeting, experimental approaches are described together with theoretical background.
