Abstract :
We have evaluated configurations of 1-meter long ZnS/6LiF scintillator screens, wavelength shifting readout, and moderator to find an optimum meeting minimum standards for neutron portal monitoring applications. MCNP5 modeling predicts that by embedding 3 polyethylene cylinders covered with ZnS/6LiF scintillator in a rectangular moderator, a sensitivity of 2.6 cps/ng 252Cf at 2 m can be achieved.
