Advantage of a dynamical (B/Gd) neutron beam cancer therapy over a stationary therapy

Abstract

This communication reports on a demonstration that a dynamical neutron beam is superior, in penetrating the surface of a (B/Gd)-loaded cancerous region, to a stationary neutron beam of the same intensity. The reported analysis of this complex problem is based on a one-group neutron diffusion theory with a periodic external neutron beam source in a one-dimensional geometry.
