Assessment of The Relation Between Energy Of Primary Protons And Undesired Neutron Dose During Proton Therapy By Monte Carlo Method

Introduction: High-energy beams of protons offer significant advantages for the treatment of deepseated local tumors. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum -Bragg peak- near the end of range with a sharp fall-off at the distal edge. Alongside its advantages there are some point that they need to meticul...
