Abstract

The ionization effects of charged particles produced in neutron interactions for Boron Neutron
Capture Therapy are considered here using SRIM Monte Carlo Code. The estimated values of these effects in
a Plexiglas acrylic phantom are shown to agree well with the available experimental values in high Boron
concentration 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 on
healthy tissue should not be ignored.
