    The main influence factors of thermal neutron radiography include collimation ratio,cadmium ratio,scattering neutron,spatial distribution of neutron flux and so on. In this paper,the influence factors on thermal neutron imaging quality are analyzed by Monte Carlo simulation,and relevant measures are proposed for quality improvement of the thermal neutron imaging technique.
