In order to estimate the maximum gamma-ray dose in the brain in Intra-Operative Boron Neutron Capture Therapy (IOBNCT), this study was conducted for (1) the development of low neutron-sensitive TLD (UD-170LS-T2), (2) the correlation of capture gamma-ray dose profile in a phantom for various collimator sizes, and (3) the formula for simple estimation of maximum gamma-ray dose on IOBNCT. The sensitivity of TLD, as Co -ray equivalent, for thermal neutron was 5.10.810(Co-Gycm)The average relative deviations between predicted and measured -ray dose for the mixed epithermal-thermal neutron beam in the phantom were 8.5%. The accuracy of the -ray dose determination in the clinical BNCT may be improved by this simple method.
