The leakage spectra of 14MeV neutrons from spheres of iron and boron-in- polyethylene with three different mass ratios of boron carbide to polyethylene were measured over the energy range of 20 keV to 16 MeV by using proton recoil method. The integral leakages and removal cross sections at different lower cut-off energy were given.
