Abstract
A novel technique for separating the out-of-field proton and neutron dose is presented. The technique combines measurements from special pin diodes sensitive to the non ionizing energy losses of protons and neutrons in silicon and standard clinical absorbed dose measurements. Preliminary testing shows good agreement with results from a GEANT4 study.
