Secondary Neutron Doses for Several Beam Configurations for Proton Therapy

Purpose To compare possible neutron doses produced in scanning and scattering modes, with the latter assessed using a newly built passive-scattering proton beam line. Methods and Materials A 40 × 30.5 × 30-cm water phantom was irradiated with 230-MeV proton beams using a gantry angle of 270°, a 10-c...
