STUDY ON IONIZATION EFFECTS PRODUCED BY NEUTRON INTERACTION PRODUCTS IN BNCT FIELD*

Abstract

The ionization effects of charged particles produced in neutron interactions for Boron NeutronCapture Therapy are considered here using SRIM Monte Carlo Code. The estimated values of these effects ina Plexiglas acrylic phantom are shown to agree well with the available experimental values in high Boronconcentration areas. As expected, the ionization effects from lithium and alpha particles are significant.However in the low Boron areas, proton ionization makes an important contribution and their effect onhealthy tissue should not be ignored.
