Keywords:BNCT, accelerator driven neutron field

In previous work at Kyushu university, on the assumption to use the FFAG (Fixed Field Alternator Gradient) accelerator in the university as a source of a proton beam, the neutron field for BNCT(Boron Neutron Capture Therapy) has been proposed by using the PHITS code. In this work, relative biological effectiveness (RBE) was estimated after calculating cell survival fraction for an animal cell by using PHITS code.
