Measuring the stopping power of α particles in compact bone for BNCT
The stopping power of α particles in thin films of decalcified sheep femur, in the
range of 1.5 to 5.0 MeV incident energy, was measured by transmission of a backscattered
beam from a heavy target. Additionally, the film elemental composition was determined by
Rutherford Backscattering Spectrometry (RBS). These data will be used to measure boron
concentration in thin films of bone using a spectrometry technique developed by the University
of Pavia, since the concentration ratio between healthy tissue and tumor is of fundamental
importance in Boron Neutron Capture Therapy (BNCT). The present experimental data are
compared with numerical simulation results and with tabulated stopping power data of nondecalcified
human bon
