Study on the dose evaluation using glass rod dosimeter for boron neutron capture therapy

Boron neutron capture therapy is one of the radiation therapy using high intensity neutron up to 109 (cm− 2 s− 1). To evaluate prescript dose, it is important to separately detect thermal neutron flux and gamma dose. In our institute, Thermo-Luminescence Dosimeter (TLD) with the low sensitivity for thermal neutron to detect gamma ray dose, gold foil to detect thermal neutron flux have been used. TLD for detecting gamma ray dose at mixed field of intense neutrons can not be available because of discontinued products. Furthermore, we have successfully established the accelerator based neutron source for BNCT, it is desirable to develop new dosimeter instead of TLD.
