A set of scattered neutron counts corresponding to different paraffin (simulated grease stain) thicknesses was obtained by using an experiment setup, which consists of a neutron source of ~(241)Am-Be,a Li-glass detector and a micro-computerized multi-channel spectrometer etc. In addition, by using Monte-Carlo program with the similar geometry, scattered neutron counts for different paraffin thicknes-ses were obtained for a ~(241)Am-Be energy spectrum, a ~(252)Cf spectrum and a 14MeV spectrum. In simula-tion, the detection efficiency of the Li-glass detector was considered. Comparison and discussion were carried out between the experimental and simulation results.
