Layered shielding design for an active neutron interrogation system [PDF]
Radiation Physics and Chemistry, 2016 Abstract The use of source and detector shields in active neutron interrogation can improve detector signal. In simulations, a shielded detector with a source rotated π/3 rad relative to the opening decreased neutron flux roughly three orders of magnitude. Several realistic source and detector shield configurations were simulated.
