Calculation of dose components in boron neutron capture therapy BNCT using the Los Alamos MCNP code

Abstract

The main object of this study is the simulation, using the MCNP code, of the head of a patient to calculate the time in boron neutron capture therapy (BNCT) using neutron beams at the epithermal range [0.5ev-1keV] and at fast range (1MeV).

The simulation results showed that total dose, in the epithermal energy ranges: decrease with increasing of neutron energy and with increasing depth of tumor where it reached a maximum value at (2-3)cm depth. In case of fast neutrons at(1MeV), the maximum value of dose is located at point of Entrance of the neutron beam to the tissue.
