A key point of fast neutron radiography (FNR) is to decrease the effect of scattered neutrons on the imaging. This gives a preferable design of a shielding collimator system for FNR with a D-T neutron source. M-C simulation results showed that the neutrons scattered from the walls could be decreased to about one tenth
and the effect of contrast distortion induced by scattered neutrons was greatly reduced. And intensity of the fast neutron source increased by 20%.
