摘要：

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 (i) the development of low neutron-sensitive TLD (UD-170LS-T2), (ii) the correlation of capture gamma-ray dose profile in a phantom for various collimator sizes, and (i ii) the formula for simple estimation of maximum gamma-ray dose on IOBNCT. The sensitivity of TLD as Co-60 gamma-ray kequivalent, for thermal neutron was 5.1 +/- 0.8X10(-14)(Co-60-Gycm(2)). The average relative deviations between predicted and measured gamma-ray dose for the mixed epithermal-thermal neutron beam in the phantom were, +/-8.5%. The accuracy of the gamma.-ray dose determination in the clinical BNCT may be improved by this simple method.
