Simulation of elementary particles interaction with matter, considering target's heterogeneity and complicated geometry
Ruban Olga

The simulation of elementary particles interaction with matter is used for problems of radiation protection systems designing, nuclear physics, and dosimetry. Using heavy charged particles is of high interest in modern medicine: the hadron therapy is used for cancer treatment. Computer simulations in hadron therapy are necessary for calculating dose deposit, finding required beam parameters, treatment planning, and focusing systems designing.
In the present work, physical processes of hadron therapy were simulated using the Geant4 toolkit. The major task was to investigate the deposited dose profiles, the so-called Bragg peaks.
The developed applications based on Geant4 toolkit libraries allowed us to obtain the following results: simulate Bragg peaks for several biological tissues; investigate the effect of target’s heterogeneity and chemical composition variations on Bragg peak parameters; model Bragg peaks for targets of complicated geometry.
